This data set contains C-band radar data collected during the NASA SnowEx 2023 Alaska field campaign between 08 March 2023 to 15 March 2023. Data was acquired from two study areas near Fairbanks, Alaska using a multi-polarization radar affixed to sled-mounted tower. The study sites (Caribou Poker Creek watershed and Farmer’s Loop/Creamer’s Field) are boreal forest and wetland environments. Data was also collected from a school adjacent to Farmer’s Loop, to record data from man-made surfaces (i.e., concrete and cultivated grass.)
