    Data is a set of NetCDF files containing runs for a climate simulation. The compilers of the database provide a FORTRAN to extract data that would be suitable for our purpose, but setting up NetCDF on FORTRAN is going to take more time than we are happy with (this is NOT an area of expertise for us). What is needed is to use the data files, either through the FORTRAN subroutine or otherwise, to extract data for a few locations across the times in the model. Desired output is one or more Excel or CSV files with the variables in the model (temperature, pressure, wind data, atmosphere data) for each time. One file per model and location would be suitable. At present there would be 4 locations and 3 or 4 model databases. The databases themselves are online and we have permission to use them (...
