Methods
The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures
Current Methods
Data from Mount Mansfield station
Started: 1997-01-01This Mount Mansfield station provides basic meteorological variables including wind speed and direction, air temperature, relative humidity, total solar irradiance, photosynthetically active radiation (PAR), and precipitation during non-freezing months. The station is located within a mixed aspen-birch spruce-fir forest, and represents mid-elevation forest meteorology.
Started: 1997-01-01Data are automatically downloaded via radio frequency (RF) modem on a daily basis, with 15 minute average records collected and stored during each downloading cycle. Hourly and daily data formats are made available.

Start Date End Date Note Date Entered 2016-07-19 13:30:00 2016-07-19 15:00:00 Replaced MMW quantum, pyranometer and battery; checked wind anemometer and precipitation gauge. Precipitation gauge was clogged with plant debris, cleaned it out. Have not nullified data yet. 2016-07-20 00:00:00 2016-02-17 23:30:00 2016-04-21 11:15:00 At MMW, some critter bit through the cable that connects the air temperature and relative humidity sensor to the data logger. The sensor and cable were replaced and are functional now. 2016-05-31 14:45:00
