SIMPL Field Campaign in Greenland

The Ice, Cloud and land Elevation Satellite-2 (ICESat-2) mission flew a laser altimeter instrument aboard an aircraft over Greenland for three weeks in August. The instrument, called the Slope Imaging Multi-polarization Photon-counting Lidar, or SIMPL, took height measurements with both a red and a green laser, which will allow scientists to determine whether green light behaves differently when it reflects off different types of snow and ice.

The Greenland SIMPL campaign is part of a multi-year, pre-launch effort to find out as much as possible about how lasers and photon detectors similar to those on ICESat-2 measure ice sheet height, and what that photon data looks like.
