BRIEF DESCRIPTION OF DATA FILE: Multiple year daily averages of meteorological station data for use in LTER Climate Database. Data include daily averages of air temperature with maximum and minimum air temperature and daily precipitation totals.
KEYWORDS: climate, meteorology, temperature, precipitation, rain, air
SITE TYPE: Monitoring
RESEARCH LOCATION:
MON-PR-Governor
Dummer Meteorological Station
Longitude
70.9024065
Latitude 42.75148419
EXPERIMENTAL DESIGN AND 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.
NOTES AND COMMENTS:
VARIABLE DESCRIPTION:
LTER_Site = the three-letter LTER site code
Station = local site name for the weather station (10 character max)
Date = yyyymmdd
Daily_AirTemp_Mean_C = daily mean air temperature (celsius)
Flag_Daily_AirTemp_Mean_C = daily quality flag – E for estimated value
Daily_AirTemp_AbsMax_C = absolute maximum air temperature (celsius)
Flag_Daily_AirTemp_AbsMax_C = daily quality flag – E for estimated value
Daily_AirTemp_AbsMin_C = absolute minimum air temperature (celsius)
Flag_Daily_AirTemp_AbsMin_C = daily quality flag – E for estimated value
Daily_Precip_Total_mm
= daily total precipitation
Flag_Daily_Precip_Total_mm
= daily quality flag – E for estimated value
