CM SAF R TOOLBOX

The CM SAF R TOOLBOX is an easy-to-use tool to prepare, analyze and visualize CM SAF NetCDF data. The Toolbox comes as part of the cmsaf R-package, which is a collection of more than 100 functions for analysis and manipulation of CM SAF NetCDF formatted data. The CM SAF R Toolbox is based on an R-shiny graphical user interface, which guides through all options. Thus, no R or scripting experience is needed.

Auxiliary Data

The usage of 'bluemarble' quicklooks requires additional data, which are too large for the official cmsafvis R-package on CRAN. These data include longitude and latitude coordinates for the native Meteosat Second Generation (MSG) grid and a 'bluemarble' background image. To use this option for CLAAS quicklooks of instantaneous data, just set the keywords 'bluemarble' (true / false) and / or sysdata (path to sysdata.rda) in the configuration file (e.g., 'C:\Users\username\Documents\R\win-library\4.1\cmsafvis\extdata\quicklook_config.yml').

Bluemarble auxiliary data

In case that a question or problem can not be solved by help of the manual or the cmsaf R-package documentation contact the CM SAF User Help Desk (contact.cmsaf@dwd.de).
