SnowEx23 Airborne SWESARR Backscatter Intensity Raw V001
Listed in NASA Earthdata CMR
This data set contains raw airborne microwave observations from the Goddard Space Flight Center SWESARR (Snow Water Equivalent Synthetic Aperture Radar and Radiometer) instrument collected during the SnowEx 2023 field campaign in Alaska.
Description
Data collection occurred over 10 microsecond intervals along a ~3 minute flight line using three frequencies (9.65, 13, and 17 GHz) in two polarization modes (VV and VH). All of the data files were acquired over a 7-day flight campaign in March 2023 and a 10-day flight campaign in October 2023.
Available data include measured complex backscatter in both in-phase and quadrature binary formats, along with supporting metadata.
