|Abstract:||Year 2007 meteorological measurements at Governor's Academy and MBL Marshview Farm of air temperature, humidity, precipitation, solar radiation, photosynthetically active radiation (PAR), wind speed and direction and barometric pressure. Sensors conduct measurements every 5 secs and measurements are reported as averages or totals for 15 minute intervals.|
15 minute averages are reported for air temperature, humidity, solar radiation, PAR, wind speed and direction and barometric pressure.
15 minute totals are reported for precipitation.

|Methods:||The data file is a summary of daily weather data from the PIE LTER weather station located at Governor's Academy in Byefield, MA. and MBL Marshview Farm in Newbury, MA.|
On July 30, 2007, Julian Day 211, the weather station was moved from Governor's Academy to the Marshview Farm field station off Rt 1, Newbury, MA 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.
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.,
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.
