Description

This data set contains land ice height changes and change rates for the Antarctic ice sheet and regions around the Arctic gridded at multiple spatial and temporal resolutions. The data are derived from the ATLAS/ICESat-2 L3B Slope-Corrected Land Ice Height Time Series product (ATL11).

Version Description

This version was derived from ATL11 v7 and includes the following changes: Added check on input data against most recent ATL14/15 product to provide an initial outlier flag; Added monthly-resolution files to the existing quarterly-resolution set; Revised file-naming convention; Changed group naming format within files; Refactored code for improved maintainability and more efficient use of computing resources.
