    Release of new Envisat DORIS Precise Orbit data

    A new version of the Envisat Precise Orbit products has been generated by the Centre de Traitement Doris Poseidon (CTDP) using the Geophysical Data Records F standards (GDR-F). The new dataset (DOR_VOR_AX vF) is now available to users in Envisat format from the ESA dissemination service.

    RA-Characterisation-Data.pdf

    This document can be regarded as a first issue of the long-awaited RA Characterisation Database. It contains values for all parameters which have been requested, except for some special cases which will be explained later. It contains many other parameters as well. For example it also contains all the parameters used in the LRDPF (and referred to in ER-RP-DSF-SY-0007) except for the parameters forseen to be updated frequently, such as the barometric pressure field (which will come from ECMWF).

    Land Ice Thematic Data Product [ALT_TDP_LI]

    This is the Land Ice Thematic Data Product (TDP) V1 resulting from the ESA FDR4ALT project and containing estimates of ice sheet surface elevation and associated uncertainties. The 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). The Land Ice TDP focuses specifically on the ice sheets of Greenland and Antarctica, providing these data in different files. For many aspects, the Land Ice Level 2 and Level 2+ processing is very innovative: Improved relocation approach correcting for topographic effects within the beam footprint to identify the Point of Closest Approach Homogeneous timeseries of surface elevation measurements at regular along-track reference nodes. The FDR4ALT products are available in NetCDF format. Free standard tools for reading NetCDF data can be used. Information for expert altimetry users is also available in a dedicated NetCDF group within the products. Please consult the FDR4ALT Product User Guide before using the data. The 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.
