Methods

The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures

Current Methods

  • Meteorological data
    Started: 2004-07-22

    The station provides near real-time monitoring for meteorological variables including wind speed and direction, air temperature, relative humidity, barometric pressure, precipitation and total solar irradiance. Data are automatically downloaded via radio frequency modem.
