The NASA Soil Moisture Active Passive (SMAP) mission: Overview [PDF]
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010 The Soil Moisture Active Passive (SMAP) mission is one of the first Earth observation satellites being developed by NASA in response to the National Research Council's Decadal Survey [1]. Its mission design consists of L-band radiometer and radar instruments sharing a rotating 6-m mesh reflector antenna to provide high-resolution and high-accuracy ...

DOWNSCALING OF SMAP SOIL MOISTURE PRODUCT BY DATA FUSION WITH VIIRS LST/EVI PRODUCT [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021 Soil moisture is an essential variable of environment and climate change, which affects the energy and water exchange between soil and atmosphere. The estimation of soil moisture is thus very important in geoscience, while at same time also challenging ...

Controls on surface soil drying rates observed by SMAP and simulated by the Noah land surface model [PDF]
Hydrology and Earth System Sciences, 2018 Drydown periods that follow precipitation events provide an opportunity to assess controls on soil evaporation on a continental scale. We use SMAP (Soil Moisture Active Passive) observations and Noah simulations from drydown periods to quantify the ...

A reduced latency regional gap-filling method for SMAP using random forest regression
iScience, 2023 Summary: The soil moisture active/passive (SMAP) mission represents a significant advance in measuring soil moisture from satellites. However, its large spatial-temporal data gaps limit the use of its values in near-real-time (NRT) applications ...

Soil Moisture Active/Passive (SMAP) radiometer Subband calibration and calibration drift [PDF]
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016 The radiometer Subband calibration and calibration drift correction have been successfully used in the released radiometer L1B data product. Although their performances satisfy the requirements, they are still under continuing analysis to find their remaining uncertainty. The progress will be presented besides the current performance.
