Comment l'ESA va gérer le défi lié au torrent de données créé par le(s) satellite(s) Sentinel 2

Europe's eyes in space: How ESA's Sentinel-2 satellite scans pose petabyte challenge
http://www.zdnet.com/article/europes-eyes-in-space-how-esas-sentinel-2-satellite-scans-pose-petabyte-challenge/
Début de l'article
"By next year the Sentinel-2 mission will be capable of obtaining complete coverage of the Earth's land surface every five days. That potentially represents a huge amount of data for the European Space Agency to handle.
When the European Space Agency's Sentinel-2B satellite joins its 2A twin in orbit next year, the project's volume of data in the form of images of the Earth's surface will soar to up to two petabytes annually.
To cope with that data growth, ESA has just expanded the 2013 contract it awarded Spanish company Indra to take it up to 2020 and to include data management for the twin satellites.
Robust long-term global records of essential climate variables, such as greenhouse gas concentrations, sea-ice extent and thickness, and sea-surface temperature and salinity, are crucial to understanding and mitigating the consequences of climate change.
Europe's eyes in space focused on Earth are provided by the Copernicus program, headed by the European Commission in partnership with ESA, which coordinates the delivery of data from upwards of 30 satellites. Among them are the Sentinels, which provide a unique set of observations that need to be processed and archived.
ESA's initial 2013 contract with Indra used the company's facilities at San Fernando de Henares, 15km from Madrid, as one of the main data-processing and archiving centers, or PACs, for the Sentinel-2A satellite mission's ground segment."

Copernicus : le satellite Sentinel 3A se prépare au lancement
http://www.futura-sciences.com/magazines/espace/infos/actu/d/copernicus-copernicus-satellite-sentinel-3a-prepare-lancement-60178/
Extraits :
"En décembre, Sentinel 3A sera le troisième satellite du programme européen Copernicus à être mis en orbite.
Il a pour objectif l’observation en permanence des océans et des surfaces terrestres par optique multispectrale, infrarouge et altimétrie.
Sa construction a dû tenir compte d’un certain nombre de contraintes techniques et opérationnelles en raison des objectifs scientifiques de la mission."
"Après les lancements de Sentinel 1A (avril 2014) et Sentinel 2A (juin 2015), se prépare celui de Sentinel 3A. Le satellite sera lancé le 10 décembre par un lanceur russe, Rockot, depuis le cosmodrome de Plessetsk.
Initialement, il devait être lancé par Vega, mais les premiers lancements de ce lanceur étaient déjà réservés par d'autres missions. Sentinel 3B sera quant à lui bien lancé par Vega.
Sentinel 3 fait partie d'une mission d’observation de la surface des océans et des terres émergées au moyen d'instruments optiques à moyenne résolution fonctionnant dans le visible (couleur), le proche infrarouge et l'infrarouge lointain (température), mais aussi d’instruments radars fonctionnant par tout temps et permettant notamment de déterminer les hauteurs des océans et des grands lacs.

Copernicus Atmosphere Monitoring Service (CAMS) Announces a Major Improvement on Atmosphere Data Accessibility
http://www.prnewswire.com/news-releases/copernicus-atmosphere-monitoring-service-cams-announces-a-major-improvement-on-atmosphere-data-accessibility-582887411.html
"At the first CAMS summit in Athens on 14-16 June, ECMWF, in charge of CAMS on behalf of the European Commission, will launch a radically new interactive and ready to use version of its online platform of atmosphere data. Policy makers, scientific and business communities or citizens will benefit from an enhanced free-to-access array of customisable and "live" maps and charts in just a few clicks.
Some of today's most important environmental concerns relate to the composition of the atmosphere. The increasing concentration of the greenhouse gases and the cooling effect of aerosol are prominent drivers of a changing climate, but the extent of their impact is often still uncertain.
Air quality is also one of the major concerns throughout the world, affecting human health and life expectancy, the health of ecosystems and the fabric of the built environment.
The European Union's Copernicus Earth Observation programme uses and contributes to a worldwide network of thousands of sensors on land, in our oceans, and in the air, as well as a network of over 50 satellites providing millions of environmental readings every day.
To address these environmental concerns there is a need for data and processed information that is easily accessible.
That means, not only free of charge, but ready to use and designed to match users' needs.
Instant online design "à la carte"
To see the video presentation of the new CAMS online platform: https://youtu.be/r-nhoTxkR8U
The new CAMS interface provides dynamic visualisations without the need to download data into specialist tools or software, giving users access to maps, charts, animations and local time series based on information about atmospheric chemistry as generated by the Copernicus programme.
The Catalogue component provides the basis for users to easily find the many products, be it data, maps or documents. It includes an intuitive search system, improved filtering and clear display of the resulting information.
The new catalogue marks an important step in broadening access to the wealth of CAMS data as part of Copernicus's mission, supporting society to understand and adapt to our changing environment through world-leading science and technology

Face aux inondations, les capacités "anti crises" de Copernicus ont été activées en juin
Copernicus ou quand l’imagerie satellite permet d’aider à la gestion des catastrophes naturelles
http://fr.euronews.com/2016/06/03/copernicus-ou-quand-l-imagerie-satellite-permet-d-aider-a-la-gestion-des/
Pour aider la France et l’Allemagne à faire face aux inondations, le Service de gestion des situations d’urgence Copernicus a été activé. Géré conjointement par l’Agence Spatiale européenne et la Commission européenne, il utilise l’imagerie par satellite pour aider les secours à agir vite là où il le faut.
“Par rapport aux images aériennes ou celles prises par les drones, les images satellites présentent l’avantage de couvrir des zones beaucoup plus importantes, explique Stéphanie Battiston.
En France, nous pouvons couvrir le bassin de la rivière Le Loing dans son ensemble. Et lorsqu’il faut surveiller la situation sur plusieurs jours, nous pouvons voir l’ensemble du bassin d’un seul coup chaque jour.”
Stéphanie Battiston est l’une des responsables du Sertit, la structure qui traite les données du système Copernicus pour les rendre lisibles par les services d’intervention.
“Nous fournissons des cartes chaque jour en fonction des demandes des utilisateurs, ajoute-t-elle. Cela leur permet non seulement de dimensionner les équipes de secours nécessaires sur le terrain mais aussi de savoir où les envoyer précisément en priorité.”
Ce système est utilisé pour les catastrophes naturelles mais aussi celles d’origine humaine comme les marées noires, ainsi que dans la gestion des crises humanitaires.

Sentinel satellite returns 'game-changing' multispectral imagery | ||
30 Jun 2015 | ||
Sofradir and e2v sensors helping to take remote land monitoring to unprecedented levels, says the European Space Agency. | ||
The European Space Agency (ESA) payload, one of several that will eventually make up the “Copernicus” constellation, covers 13 discrete bands across the visible and near-infrared spectral regions and combines that with a 290 km swath width and a ground resolution of 10 meters per pixel. Sentinel-2A’s first image acquisition captured a view extending from Sweden to Algeria, through a large chunk of central Europe. It included a close-up the Po Valley in Italy, processed through the satellite’s high-resolution infrared channel. The French company Sofradir provided 12 infrared sensors for Sentinel-2A. |

(ce qui est très important, à la fois pour mieux comprendre le fonctionnement de la planète, le dérèglement climatique et pour mieux appréhender les catastrophes naturelles et en atténuer les conséquences pour l'humanité),
en particulier près des côtes, comme en Norvège.

"Hilary Wilson, Eumetsat's Sentinel-3 project manager, added, "After this intense five-month period we are looking forward to taking over the routine operations of the satellite from ESA and moving into what will hopefully be more than a decade of smooth operations bringing these important data to users worldwide.
"Working together with ESA, we are proud to have achieved this important milestone."
Baltic swirls. Credit: Contains modified Copernicus Sentinel data (2016)/HZG
The data have already been put through a reality check.
As part of the commissioning phase, ESA and Eumetsat engaged with users, who have provided feedback on these sample data products.
Susanne Mecklenburg, ESA's Sentinel-3 mission manager, said,
"It is very exciting to see the first data already being looked at by the operational and scientific community – the people who asked for the continuity of such measurements and defined their requirements in the first place.
"After only five months of commissioning, we have already released samples for most types of data products. The coming months will see a gradual ramp-up of our processing and data dissemination activities to make sure that the user community is served in the best possible way.
"The intention is to release first operationally qualified data products to all users in September."
The full mission comprises two satellites flying in a constellation to meet the demanding coverage and revisit needs of the Copernicus Services.
So while Sentinel-3A is well on the road to start delivering data that is expected to make unique contribution to the paradigm shift in monitoring our planet,
ESA remains busy preparing its identical twin for launch in 2017."

Sentinel-1 provides new insight into Italy's earthquake
http://www.spacedaily.com/reports/Sentinel_1_provides_new_insight_into_Italys_earthquake_999.html
Scientists from Italy's National Institute for Geophysics and Volcanism combined Sentinel-1 radar acquisitions over central Italy from before and after the 24 August earthquake to calculate the location, geometry and amount of slip on the source fault. The slip is distributed mainly in two patches of about 1 m. The aftershock seismicity (black dots) is clearly surrounding these patches, releasing the remaining stress along the fault. The red star is the main shock. Green stars indicate the highest aftershocks of the sequence (M > 4.3). Image courtesy Copernicus Sentinel data (2016)/ESA/INGV.

ESA held a tour of the new Sentinel 2B spacecraft on Tuesday, Nov. 15. The spacecraft is being prepared for a March 2017 launch atop a Vega booster from Kourou, French Guiana. Photo Credit: Jacques van Oene / SpaceFlight Insider
"The European Space Agency (ESA) provided a glimpse of the Sentinel-2B satellite that is set to launch atop a Vega rocket from Kourou, French Guiana, during a media event held on Tuesday, Nov. 15. The spacecraft’s review helped set the stage for its flight, which is currently set for this spring

With this launch, the first set of Sentinel missions for the European Union’s Copernicus environmental monitoring network are in orbit, carrying a range of technologies to monitor Earth’s land, oceans and atmosphere.
It also offers lots of opportunities for commercial companies to develop new innovative services. And, the free and open data policy allows every citizen to have updates for their own use.
When such a satellite constellation was designed 20 years ago not everyone was convinced Europe could do that. Aschbacher stated he is glad to see this has become reality and that it is now a large European success story.
Over oceans, it measures the temperature, colour and height of the sea surface as well as the thickness of sea ice. These measurements are used, for example, to monitor changes in Earth’s climate and for more hands-on applications such as marine pollution.
Over land, this innovative mission monitors wildfires, maps the way land is used, checks vegetation health and measures the height of rivers and lakes.
Data from the Copernicus Programme are used worldwide and are free of charge.

World’s largest Earth observation programme
This is the seventh launch of a Sentinel satellite in the last four years. It is a clear demonstration of what European cooperation can achieve and it is another piece to operating the largest Earth observation programme in the world, together with partners from the European Commission and Eumetsat, said ESA director general Jan Wörner.With this launch, the first set of Sentinel missions for the European Union’s Copernicus environmental monitoring network are in orbit, carrying a range of technologies to monitor Earth’s land, oceans and atmosphere.
First Sentinel constellation
ESA’s Director of Earth Observation Programmes, Josef Aschbacher, said with Sentinel-3B, Europe has put the first constellation of Sentinel missions into orbit – this is no small job and has required strong support by all involved. It allows to get a very detailed picture of our planet on a daily basis and provides crucial information for policy makers.It also offers lots of opportunities for commercial companies to develop new innovative services. And, the free and open data policy allows every citizen to have updates for their own use.
When such a satellite constellation was designed 20 years ago not everyone was convinced Europe could do that. Aschbacher stated he is glad to see this has become reality and that it is now a large European success story.
Over land and over sea
Copernicus relies on the Sentinels and contributing missions to provide data for monitoring the environment and for supporting civil security activities. Sentinel-3 carries a series of cutting-edge sensors to do just that.Over oceans, it measures the temperature, colour and height of the sea surface as well as the thickness of sea ice. These measurements are used, for example, to monitor changes in Earth’s climate and for more hands-on applications such as marine pollution.
Over land, this innovative mission monitors wildfires, maps the way land is used, checks vegetation health and measures the height of rivers and lakes.

CAP = politique agricole commune.
The EU will launch a new satellite this week as part of the ‘Copernicus’ initiative. The earth observation programme has proved to be useful in dealing with natural disasters and its importance will grow to manage EU funds including the Common Agricultural Policy after 2020, director Philippe Brunet said.
Philippe Brunet is director at the European Commission’s Directorate-General for Enterprise and Industry and is responsible for the Copernicus programme.
...
In what recent crises was Copernicus used?
The Copernicus Emergency Management Service (EMS) system is available to respond 24-hours per day, 365 days a year. In March, the EMS was activated for several floods in Greece, Croatia and Albania.
In April, the Spanish Civil Protection Directorate General activated the EMS to produce delineation maps showing the extent of the flood over six areas. Copernicus EMS was also used for earthquakes in Italy, floods in Germany and Ireland and to monitor hurricane activity in the US in 2017.
Thanks to this system, emergency managers, crisis responders and humanitarian actors all over the world have one more tool in their toolkit that can make their work more efficient and effective.
The new satellite launching this week will monitor ocean waste. The control of waste plastic is becoming a priority in the public agenda. How could this new satellite help reduce this waste?
Detecting plastic waste in the ocean is difficult because it is either spread in little micro plastic particles or sinks under the water.
Copernicus satellites can help in two ways. First, with ocean colour, we are able to observe the optical properties of waters, their transparency, turbidity, content in sediments and pollutants, such as phosphates, nitrates, iron, etc. Second, ocean waste affects the transparency and turbidity of water. Such observations give us a first indication of possible pollution that has to be checked with in situ observations if available.
Sentinel 3B has three types of different sensors that enable the monitoring of the sea level, sea surface temperature and what we call the ocean colour, which helps to characterise the bio geochemical content of the ocean.
Copernicus could also be used to better manage the CAP. Could it increase the efficiency of EU funds?
Earth observation data is very helpful for the management and control of the CAP. For many years, the data has been used by EU Member States to control farmers’ area aid declarations.
The high-resolution images guide a new approach of the CAP “control”. CAP monitoring is expected to be significantly enhanced in the coming years and the Commission departments responsible for space and for agriculture are working closely together to strengthen their cooperation.
The current discussion on CAP after 2020 includes new elements on environmental and climate targets, which are likely to lead to further demand for national and EU-wide performance indicators and reference baselines.
Amongst others, crop rotation requirements, carbon sequestration measures, may be considered, each setting particular conditions to the type and manner in which performance indicators should be measured with the use of Copernicus high-resolution data.
The UK plays an important role both in Copernicus and Galileo. The European Space Agency is in favour of maintaining British involved in both programmes. Are you in favour too?
The Union’s space programmes are of vast economic, societal and security-related value to Europe. The UK will become a third-party country on 30 March 2019. The consequences for all EU policies are being assessed and discussed among the Commission and the 27 Member States in the context of their “Brexit preparedness” work.
Indeed, now is the right time to start thinking about adjusting cooperation regarding the space programmes to the way the EU cooperates with other third countries in such matters.
The EU recently signed an agreement with India to exchange images. To what extent would this agreement make launching new satellites redundant?
In March, we signed Copernicus cooperation arrangements with India and three more partners in Latin America: Chile, Brazil and Colombia. Similar agreements have already been signed with the US and Australia. We are also planning to sign with the African Union as well as key neighbourhood partners.
Under these arrangements, the Commission will provide these countries with free, full and open access to Copernicus data. In return, the Commission will receive data from international partners’ satellites as well as regional observatory networks.
These agreements are not only political signatures but also real cooperation commitments for the upcoming years which can benefit the EU and its partners. India as well as other new partners will facilitate the EU’s access to data from its regional observatory networks of geophysical and meteorological data.
They will support the enhancement of the Copernicus data architecture and development of global products.

Weather alert systems, real-time communication and debit cards for refugees: the use of new technologies make humanitarian aid more effective, Commissioner Christos Stylianides said in an interview. EURACTIV’s partner Euroefe reports.The new satellite launching this week will monitor ocean waste. The control of waste plastic is becoming a priority in the public agenda.

EU mulls incentives for space technologies in farm controls
The European Commission is considering new proposals to encourage the use of technologies to monitor farm parcels receiving subsidies from the Common Agricultural Policy (CAP), an EU official told EURACTIV.com.Copernicus could also be used to better manage the CAP.

More space for more Europe
2018 will be a crucial year to shape a stimulating new narrative for EU space policy. Jean-Loic Galle lists a couple of key points ahead of the 10th EU space policy conference taking place in Brussels on 23 and 24 January.The EU recently signed an agreement with India to exchange images.
