McMaster Weather Station (MUWS)

McMaster Weather Station is operated by the Hydrometeorology and Climatology Lab in the School of Geography and Earth Sciences, McMaster University, Hamilton, Ontario, Canada. It is being supervised by Dr. Altaf Arain, associate professor in the School. The primary purpose of this weather station is to support undergraduate and graduate teaching and serve campus and surrounding community in west Hamilton. The station was established in October 2007 and a number of meteorological variables are being measured. Those using data are encouraged to check sensor details.
