Here are some examples of how you can use the gscpy package with GRASS GIS. In the examples most of the modules are executed within the GRASS terminal. It is also possible to do all these steps with the graphical GUI. Most of the examples are from FOSS4G 2014 workshop
These data are from here. These data are already in a GRASS GIS database. To show the import routines I exported the files within the mapset climate_2000_2012 with out.l.gdal. This mapset contains temperature and precipitation series for North Carolina from State Climate Office of North Carolina.
