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

Thursday, April 22, 2021

The L-band radar aboard the JSC G-III has successfully completed the spring 2021 Delta-X campaign.  In all we conducted 9 flights over 3 different regions of Atchafalaya Bay in Louisiana between 27 March and 18 April totaling 51.2 hours.  These nine flights were flown over a range of tidal conditions to capture the wetlands at different water level heights.  The Delta-X science team will be using UAVSAR phase difference imagery from adjacent flight lines to determine water level change in wetlands.  This information, along with other airborne and in-situ data, will help them calibrate their hydrology and sediment transport model to predict long-term soil accretion at the delta under projected relative sea level rise, river discharge, and sediment supply.
