This is a demonstration of how to plot water level data from the Henry Mount Soil Climate database with precipitation data from nearest NOAA weather station.
It shows use of two new experimental soilDB-type functions for the NOAA API
get_NOAA_stations_nearXY()- find all stations near a specified lat/lng and bounding box (limit 1000)
get_NOAA_GHCND_by_stationyear()- get GHCND data (daily summaries) by station ID and year (limit 1000)
Note that using the NOAA API requires an API token specified as argument to above two functions. A token can be obtained for free at the following link: https://www.ncdc.noaa.gov/cdo-web/token
