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-2008-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
