SMAP Satellite Monitors Texas Drought NASA”s Soil Moisture Active Passive satellite — SMAP — gives Texas water agencies critical information for managing the lone star state”s limited water. The rapid intensification of Hurricane Harvey was observed by the radiometer instrument aboard NASA’s Soil Moisture Active Passive (SMAP) satellite. Animations of the global sea surface salinity and soil moisture products have been released, featuring both a global view and a north polar view.
Results of a study reveal that SMAP soil moisture retrievals are generally better than AMSR2 soil moisture data. NASA scientists are auditioning the radar aboard a European satellite to see how well it stands in for the radar that failed aboard the U.S. space agency’s newly launched Soil Moisture Active Passive (SMAP) satellite in July.
SMAP will be working with the Texas Soil Observation Network to help water managers in Texas. NASA’s innovative soil moisture mapper, a new environmental satellite launching in January, has been fueled up for blastoff from Vandenberg Air Force Base in California.
Scheduled for launch on Jan. 29, 2015, NASA’s Soil Moisture Active Passive (SMAP) instrument will measure the moisture lodged in Earth’s soils with an unprecedented accuracy and resolution. The instrument’s three main parts are a radar, a radiometer and the largest rotating mesh antenna ever deployed in space.
