Aircraft radar that sees through clouds (UAVSAR)

UAVSAR_POLSAR_STOKES
land NASA ASF Level 1 active
In plain English

What it measures. Radar scenes of the land surface that can see through clouds and work day or night, capturing detailed information about surface texture and structure.

How it's made. Collected by the UAVSAR radar instrument flown on a G-III aircraft, processed into polarized radar ('PolSAR Stokes') scene data.

How & where you'd use it. Aircraft radar like this is used to map terrain, vegetation, and surface change in detail regardless of weather or daylight; the abstract is very brief on specifics.
