CryoTempo-EOLIS-Product-Handbook
This CryoTEMPO Product Handbook describes the operational products, a point cloud product containing the elevations derived using a swath processing algorithm and a gridded product with elevations at regularly spaced points on a grid. The operational products provide analysis ready data to a wider community of scientists rather than individual altimetry experts.

Envisat AATSR 4th Reprocessing data now available
The 4th Reprocessing of the AATSR instrument L1B data stemming from the Envisat satellite have now been released to users following successful quality assessment.
Data - Data Description
Envisat AATSR L1B Brightness Temperature/Radiance [ENV_AT_1_RBT]
- AATSR Full Resolution land and ocean cover image of the Iberian Peninsula from 28 October 2006 AATSR Full Resolution land cover image of the Iberian Peninsula from 28 October 2006. The Envisat AATSR Level 1B Brightness Temperature/Radiance product (RBT) contains top of atmosphere (TOA) brightness temperature (BT) values for the infra-red channels and radiance values for the visible channels, on a 1-km pixel grid. Values for each channel and for the nadir and oblique views occupy separate NetCDF files within the Sentinel-SAFE format, along with associated uncertainty estimates. Additional files contain cloud flags, land and water masks, and confidence flags for each image pixel, as well as instrument and ancillary meteorological information. This AATSR product [ENV_AT_1_RBT] in NetCDF format stemming from the 4th AATSR reprocessing, is a continuation of ERS ATSR data and a precursor of Sentinel-3 SLSTR data. It has replaced the former L1B product [ATS_TOA_1P] in Envisat format from the 3rd reprocessing. Users with Envisat-format products are recommended to move to the new Sentinel-SAFE like/NetCDF format products. The 4th reprocessing of ENVISAT AATSR data was completed in 2022; the processing updates that have been put in place and the expected scientific improvements have been outlined in full in the User Documentation for (A)ATSR 4th Reprocessing Products.
