| Methods: | The data file is a summary of daily weather data from the PIE LTER weather station located at Governor Dummer Academy in Byefield, MA. The weather station is solar powered using a Solarex MSX-20 20 watt solar module including a 12V charger and regulator and 12 AH lead acid battery. The system was supplied by Campbell Scientific Inc., contact Doug Bryson, 435-750-9549. The data logger is supplied by Campbell Scientific CR10X-1M data logger with 1 megabyte memory storage module and PC208W Windows data logging software. The enclosure and tower is a Campbell Scientific ENC 12/14 (12” X 14” weather proof enclosure), CM10 (10’ tripod, grounding kit and CM10 guy wire kit. Sensors used: Temperature and Humidity Vaisala HMP45C temperature and humidity sensor with solar radiation shield. Specifications: +/- 1% accuracy over – 40 to 60 °C temperature range Precipitation gauge Texas Electronic TE525WS-L, 8” rain gage with CS705 precipitation adapter for snow fall. Specifications: +/- 1% accuracy up to 1 in./hr. Pyranometer Solar radiation, 400-1100 nm, Licor LI200X-L pyranometer Specifications: +/- 3% typical accuracy PAR Photosynthetically active radiation, 400-700 nm, Licor LI190SB quantum sensor Specifications: +/- 5% calibration, National Institute of Standards Technology Temperature and Humidity Vaisala HMP45C temperature and humidity sensor with solar radiation shield. Specifications: +/- 1% accuracy over – 40 to 60 °C temperature range Wind speed and direction RM Young 05103 Wind monitor Barometric pressure Vaisala PTB101B Specifications: +/- 4 mB @ -20oC to +45o C. |
