Short Name:

IceBridge Preliminary ATM L1B Elevation and Return Strength V001

This data set contains preliminary spot elevation measurements of Arctic sea ice and Greenland ice surface for four days in April 2019, acquired using the NASA Airborne Topographic Mapper (ATM) instrumentation. The data were collected as part of Operation IceBridge funded aircraft survey campaigns. Note: These preliminary data were released for the sole purpose of ICESat-2 performance assessment and algorithm validation. They have not undergone the usual refinement and quality control of the IceBridge ATM L1B Elevation and Return Strength (ILATM1B) product and may contain errors. Once the final data products for these days are available at NSIDC, users should download the ILATM1B data.
