Evapotranspiration Everywhere, All the Time: Towards a Unified View From Earth Observation. [PDF]
This paper discusses the evolution and revolution of Earth observation for evapotranspiration (ET), as we advanced from the first Landsat satellite and development of ET models through the progression of increasingly higher resolution across international space agencies and commercial industry with increasing ET model sophistication, cloud computing ...

DOWNSCALING OF SMAP SOIL MOISTURE PRODUCT BY DATA FUSION WITH VIIRS LST/EVI PRODUCT [PDF]
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]
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
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 ...

Downscaling of SMAP Soil Moisture Using Land Surface Temperature and Vegetation Data
Remotely sensed soil moisture retrieved by the Soil Moisture Active and Passive (SMAP) sensor is currently provided at a 9-km grid resolution. Although valuable, some applications in weather, agriculture, ecology, and watershed hydrology require soil ...
