Daily meteorological data (2000-2018) from PIE LTER weather stations located in Byfield/Newbury, MA

Abstract: 

Meteorological data daily averages and daily fluxes for stations located at Governor's Academy and MBL Marshview Farm, Newbury, MA. Data includes air temeprature, precipitation, relative humidity, solar radiation, PAR, wind and air pressure measurements. Years 2000 to 2007 the station was located at Governor's Academy, Newbury, MA and was moved July 30, 2007 to the MBL Marshview Farm field station property where it is currently located.

Methods: 

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.

During maintenance on Nov 7, 2017, the precipitation collector funnel had water in it, clogged, ~ 5 cm of water. Measured precipitation 15 minute data for preceding months of September and October, suspect due to clogging and has been deleted. Daily precip recorded in this dataset represent daily averages of  four NOAA weather stations in Northeast Massachusetts (Beverly, Haverhill, Lawrence and Newburyport) during the months of September and October 2017. The 15 minute weather data for 2017, MON-PR-Met15min2017, will have the 15 minute precip data removed and notes placed in corresponding comments field.
