Methods

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

Current Methods


  • Started: 1996-07-29

    The station provides near real-time monitoring for meteorological variables including wind speed and direction, air and water temperature, relative humidity, barometric pressure, and total solar irradiance. Data are automatically downloaded via radio frequency modem on an hourly basis with 15 minute average records collected and stored during each downloading cycle. Data are available in an hourly and daily format.
