Delivery formats

NetCDF-4 is the baseline format for the FCI, LI and IRS instrument level 1 dataset generation and level 2 geophysical products. NetCDF-4 offers a number of advantageous features, including:

  • Ability to cope with large dataset sizes — ~7 Gbytes for Full Disc archived dataset for MTG compared to the current ~220 Mbytes.
  • Datasets are self describing.
  • Groups allow potential for easier subsetting.

Selected products will also be available in BUFR, GRIB and other formats where required to continue an existing service.


Algorithm Theoretical Basis Documents (ATBD) and product guides

Algorithm Theoretical Basis Documents (ATBD) describe the algorithm theoretical basis for the derivation of Level 2 MTG products, providing an insight into product retrieval schemes. ATBDs usually contain a short overview over the relevant MTG instrument characteristics, followed by a general approach towards the geophysical parameter of interest, and detailed description of the underlying algorithm of the product — its physical basis, the required input data, and a more detailed description of the product retrieval method. Practical application of the algorithm, with a few results, may also be contained, together with relevant references.

Product Guides serve as a non-extensive overview of the particular products. Such guides normally give the utilisation context and a description of the product, product specifications (e.g. inputs, outputs, coverage, limitations), product illustration (e.g. case studies), and associated resources and reference documents that might further assist users.
