UAVSAR – Uninhabited Aerial Vehicle Synthetic Aperture Radar – Facility Instrument Suite

Tuesday, March 23, 2021

The L-band radar aboard the JSC G-III has successfully completed the last of the weekly SnowEx observations today (March 22).  In all we conducted 10 weekly observations, missing only one week in mid-February when extreme freezing temperatures in Texas causing widespread power outage throughout the state, where UAVSAR is currently based.  The UAVSAR processing team back at JPL has been generating polarimetric interferograms of data acquired on adjacent weeks.  Attached is an example interferogram over Lowman, Idaho of data acquired on February 3 and 10 respectively.  The interferometric phase maintained pretty high coherence over the 7-day temporal separation.  The color variation is a result of difference in snow accumulation between the mountain ridges and the valleys.
