Glacier surface GNSS measurements at Volcán Sollipulli, Chile, in February 2011

Glacier surface elevation measurements of the caldera glacier of Volcán Sollipulli. Data was gathered in February 2011 along three tracks across the glacier using differential GNSS with a base station installed on bedrock nearby. Measurements were made for every 2 m along these tracks. The accuracy of each measurement is estimated to be better than 20 cm. Measurements are provided in geographic coordinates (WGS84) with altitudes as ellipsoidal heights.
