All precipitation data is raw and has not been reviewed. Data may not represent true measurements at the time of collection. Precipitation bars on the precipitation chart are marked in red when the temperatures recorded at the times when tips occurred, averaged over the day, is less than 36° F, likely indicating the possibility of frozen precipitation. The NDDWR uses a Texas Instruments TR-525I tipping bucket rain gauge with no heater. Potential influencers include, but are not limited to, cold weather, debris in the collector, excessive wind, rain gauge calibration drift or equipment malfunction. The tipping bucket rain gauge cannot measure snowfall. Whenever temperatures near freezing, the tipping bucket may not report the correct rainfall. If there is snow on the rain gauge, it may melt on a different day then the precipitation fell. The use of rainfall data between October and April should be carefully examined along with external factors to determine if the data should be used or discarded. More information about the Texas Instruments TR-525I rain gauge can be found here.

All soil data is raw and has not been reviewed. Data may not represent true field conditions at the time of collection. Potential influencers on Meter Teros 12 sensor accuracy include, but are not limited to, sensor malfunction, large bulk electrical conductivity and frozen soil water.
