Additional parameters include the beginning and end of the transect, transect length, and center of transect. ATL22 is derived from ATLAS/ICESat-2 L3A Along Track Inland Surface Water Data (ATL13).VIEW RELATED INFORMATIONhttps://nsidc.org/sites/default/files/documents/user-guide/atl22-v004-userguide.pdfATLAS/ICESat-2 L3B Mean Inland Surface Water Data, Version 4 User GuideGET DATAhttps://nsidc.org/data/data-access-tool/ATL22/versions/4/Data Access ToolGET DATAhttps://search.earthdata.nasa.gov/search/granules?p=C3824617301-NSIDC_CPRDEarthdata SearchGET DATAhttps://cmr.earthdata.nasa.gov/virtual-directory/collections/C3824617301-NSIDC_CPRDHTTPSGET DATAhttps://earthaccess.readthedocs.io/en/stable/earthaccessCEOS IDN DIFVERSION 9.92025-10-302026-02-12NSIDCVersion Summary-Version 4 of this data set was derived from ATL13 v7.
-Added calculation and output of transect mean maximum likelihood alpha
-Added sseg_length and sseg dist_from _eq
-Calculated the along-track observed linear slope and accompanying root mean squared error
-Defined process for fitting heights during along-track slope calculation
-Added detrend-based along-track mean slope and ATL13 orthometric height distribution skew and kurtosis
-Turned on calculation of along-track slope for lakes and reservoirs; added language for exclusion of invalid values in mean slope calculatio
-Added transect mean azimuth calculation and output; reversed 0/1 on/off assignments used for along_trk slope_calc array to match convention used for previous parameters
-For skewness and kurtosis calculations, added minimum filtered short segment requirements, controls based on water body type, and clarification to use bias-corrected results
-Turned on calculation of linear fit along-track slope for riversNSIDCMinor VersionNSIDCCurrent Version1NSIDCSpatial Reference SystemsEPSG:4326WGS 84NSIDCLevel of ServiceComprehensiveNSIDCFull Dataset CitationJasinski, M.
