Deutscher Wetterdienst Hermann Asensio, DWD, COSMO Priority Project COLOBOC , Offenbach Software Requirements Specifications  explanation of the purpose and features of the External Parameter system

Deutscher Wetterdienst Hermann Asensio, DWD, COSMO Priority Project COLOBOC , Offenbach Software Requirements Specifications user requirements:  support of variable domains (including poles) on the earth  the output data should contain information on the processing software and input raw data (reproducibility)  the EXTPAR software system should be run from a shell  addition of further external parameter fields should be feasible

Deutscher Wetterdienst Hermann Asensio, DWD, COSMO Priority Project COLOBOC , Offenbach Software Requirements Specifications technical requirements:  NetCDF as basic file format for Input/Output  source code in Fortran 2003 / Fortran 95 Standard  technical documentation with doxygen (HTML and/or Latex style documentation generated with the help of “tags” from comments in the Fortran source code)
