Meteorological measurements in 2021, close to Lake Elmo

Continuous observations were made of weather conditions at the pond, including temperature, wind velocity, wind direction, solar radiation, humidity, and rainfall. The observations were made from February 3rd, 2021 to March 21th 2021, The pond used for these observations is situated in Lake Elmo, Minnesota, USA, the pond center located at 45.0220, -92.8916. An Ambient Weather Model WS-2902C observing station was situated on the North-East side of the pond, about 2 m from the nominal shoreline. The data was collected to experimentally determine effects of surface albedo modification on ice melt and thermodynamic processes of a freshwater pond. In this experiment we applied a coating of reflective hollow glass microspheres to a test section, while leaving a control section unmodified. The data was used to develop a thermodynamic model of the pond using weather conditions to model heat flows and to confirm snowfall events. The Ambient Weather observing station transmits its readings via WiFi to a WS-2902C receiver which is connected wirelessly to the Internet, and the readings are stored for one year. These data points were downloaded and processed
