The scientists analyzed a drought severity index and two
soil moisture data sets from 17 climate models that were run for both emissions scenarios.
The study, published today in Science, used 9 years
of soil moisture data from NASA's venerable Aqua satellite along with data from a network of rain gauges.
NASA scientists used tree rings to understand past droughts and climate models
incorporating soil moisture data to estimate future drought risk in the 21st century.
Version 3 Aquarius L2 Swath Single
Orbit Soil Moisture data are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).
Version 3 Aquarius L3 Gridded 1 -
Degree Soil Moisture data are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).
The ESA CCI
soil moisture data show a strong similarity with related terrestrial water cycle components such as terrestrial water storage, precipitation, the self - calibrating PDSI, and terrestrial evaporation.
Sheffield, J. & Wood, E. F. Characteristics of global and regional drought, 1950 — 2000: analysis of
soil moisture data from off - line simulation of the terrestrial hydrologic cycle.
To figure out how much anthropogenic warming contributed to California's drought, Park Williams and a team at Columbia University's Earth Institute looked
at soil moisture data in various parts of the state for every month from 1901 through 2014.
Scientists are hoping that newer satellites, like Europe's Soil Moisture and Ocean Salinity or NASA's Soil Moisture Active Passive, can start to accumulate long - time series
of soil moisture data.
Murry Salby who is suggesting that ocean and
soil moisture data shows that the observed rise in atmospheric CO2 might well be entirely from natural causes and Roy Spencer who suggests that variations in oceans and sun affecting global cloudiness make it impossible to verify the sign of the climate system response to more CO2 in the air.
A robot to muster livestock, control weeds and send pasture quality and
soil moisture data to the farm computer is no longer a fantasy.
The soil moisture data are standardized to the Palmer Drought Severity Index and are deviations from the 20th century average.

See below for a discussion how this affects the comparability of
the soil moisture data records.
Limitations of
soil moisture data and mechanisms in the computer models invalidate any output they produce, but it's only one of many.
