New data set release: ATLAS/ICESat-2 ATL03 Ancillary Masks, Version 1

The ATLAS/ICESat-2 ATL03 Ancillary Masks, Version 1 is an ancillary ICESat-2 data set that contains four static surface masks (land ice, sea ice, land, and ocean) provided to reduce the volume of data required to be processed for each surface-specific along-track data product. For example, the land ice surface mask directs the ATL06 land ice algorithm to consider data from only those areas of interest to the land ice community. Similarly, the sea ice, land, and ocean masks direct ATL07, ATL08, and ATL12 algorithms, respectively.  A detailed description of all four masks can be found in section 4 of the Algorithm Theoretical Basis Document (ATBD) for ATL03 linked under technical references.
