The Soil Moisture Active Passive (SMAP) mission has engaged with GLOBE to obtain surface soil moisture measurements from student citizen scientists. These measurements will become part of SMAP’s calibration/validation effort. Gravimetric soil moisture measurements are the gold standard for this environmental variable, and these may be taken by almost anyone. Through GLOBE, the resulting data can be reported and archived and put to use by the SMAP Science Team.
SMAP scientists have indicated that measurements from clusters of 10 sites within a 10 km radius circle are particularly helpful....
