Abstract:
<p>Each Level-1A (L1A) granule incorporates all radiometer data downlinked from the Soil Moisture Active Passive (SMAP) spacecraft for one specific half orbit. The data are scaled instrument counts of the following:</p>
<ul>
<li>The first four raw moments of the fullband channel for both vertical and horizontal polarizations</li>
<li>The complex cross-correlations of the fullband channel</li>
<li>The 16 subband channels for both vertical and horizontal polarizations</li>
</ul>
