Greenland Ice Surface Elevations from NASA ATM Airborne Lidar, Version 1

Scanning laser altimeters were flown over the Greenland icesheet during late spring or early summer from 1993 to 1999. Flights spanned the entire icesheet, sampling interior and coastal regions and several outlet glaciers. The data provided here are condensed from the original scanning lidar measurements to roughly one measurement per 75 m along the flight track, by fitting a plane to a set of points within a 70 meter by 150 meter subset. Each record in the resulting data set includes location, ellipsoid elevation, surface slope, and an RMS surface roughness. Flights from 1993 and 1994 were repeated in 1998 and 1999 to provide a measurement of the ice elevation change over a five-year period.
