Surface elevations (digital elevation models and GPS data) for three ice rises (Blåskimen Land, Kupol Ciolkovskogo and Kupol Moskovskij) in Western Dronning Maud Land observed in 2012-14
This dataset provides surface elevations of three ice rises, Blåskimen Land (IRD), Kupol Ciolkovskogo (IRB) and Kupol Moskovskij (IRC), around the Fimbul Ice Shelf, in Western Dronning Maud Land. The digital elevation models (DEMs) were developed using kinematic GPS measurements tied to a local base...

The digital elevation models (DEMs) were developed using kinematic GPS measurements tied to a local base station on each ice rise. The DEMs are projected to a polar stereographic projection parallel to 71°S ([EPSG 3031](http://www.opengis.net/def/crs/EPSG/0/3031)). GPS data are provided in terms of WGS84 latitudes, longitudes, and heights above the ellipsoid. The DEM elevations are relative to the sea level; a local geoid height (13 m, [GOCE gravity product](https://earth.esa.int/web/guest/data-access/browse-data-products/-/article/goce-gravity-fields-5777)) was subtracted from the heights above the WGS84 ellipsoid. The data are provided in MATLAB (.mat) file format. For each ice rise the files are named such as ‘IRB_DEM.mat and ‘IRB_GPS.mat’: IRB_DEM.mat includes a struct-class variable. XX and YY show the coordinates, and ZZ shows elevations. All are in the unit of meters. IRB_GPS.mat include a struct-class variable. LAT and LON are decimal degrees, and Z is in meters. IRB_DEM.png shows the DEM in color and contours (10 m intervals) together with GPS tracks (white). It is plotted against a local coordinate, which is parallel to EPSG3031 but the origin is the summit of the ice rise. GPS data for IRD provided here include erroneous data that show (both positive and negative) spikes in the elevations; these data are outliers from adjacent data points, and in some cases the spike height reaches 5-10 m. These spikes appear near the summit and other places. Because the number of erroneous data points is quite small, these features do not significantly affect the DEM.

This dataset provides surface elevations of three ice rises, Blåskimen Land (IRD), Kupol Ciolkovskogo (IRB) and Kupol Moskovskij (IRC), around the Fimbul Ice Shelf, in Western Dronning Maud Land.
