(2020) Independent Digital Elevation Model of Greenland from GNSS-R data from TechDemoSat-1. Natural Environment Research Council doi:10.5285/783515b1-ac01-4615-a24c-629fe37a63a2 [Dataset]
Abstract
SGR-ReSI, TechDemoSat-1,Improved Digital Elevation Model (DEM) of the Greenland Ice Sheet derived from Global Navigation Satellite Systems-Reflectometry (GNSS-R). This builds on a previous study (Cartwright et al., 2018) using GNSS-R to derive an Antarctic DEM but uses improved processing and an additional 13 months of measurements. A median bias of under 10 m and root-mean-square (RMS) errors of under 166 m are obtained, as compared to existing DEMs. Funding was provided by NERC grant NE/L002531/1.,Gridded group delay altimetry from TechDemoSat-1's GNSS-R data collected between September 2014 and December 2018. For full details see Cartwright et al., 2020.,A median bias of under 10 m and root-mean-square (RMS) errors of under 166 m are obtained, as compared to existing DEMs.
