cmsaf (version 2.0.1)

Tools for CM SAF NetCDF Data

Description

The Satellite Application Facility on Climate Monitoring (CM SAF) is a ground segment of the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) and one of EUMETSATs Satellite Application Facilities. The CM SAF contributes to the sustainable monitoring of the climate system by providing essential climate variables related to the energy and water cycle of the atmosphere (). It is a joint cooperation of eight National Meteorological and Hydrological Services. The 'cmsaf' R-package provides a collection of R-operators for the analysis and manipulation of CM SAF NetCDF formatted data. The 'cmsaf' R-package is tested for CM SAF NetCDF data. Other CF conform NetCDF data should be applicable, but there is no guarantee for an error-free application. The 'cmsaf' R-package includes a 'shiny' based interface for an easy application of the 'cmsaf' package operators and the preparation and visualization of CM SAF NetCDF data. CM SAF climate data records are provided for free via (). Detailed information and test data are provided on the CM SAF webpage ().
