The L3_SM_P 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 ( &gt; 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.</gco:CharacterString>

<gmi:description>
<gco:CharacterString>The SMAP observatory houses an L-band radiometer that operates at 1.414 GHz and an L-band radar that operates at 1.225 GHz. The instruments share a rotating reflector antenna with a 6 meter aperture that scans over a 1000 km swath. The bus is a 3 axis stabilized spacecraft that provides momentum compensation for the rotating antenna.</gco:CharacterString>

retrieved over land targets on the
descending (AM) and ascending (PM) SMAP half-orbits,
while the SMAP instruments are operating in the nominal mode. 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,
