Details

station_number is a combination of the USAF station ID and the NCDC WBAN number in the form '(USAF ID)-(WBAN ID)'. If a WBAN ID does not exist, a value of '99999' should be used in its place.

Example with WBAN ID - '911650-22536'
Example without WBAN ID - '010015-99999' Station numbers can be found in the dataframe returned by get_stations_info() or through the NOAA's graphical tool at https://gis.ncdc.noaa.gov/maps/ncei/cdo/hourly
