Comments Other meteorological data are obtained from the University weather station (1 km west of IDMP station): - Incoming long-wave radiation: Eppley PIR - Short-wave radiation (incoming and outgoing): Middleton EP07 - Dry Bulb Temperature and Relative Humidity: Vaisala HMP 35DF - Wind speed and direction: RM Young 05103 The Hagner sensors were calibrated by Hagner in Sweden in June, 1993. The Eppley NIP has been calibrated by the National Solar Radiation Laboratory of Environment Canada at 6 month intervals. The Eppley radiometers were also calibrated by the National Solar Radiation Laboratory.
