PHOENIX — Researchers examining data produced by small satellites launched in 2016 to track ocean winds were surprised the mission produced valuable information on soil moisture and flooding.
NASA's Cyclone Global Navigation Satellite System, a constellation of eight 30-kilogram satellites built by the Southwest Research Institute and the University of Michigan, observed the Amazon River basin in far more detail than NASA's Soil Moisture Active Passive mission even when SMAPs radar still worked.

Clara Chew of the University Corporation for Atmospheric Research published in August Amazon River basin flood maps with observations from SMAP's radar and radiometer as well as CYGNSS. SMAP's radiometer offered 30-kilometer resolution and its radar three-kilometer resolution compared with roughly 500-meter resolution for CYGNSS.
CYGNSS is good at picking up soil moisture near the surface and revealing flooding, Chew said at the American Meteorological Society conference here.
