It was reduced to 240 km, then 235 km, and since May 31 to 225 km. End of life is predicted in November 2013.  Mission goals have been reached and in some cases outperformed.  4 th generation gravity field model was released in March.  5 th release is expected around mid-2014 GOCE – The Gravity-field and Ocean steady-state Circulation Explorer

Current users: NOAA/NESDIS, CMC Canada and US Navy  RFI situation continues to improve  Performance goals (4% volumetric soil moisture, <1 psu) are within reach SMOS – Soil Moisture and Ocean Salinity First merged global maps of soil moisture (August 2011) and sea surface salinity (August 2010), morning orbits. © CESBIO, IFREMER, CATDS

SMOS, A VERSATILE MISSION – HURRYCANE SANDY Aircraft and SMOS wind speeds showed excellent agreement
