Maintenance of the weather buoy.

  • The buoy can be detached from the mooring, towed to shore, and the top removed to access data loggers and batteries on the inside.
  • Weather data is collected every hour. A computer, using a telephone modem, calls a relay station located in the Crater Lake Lodge. The relay station, using a radio modem, then calls the weather buoy and establishes a two-way connection between the buoy and the computer so data can be collected.
  • The HQ computer then transmits the data to the public website for use by staff, the National Weather Service, and other interested parties.
