Fieldextra

Fieldextra extracts gridded data in GRIB format and writes them into GRIB or ASCII formatted files. It contains capabilities to extract subdomains or point data for a list of locations, and to calculate derived quantities.

Fieldextra is a generic tool to manipulate NWP model data and gridded observations; simple data processing and more complex data operations are supported, for example: selecting data satisfying some complex condition, comparing or merging multiple fields, horizontal and vertical re-gridding, computation of regional means, computation of stability indices, computation of neighbourhood and EPS probabilities. The resulting values are produced in ASCII or GRIB1 format; a rich choice of output is proposed.

This page only contains information on those versions of Fieldextra that have been made operational at MeteoSwiss.
