  1. NELDA PROJECT / SESSION 3: Planning NELDA PROJECT / SESSION 3: Planning for NELDA II – –New test sites, Land New test sites, Land for NELDA II Cover Attributes, , and Processes and Processes to monitor to monitor Cover Attributes ON POTENTIAL THEMES & ON POTENTIAL THEMES & MECHNISMS FOR FUTURE MECHNISMS FOR FUTURE COOPERATION BETWEEN COOPERATION BETWEEN NELDA, POSTEL AND SIRS NELDA, POSTEL AND SIRS PROJECTS PROJECTS A personal position paper by G é rard BEGNI – MEDIAS-FRANCE ENVIROMIS-2006 - NELDA WORKSHOP 1

  2. NELDA / POSTEL / SIRS NELDA / POSTEL / SIRS Let us start from an African proverb: « WHEN TWO ELEPHANTS ARE FIGHTING, « WHEN TWO ELEPHANTS ARE FIGHTING, IT IS THE GRASS THAT SUFFERS » IT IS THE GRASS THAT SUFFERS ENVIROMIS-2006 - NELDA WORKSHOP 2

  3. NELDA / POSTEL / SIRS TRANSLATION FOR US RIGHT HERE : ♦ When researchers spend their time making non scientific ‘upstream’ job to get the information they need of, it is science that suffers ( except if upstream job is questionable). ♦ When several research teams spend their time making the same job, it is science that suffers (except if they agree from the begining to test different therories or compare different methodologies). ENVIROMIS-2006 - NELDA WORKSHOP 3

  4. NELDA / POSTEL / SIRS LOOKING FOR ELEPHANTS LOOKING FOR ELEPHANTS !!! FORGET ANY NAME, ACRONYM, etc. ENVIROMIS 2006 & PREVIOUS WORKHOPS EVIDENCED THAT WE NEED NOW NOW AN OVERARCHING, TOP LEVEL ENDORSED TOP LEVEL ENDORSED INTERNATIONAL ORGANIZATION TO LEAD INTERNATIONAL AN INTEGRATED INTEGRATED SET OF STUDIES ABOUT NORTHERN EURASIA AND ESPECIALLY SIBERIA UNDER SEVERE ENVIRONMENT, ANTHROPIC AND CLIMATE CHANGES. ENVIROMIS-2006 - NELDA WORKSHOP 4

  5. NELDA / POSTEL / SIRS IS POSTEL POSTEL THE EUROPEAN ELEPHANT ? THE EUROPEAN ELEPHANT ? IS ♦ It is meaningless to consider POSTEL in itself without taking into account the European GMES initiative. ♦ Together with GALILEO, GMES is one of the two pillars of the European Space Policy. But GMES is an integrated initiative that obviously requires space observations, in situ measurements, modelling - not just a space initiative. ♦ GMES is a joint initiative of the European Commission and ESA, plus national initiatives. ♦ GMES plans switching to an operational phase starting in 2008 through the so-called GMES Service Elements (GSE). ENVIROMIS-2006 - NELDA WORKSHOP 5

  6. NELDA / POSTEL / SIRS IS POSTEL POSTEL THE EUROPEAN ELEPHANT ? THE EUROPEAN ELEPHANT ? IS ♦ One of the GSE’s will be dedicated to land use and land cover. ♦ Within such a framework, France, Belgium (VITO) and Portugal (EUMETSAT SAF Land) decided to join their forces in order to set up an operational service under the GMES label. ♦ POSTEL has to be understood now as the development phase of such an operational service. ENVIROMIS-2006 - NELDA WORKSHOP 6

  7. NELDA / POSTEL / SIRS : IS POSTEL POSTEL THE EUROPEAN ELEPHANT ? THE EUROPEAN ELEPHANT ? IS POSTEL is made up of three layers: ♦ Upstream: Scientific Expertise Centres (research orgazations that define space missions and relevant derived products) ; ♦ CSP is the Core Service for biogeophysical Parameters. It develops processing chains and generates, archives & circulate products ; ♦ Worldwide users’ community (interdisciplinary studies of surface; carbon, water and energy cycles; food security management; monitoring of land cover changes) . ENVIROMIS-2006 - NELDA WORKSHOP 7

  8. NELDA / POSTEL / SIRS : IS POSTEL POSTEL THE EUROPEAN ELEPHANT ? THE EUROPEAN ELEPHANT ? IS To-day , POSTEL is a potfolio of projets that contribute to the CSP and can be classified into three categories 1 - R & D PROJECTS ♦ CYCLOPES aims at developing and validating biophysical products (abedo, LAI, FAPAR, vegetation cover) from various wide-swath sensors (AVHRR, VEGTATION, POLDER, MERIS). The products proved useful to detecting and categorizing land use changes, and assessing C fluxes ENVIROMIS-2006 - NELDA WORKSHOP 8

  9. NELDA / POSTEL / SIRS : IS POSTEL POSTEL THE EUROPEAN ELEPHANT ? THE EUROPEAN ELEPHANT ? IS 1 - R & D PROJECTS (Ctd) ♦ The AMMA project addresses the African Monsoon. POSTEL provides AMMA with low-resolution continental products derived from EUMETSAT and intended to hydrologists, ecology experts, atmosphere scientists. ♦ The VALERI project aims at intercomparing products derived from various sensors and algorithms and assessing the absolute accuracy of biophysical products delivered by the POSTEL CSP. Validation is performed through a network of in-situ measurements distributed over the Earth surface. ENVIROMIS-2006 - NELDA WORKSHOP 9

  10. NELDA / POSTEL / SIRS : IS POSTEL POSTEL THE EUROPEAN ELEPHANT ? THE EUROPEAN ELEPHANT ? IS 2 – GMES pre-operational projects ♦ GEOLAND is an integrated project planned to be the backbone of GMES-related operational services. It plans to prove the pre-operational capacities of two Core Services : (1) generic land cover and (2) biogeophysical parameters, divided into six downstream services among which three regional (European) services and three global services. Products include LAI, vegetation cover, water bodies, FAPAR, albedo, incoming radiance, land surface temperature & moisture, burnt areas, rainfall ENVIROMIS-2006 - NELDA WORKSHOP 10

  11. NELDA / POSTEL / SIRS : IS POSTEL POSTEL THE EUROPEAN ELEPHANT ? THE EUROPEAN ELEPHANT ? IS 2 – GMES pre-operational projects ♦ GLOBCOVER aims at taking advantage of the moderate resolution, hyperspectral MERIS instrument on board ENVISAT to derive 250 m resolution land cover maps over the whole world updated on a regular basis. ♦ VGT4AFRICA aims at distributing products derived from the VEGETATION instrument in Africa. ENVIROMIS-2006 - NELDA WORKSHOP 11

  12. NELDA / POSTEL / SIRS : IS POSTEL POSTEL THE EUROPEAN ELEPHANT ? THE EUROPEAN ELEPHANT ? IS 3 – Spatial projects ♦ POLDER instruments measure multidirectional and polarisation radiance in the visivle and NIR domain. They are/were flown on bord ADEOS-1, 2 and PARASOL. POSTEL delivers land surface parameters to the POLDER Production Centre. Such products as directional albedo, NDVI, LAI, FVC, FAPAR, BDRF database are made available step by step through that channel. ♦ VENµS is a franco-israeli project. This satellite will monitor dedicated test sites though 12 channels. Deriving biogeophysical products is also in the POLDER mission. ENVIROMIS-2006 - NELDA WORKSHOP 12

  13. NELDA / POSTEL / SIRS : IS POSTEL POSTEL THE EUROPEAN ELEPHANT ? THE EUROPEAN ELEPHANT ? IS A Postel product: fraction of vegetation cover. CYCLOPES project, VEGETATION sensor, July/August 2003 synthesis. ENVIROMIS-2006 - NELDA WORKSHOP 13

  14. NELDA / POSTEL / SIRS : IS POSTEL POSTEL THE EUROPEAN ELEPHANT ? THE EUROPEAN ELEPHANT ? IS POSTEL, GMES and NELDA ♦ From a technical point of view, the POSTEL products are well suited to ease the work of NELDA scientists and /or to be directly used by them. GEOLAND and GLOBCOVER appaer as most promising. ♦ From a scientific point of view, individual researchers involved in POSTEL could be interested in NEESPI/NELDA if they get an attractive scientific return. Formal bilateral relationship with research institutions should be considered. ENVIROMIS-2006 - NELDA WORKSHOP 14

  15. NELDA / POSTEL / SIRS : IS POSTEL POSTEL THE EUROPEAN ELEPHANT ? THE EUROPEAN ELEPHANT ? IS POSTEL, GMES and NELDA (Ctd) ♦ From an operational point of view, the CPS is planned to rank among the GMES/GSE that will routinely provide scientifically labelled products. ♦ From a political point of view, GMES is highly ranked in the EC and ESA policy and may be seen as a formal contribution to NEESPI/NELDA. This has to be negotiated by and with the ‘proper’ authorities. ENVIROMIS-2006 - NELDA WORKSHOP 15

  16. NELDA / POSTEL / SIRS : IS SIRS SIRS THE SIBERIAN ELEPHANT ? THE SIBERIAN ELEPHANT ? IS ♦ SIRS has been initiated and developed for (at least) two years by top-level Russian scientists and supported by some Western Europe institutions (Max Planck Institut, Hamburg; Medias-France). An « initiative group » has been set up and endorsed. ♦ SIRS has been developed keeping in mind the guidelines of ESS-P Integrated Regional Studies. ENVIROMIS-2006 - NELDA WORKSHOP 16

  17. NELDA / POSTEL / SIRS : IS SIRS SIRS THE SIBERIAN ELEPHANT ? THE SIBERIAN ELEPHANT ? IS ♦ A consensus about guidelines that can be considered both as a strategic and a scientific plan has been reached by an in-house work of the Russian scientific community and endorsed during two dedicated workshops. ♦ So, SIRS can and should be considered as THE federative force that can bring together regional scientists supported at national & european levels and the projects that they are leading / will lead into an actually integrated and comprehensive ‘study’. ENVIROMIS-2006 - NELDA WORKSHOP 17

  18. NELDA / POSTEL / SIRS : IS SIRS SIRS THE SIBERIAN ELEPHANT ? THE SIBERIAN ELEPHANT ? IS Four key initial focussing activities were defined: ♦ Quantification of the terrestrial biota full greenhouse gas budget, ♦ Monitoring and modelling of regional climate change impact. ♦ Development of SIRS information-computational infrastruicture, ♦ Development of an anticipatory regional strategy of adaptation to and mitigation of the negative consequences of global change.
