WATER-HM activities: CNES programmatic status Prepared by Eric Thouvenot & Pascale Ultré-Guérard Direction for Strategy and Programs - CNES

WATER-HM workshop, Paris, 01/02/08 Earth observation programme (multilateral) ■Phase E  Déméter  Jason  SPOT, Végétation  Parasol,  Calipso  Iasi/Metop ■Phases C/D  Jason-2 (juin 2008)  Smos (nov 2008)  Megha-Tropiques (2009)  Pléiades (2009)  Vén  s (2010) : pb de filtres  SARAL/Altika ( )  Swarm (2010) ■Phase A  SIFTI  SWIM/CFOSAT

WATER-HM workshop, Paris, 01/02/08 Pre-Phase A ■MTG ■Vegetation-Gap Filler with ESA/DTEC and Belgium ■Water/SWOT (coop. NASA) ■E-Corce (constellation of satellites HR) ■Trade Off LEO-GEO for coastal regions and risk management (coop. JAXA) ■Infra red sounder for post EPS (IASI F/O, coop. Eumetsat) ■3MI (Multiviewing Multichannel Multipolarization Imager) (Polder F/O) ■TIR MISTIGRI (study of vegetation cycle : high resolution and high revisit, coop. Spain) ■Lidar for altimetry and bathymetry ■Hyperspectral ■Microméga (Grace F/O) ■CO2 : Minicarb ■Pollution from geostationnary orbit

WATER-HM workshop, Paris, 01/02/08 WATer Elevation Recovery & Hydrosphere Mapper Mission combining research needs associated to hydrology and oceanography : mapping of water level for rivers, lakes, and oceans (including coasts) Principle : Wide-swath interferometric, Ka- band altimeter Cooperation scheme : TBD (NASA/CNES/NOAA/…) Status : -Phase 0 underway -Phase A possible in mid Launch : 2015+

WATER-HM workshop, Paris, 01/02/08 ■Exchange of letters between NASA&CNES :  Agreement on conducting a cooperative preliminary study about WATER-HM  In the spirit and in the continuation of 20+ years of cooperation in space altimetry  Agreement to constitute a common Science Working Group  Points of Contact for Programmatics and Science designated ■CNES phase 0 study in progress, fully funded ■SWG created, Terms Of Reference agreed Phase 0 status

WATER-HM workshop, Paris, 01/02/08 Follow-on activities ■CNES/NASA and CNES/NOAA meetings at CEO/Administrator level => WATER-HM is a high priority in France/US space cooperation ■Formal review of proposals at CNES end of September, 2007 => WATER-HM ranked first for entering phase A in 2008 => CNES will be able to fund phase A in 2008/2009 :  dedicated project team  industrial & science activities ■Conditions/constraints to enter phase A in 2008 :  Phase 0 has to be ok  no showstopper  science goals & requirements in agreement with phase 0 design(s)  Cooperation/coordination with NASA to be discussed :  CNES does not intend to perform the whole set of phase A activities  Preliminary responsibility/task sharing to be discussed
