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. On July 30, 2007, Julian Day 211, the weather station was moved from Governor Dummer Academy to the Marshview Farm field station off Rt 1, Newbury, approximately 1/2 mile away. The PAR sensor was also changed on July 30, 2007 and was found to be cracked which compromised measurements of PAR prior to July 30. PAR data from Jan 1 to July 30, 2007 at 1645 EST time has been estimated from a Pyranometer to PAR relationship where PAR (uM/m2-sec) = (pyranometer value (kW/m2) X 1982.2) + 1.0783, r2 =0.983.
