What is the Cryosphere?
When scientists talk about the cryosphere, they mean the places on Earth where water is in its solid form, frozen into ice or snow. Read more ...
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.
