Description

This data set provides Arctic summer sea ice heights acquired using the Leica Chiroptera 4X (CHIR) airborne lidar system. The near-infrared (NIR) lidar data were acquired during a July 2022 calibration/validation airborne campaign to evaluate the positional accuracies of NASA’s ICESat-2 ATLAS measurements.
