Data Table

  • Title: Quality-Controlled Colchester Reef Meteorological Data
  • Start Date: 1996-07-29
  • Description: Measurements of air temperature, barometric pressure, windspeed, precipitation and humidity at the Colchester Reef Station. Readings are taken at sensor arrays at 32 meters and 38 meters above mean sea level. Basic quality control measures have been applied to the data.

  • Purpose: To continuously monitor meteorological variables representative of Lake Champlain for use by researchers, recreationalists, commercial boaters, Champlain Water District and the National Weather Service.

Methods

  • Current Methods
    • Unnamed Method
      • Started: 1996-07-29
      • Method Description: 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.
