Notebook for retrieval of precipitation, air temperature, and snow water equivalent measurements at SNOTEL sites

This notebook has been developed to retrieve precipitation, air temperature, and snow water equivalent measured at the Natural Resources Conservation Service (NRCS) SNOTEL sites by calling its Consortium of Universities for the Advancement of Hydrologic Science, Inc (CUAHSI) web service. An input file SNOTEL_indices_at_NWM.csv includes site information and is used in the scripts. In the code directory , there are three Jupyter Notebooks.

- SNOTEL_Download_Retrieve_swe_p_snowdepth.ipynb downloads the precipitation and snow water equivalent over each ecoregion. The main function changes the units from inch to mm. The results are CSV files for each variable for each ecoregion.
- SNOTEL_Download_Retrieve_temp downloads the air temperature and the main function changes the unit from F to C. The results are CSV files for each ecoregion.
- SNOTEL_Pre-Processing.ipynb uses an input file, called SNOTEL_indices_at_NWM.csv within the input directory, as well as the downloaded CSV files to create a single file for each variable that includes site information and variables values.
