gnss-ir derived accumulation history at the GNSS sites LTHW, UTHW, and KHLR maintained by unavco and the polenet team.

Abstract

Accumulation time series were determined using GNSS interferometric reflectometry and MCMC inverse methods. Sites include KHLR, LTHW, and UTHW long-term GNSS stations on the Thwaites and Kohler glaciers. Included are the daily reflector heights of the phase center of the GNSS reciever antenna derived from median filtering daily reflections from satellite azimuths below 7 degrees. Also included are the daily accumulation time series determined from reflector height change at the site of each receiver.
