Methods
The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures
Current Methods
Meteorology data
Started: 1999-07-26This 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. Data are stored as 15 minute averages to a data storage module changed every 57 days or less. The station is located within a mixed aspen-birch spruce-fir forest, and represents mid-elevation forest meteorology.
