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.
