SURFACE-WATER RECORDS
GAGE -

Continuous air temperature, relative humidity, wind speed, wind gust speed, wind direction, solar radiation, and battery voltage are measured with a HOBO U30-NRC weather station. These data are recorded quarter-hourly from 25 August 2016 at 09:45 CDT to 30 October 2018 at 10:30 CDT by the HOBO U30-NRC weather station, which has a data logger built into it. The data logger is housed inside the weather-proof PVC shelter. The weather station gage is powered by a 3 watt solar panel and rechargeable station battery that is inside of the weather-proof PVC shelter. Data is downloaded manually and no telemetry or phone line is wired into the weather station gage.

An unheated Onset RG3 tipping-bucket rain gage was deployed at the site on 13 September 2016 at 12:45 CDT to 30 October 2018 at 10:30 CDT. The rain gage is mounted on a green T-post, located approximately 20 ft. west of the HOBO U30-NRC weather station, on the western edge of the west/east tree line. The rain gage has a built-in datalogger, which measures and records precipitation quarter-hourly. Rain gage is nominally accurate to 0.01 inches.

The rain gage was removed from the site on 30 Oct. 2018 at 10:30 CDT. The weather station was discontinued at the site on 30 Oct. 2018 at 10:45 CDT. Data collection for the Impacts on Drainage Recharge study have concluded and all data logging equipment have been removed from the site.

COOPERATION -

This site was operated (2016-2018) by the U.S. Geological Survey as a monitoring piezometer for the Southeast Minnesota Subsurface Drainage Impacts on Groundwater Recharge study. The piezometer began to be used as part of the Southeast Minnesota Subsurface Drainage Impacts on Groundwater Recharge study during 25 Aug. 2016 to 30 Oct. 2018. The GW Drainage Recharge study is a collaborative effort between the Environment and Natural Resources Trust Fund (via Legislative-Citizen Commission on Minnesota Resources (LCCMR)) and the U.S. Geological Survey.

INSTRUMENTATION -

A HOBO U30-NRC weather station was installed at the site on 25 August 2016 at 09:45 CDT. The weather station is mounted on an aluminum tripod, which has several horizontal and vertical arms that are used to mount several meteorological instruments. The weather station is located approximately 20 ft. east of the Onset RG3 rain gage. The weather station has a built-in data logger, which measures and records relative humidity, solar radiation, air temperature, wind gust speed, wind direction, wind speed, and battery voltage quarter-hourly.

A 2-bit temperature/relative humidity smart sensor S-THB-M002 was installed at the site on 25 August 2016 at 09:45 CDT. A solar radiation shield RS3-B is mounted around the temperature/relative humidity smart sensor. The temperature/relative humidity smart sensor is mounted on the HOBO U30-NRC weather station's aluminum tripod mast. The temperature/relative humidity smart sensor is wired into the HOBO U30-NRC datalogger, which measures and records quarter-hourly. 

A solar radiation (silicon pyranometer) smart sensor S-LIB-M003 was installed at the site on 25 August 2016 at 09:45 CDT. The solar radiation smart sensor is mounted on the HOBO U30-NRC weather station's aluminum tripod mast. The solar radiation smart sensor is wired into the HOBO U30-NRC datalogger, which measures and records quarter-hourly. 

A wind speed smart sensor S-WSB-M003 was installed at the site on 25 August 2016 at 09:45 CDT. The wind speed smart sensor is mounted on the HOBO U30-NRC weather station's aluminum tripod mast. The wind speed smart sensor is wired into the HOBO U30-NRC datalogger, which measures and records quarter-hourly. 

A wind direction smart sensor S-WDA-M003 was installed at the site on 25 August 2016 at 09:45 CDT. The wind direction smart sensor is mounted on the HOBO U30-NRC weather station's aluminum tripod mast. The wind direction smart sensor is wired into the HOBO U30-NRC datalogger, which measures and records quarter-hourly. 

An unheated Onset RG3 tipping-bucket rain gage was installed at the site on 13 September 2016 at 12:45 CDT. The rain gage is mounted on a green T-post, located approximately 20 ft. west of the HOBO weather station. The rain gage has a built-in data logger, which measures and records precipitation quarter-hourly. Rain gage is nominally accurate to 0.01 inches.

The rain gage was removed from the site on 30 Oct. 2018 at 10:30 CDT. The weather station was discontinued at the site on 30 Oct. 2018 at 10:45 CDT. Data collection for the Impacts on Drainage Recharge study have concluded and all data logging equipment have been removed from the site.

REMARKS - Relative humidity, solar radiation, air temperature, wind speed, wind gust speed, and wind direction data sets were all checked against a nearby weather station at "South Site Weather Station" (USGS 433241092254601), which was located 3.3 miles SSE of this weather station. Data sets were checked for anomalies such a spikes or non-changing data values. Any anomalies were removed from the data sets during the work/review data processing procedures.
