process to convert RFC temperature and precip grids to DSS

GRIDDED DATA CONVERSION

This product downloads gridded data in netCDF format from the Northwest River Forecast Center and converts to a .DSS file.

Adding Basins

The basins2clip.csv file contains subbasin information this program uses to create gridded data in DSS files. To add basins to this file add a line to the file. The coordinates are in AEA. Utilites in the script/extents directory can be used to get basin extents from the models .mod file.

Grid Units are in Meters.

Example NetCDF Data

Obs Prec for the 24 hour period ending at 12Z on Dec 12, 2016. The nc file contains 5 layers: 24hr and four 6hr files. https://www.nwrfc.noaa.gov/weather/netcdf/precip_ptr_grid_20161216.nc.gz

Obs Temp for the previous 24 period ending at 12Z on Dec 12, 2016. The nc file contains 6 layers: four 6hr files of instantaneous temp at 18,00,06,12Z and max and min temp. https://www.nwrfc.noaa.gov/weather/netcdf/temperature_ptr_grid_20161216.nc.gz

Forecast Prec with layers representing 6hr precip totals extending 10 days into the future. https://www.nwrfc.noaa.gov/weather/netcdf/qpf06f_has_2016121612f240_stegemil_201612161343.nc.gz

Forecast Max Temp with layers representing maximum daily temperature extending 10 days into the future https://www.nwrfc.noaa.gov/weather/netcdf/tx24f_has_2016121612f240_stegemil_201612161342.nc.gz

Forecast Min Temp with layers representing minimum daily temperature extending 10 days into the future https://www.nwrfc.noaa.gov/weather/netcdf/tn24f_has_2016121612f240_stegemil_201612161342.nc.gz

Rebuilding Virtual Environment

Currently this program uses Python 2.7. The dependency requirements are stored in docs/requirements.txt. You can use the following line rebuild the virtual environment.
