source: palm/trunk/SOURCE/time_integration.f90 @ 4226

Last change on this file since 4226 was 4226, checked in by suehring, 5 years ago
Offline nesting: data input modularized; time variable is defined relative to time_utc_init, so that input data is correctly mapped to actual model time; checks rephrased and new checks for the time dimension added; Netcdf input: routine to retrieve dimension length renamed
