Soil moisture is retrieved over land targets on the descending (AM) SMAP half-orbits when the SMAP spacecraft is travelling from North to South, while the SMAP instruments are operating in the nominal mode. The L3_SM_A product represents soil moisture retrieved over the entre UTC day. Retrievals are performed but flagged as questionable over urban areas, mountainous areas with high elevation variability, and areas with high ( > 5 kg/m**2) vegetation water content; for retrievals using the high-resolution radar, cells in the nadir region are also flagged. Retrievals are inhibited for permanent snow/ice, frozen ground, and excessive static or transient open water in the cell, and for excessive RFI in the sensor data. true -180 180 -85.044502258300781 85.044502258300781 2015-07-07T00:00:00.000Z 2015-07-07T23:59:59.999Z attribute soil_moisture Percent of Sigma0s that are within the Acceptable Range.
