F17: Remote Sensing of Land and Sea at L band (1)

Friday, August 22  13:40-15:40,  Room #4

L-band is important for remote sensing of soil moisture and ocean salinity, two variables important for understanding the global water cycle and ocean dynamics. There are soon to be three satellite missions with L-band sensors devoted to measuring these variables: The ESA Soil Moisture and Ocean Salinity (SMOS) mission and the NASA Aquarius/SAC-D mission, which are already in orbit and NASA’s Soil Moisture Active Passive (SMAP) mission scheduled for launch in the Fall of 2014. The latter two missions employ both passive (radiometer) and active (radar) sensors at L-band. This session will focus on results and status of these three missions but will also entertain new applications (e.g. application to the cryosphere such as L-band monitoring of sea ice) and active/passive synergy at L-band. Suggested topics are: 1) Results from Aquarius: Sea Surface Salinity; Soil Moisture, Remote Sensing Algorithm. 2) Results from SMOS: Ocean Salinity; Soil Moisture, Remote Sensing Algorithm. 3) Status of SMAP: Instrument Algorithm and plans, Active/Passive Synergy: Disaggregation using radar, Enhanced products. 4) New Applications: Sea Ice extent; Sea Ice Thickness, Drought indices, Root zone soil moisture.
