Soil Temperature Errors

This is the time of year that the soil temperature data from the North Dakota Agricultural Weather Network, usually referenced as NDAWN, is widely used.   NDAWN has 161 sites, meaning 161 different ways that rodents, the wind and thaw/freeze cycles try to destroy the soil temperature sensors at these stations.  In turn, you may find a station or two where a sensor is 20, 30 or more degrees warmer than nearby sites.   Soil temperatures don’t fluctuate all that much from site to site, so if the station nearest to your location has some “wacky” temperatures, just use the site nearby, as that is likely pretty accurate for your area.  The NDAWN team is out there fixing as fast as they can.
