  "description": "This is the Ocean Waves Thematic Data Product (TDP) V1 resulting from the _$$ESA FDR4ALT project$$ https://www.fdr4alt.org/ and containing Significant Wave Height estimates for the ERS-1, ERS-2 and Envisat missions.\rCompared to existing datasets, the Ocean Waves TDP demonstrates notable improvements in several aspects:\r\rGreat improvements for Envisat due to noise reduction from Adaptive retracker and High-Frequency Adjustment (HFA)\rAll variables are given at 5 Hz\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.",
