~40 stations, currently multisensor device plus pyranometer and tipping rain bucket (transitioning in 2022-2024 to individual weather sensors for all elements), collecting the following data for NOAA/HADS: Temperature, Relative Humidity, Barometric Pressure, Wind Direction, Wind Speed, Solar Radiation, Rainfall.

Minnesota’s climate “mesonet,” overseen by the DNR State Climatology Office, was begun in 2015, with the original intention of providing potential evapotranspiration information to agricultural producers, and specifically to application developers who were creating irrigation scheduling tools. These stations also improve Minnesota’s coverage of climate monitoring capabilities. Currently, the state has 40 stations, concentrated first in agricultural areas, and then in areas with data gaps. Most of the sites are on state lands, for instance in State Parks or Scientific and Natural Areas, but two are also on tribal lands. About half of the stations only collect climate data, and the other half have been added onto existing stream gauging sites. In 2022-2024, these sites will be upgraded to include better-performing wind, temperature, humidity, and pressure sensors.
