PIE LTER year 2020, meteorological data, 15 minute intervals, from the PIE LTER Marshview Farm weather station located in Newbury, MA

Abstract: 

Year 2020 meteorological measurements at 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 MBL Marshview Farm in Newbury, 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.,
The data logger is supplied by Campbell Scientific CR10X-1M data logger with 1 megabyte memory storage module and Campbell Scientific Loggernet 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.
