Description

ATL11 provides spatially organized time series of land-ice surface heights and ice-shelf locations where ICESat-2 operates in repeat-track mode (i.e., for polar ice), along with parameters useful in determining whether each height estimate is valid or a result of potential errors. ATL11 is derived from the ATLAS/ICESat-2 L3A Land Ice Height product (ATL06) and intended primarily as an input for higher-level gridded products.

Version Description

-Matched valid min/max to data type for all datasets -Updated atlas_meta and atl11_qa_util to latest versions -Corrected root file level title and description for ATL11 -Removed h_corr_CrossOver from browse plots -Removed crossing_track_data group from ATL11 -Implemented additional checks to filter ATL06 anomalies -Used least squares in reference surface for validity check
