Project Title NSIT - Land Surface Moisture and
Water Budget Studies Using Microwave Remote
Sensing Principal Investigator Eni G. Njoku
(eni.g.njoku_at_jpl.nasa.gov)
Science issue Characterize land surface moisture
space/time variability and role in surface
fluxes Approach Evaluate space-based soil
moisture products compare with models and
in-situ data integrate current and near-future
satellite observations Satellite data AMSR-E,
TMI, ERS, SMOS, Aquarius Other data IGBP, SRTM,
SCAN, CPC, NARR Models GLDAS, NCEP, ECMWF Study
particulars Calibration, retrieval algorithms,
surface heterogeneity, vegetation sensitivity,
scaling
Project Status Year 1 2 (complete) Acquire
and process multi-sensor passive datasets
multiyear intercomparisons and evaluations over
U.S. Year 3 Global intercomparisons, active
(scatterometer) and passive datasets
variability, trends and statistics heterogeneity
and spatial scaling studies Year 4 5
Integrate surface moisture/water products and
analyses test applicability to surface flux
studies NEWS IP task - assessments for land
surface water
