Autonomous phase sensitive radar on Sorsdal Glacier 2017-2019
Listed in NASA Earthdata CMR
Description
Autonomous phase sensitive radar (ApRES) installation at sites S02 and S04 on Sorsdal Glacier Locations: S02 (68.70774 S, 78.101115 E) and S04 (68.70995 S, 78.214617 E) Installation dates: S02 (17th Jan 2017) and S04 (17th Feb 2017) Data retrieval: 24th December 2018 Measurement interval: 2 hr ApRES phase-sensitive radar is a low-power, light-weight instrument developed in a collaboration between BAS and University College London.
It is a 200-400 MHz FMCW radar, with a 1-second chirp, run by controller. The radar’s transmit aerial and receive aerial are spaced 1.5 meters each side of the electronics box and mounted at the ice surface in a plywood box. The radar was set to record thickness every 2 hrs and this has been converted to a timeseries of thickness change.
