Soil Moisture Data

A series of Soil Moisture Experiments (SMEX) were conducted from 2002 to 2005 address a broad range of science and instrument questions related to soil moisture remote sensing. The objectives of the experiments were to provide data sets for studies of hydrologic processes and land/atmosphere interactions, validate spaceborne soil moisture measurements (such as from the AMSR-E instrument), and evaluate new instrument technologies.

AMSR-E validation studies linked to SMEX are designed to evaluate the accuracy of AMSR-E soil moisture data. Specific validation objectives include: assessing and refining soil moisture algorithm performance; verifying soil moisture estimation accuracy; investigating the effects of vegetation, surface temperature, topography, and soil texture on soil moisture accuracy; and determining the regions that are particularly useful for AMSR-E soil moisture measurements.
