  "description": "This is the Land Ice Thematic Data Product (TDP) V1 resulting from the _$$ESA FDR4ALT project$$ https://www.fdr4alt.org/ and containing estimates of ice sheet surface elevation and associated uncertainties.\rThe collection covers data for three different missions: ERS-1, ERS-2 and Envisat, and based on Level 1 data coming from previous reprocessing (ERS REAPER and the Envisat V3.0) but taking into account the improvements made at Level 0/Level 1 in the frame of FDR4ALT (_$$ALT FDR$$ https://earth.esa.int/eogateway/catalog/fdr-for-altimetry).\rThe Land Ice TDP focuses specifically on the ice sheets of Greenland and Antarctica, providing these data in different files.\rFor many aspects, the Land Ice Level 2 and Level 2+ processing is very innovative:\r\rImproved relocation approach correcting for topographic effects within the beam footprint to identify the Point of Closest Approach \rHomogeneous timeseries of surface elevation measurements at regular along-track reference nodes.\rThe FDR4ALT products are available in NetCDF format. Free standard tools for reading NetCDF data can be used.\rInformation for expert altimetry users is also available in a dedicated NetCDF group within the products.\rPlease consult the _$$FDR4ALT Product User Guide$$ https://earth.esa.int/eogateway/documents/d/earth-online/fdr4alt-products-user-guide before using the data.\rThe FDR4ALT datasets represent the new reference data for the ERS/Envisat altimetry missions, superseding any previous mission data. Users are strongly encouraged to make use of these datasets for optimal results.",
