15 June 2016 - The 14th JCSDA Technical Review Meeting and Science Workshop on Satellite Data Assimilation took place on May 31 - June 2, 2016. The meeting, which was coordinated by NRL, was held at the Moss Landing Marine Laboratories in Moss Landing, CA. The workshop posters and presentations can be found online on the meeting webpage.

SMAP Data Assimilation at the GMAO

02.25.2016
The NASA Soil Moisture Active Passive (SMAP) mission has been providing L-band (1.4 GHz) passive microwave brightness temperature (Tb) observations since April 2015. These observations are sensitive to surface (0-5 cm) soil moisture. Several of the key applications targeted by SMAP, however, require knowledge of deeper-layer, "root zone" (0-100 cm) soil moisture, which is not directly measured by SMAP. The NASA Global Modeling and Assimilation Office (GMAO) contributes to SMAP by providing Level 4 data, including the Level 4 Surface and Root Zone Soil Moisture (L4_SM) product, which is based on the assimilation of SMAP Tb observations in the ensemble-based NASA GEOS-5 land surface data assimilation system. The L4_SM product offers global data every three hours at 9 km resolution, thereby interpolating and extrapolating the coarser- scale (~40 km) SMAP observations in time and in space (both horizontally and vertically).
