Data transformation services through NASA Earthdata Harmony are now available for Version 7 of 9 ATLAS/ICESat-2 data sets archived at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). Harmony allows users to subset NASA ESDIS data available in Earthdata Cloud to their specific spatial and temporal regions of interest. Users can access Harmony through the NASA Earthdata Search interface or programmatically via Harmony’s API or harmony-py Python library. Data processed by Harmony can be accessed directly in the cloud or downloaded to a local computer for further analysis.
