Getting data from Global Forecast System - NOAA

This script is used to access data directly from the GFS system using the information stored in the GrADS Data Server.

The Global Forecast System (GFS) is a National Centers for Environmental Prediction (NCEP) weather forecast model that generates data for dozens of atmospheric and land-soil variables, including temperatures, winds, precipitation, soil moisture, and atmospheric ozone concentration. The system couples four separate models (atmosphere, ocean model, land/soil model, and sea ice) that work together to accurately depict weather conditions.

Working with the script

Libraries needed:

• xarray
• geopandas
• numpy
• datetime
• pathlib
• logging
• click
• warnings

Runnin the Script

This script runs in a python terminal and the following command needs to be used:

• The boundary of the AOI needs to be saved as a shapefile under the boundary_data folder.

python CFS_climateForecastSystemData.py --clim_var=<precipitation or temparature> --bndr=<boundary file name>

For help with the script you can run

python CFS_climateForecastSystemData.py --help

• The final output of the script will be stored in the forecast_data
