The weather station consists of a Davis Instruments Weather Monitor II connected to a 233MHz Pentium PC running Weather Display software. The temperature/humidity sensor is mounted in a Davis Passive Radiation Shield about 8 feet above ground and the anemometer is mounted 27 feet above ground. Every five minutes the weather data is transmitted via Amateur Radio APRS for use by local Amateur Radio operators and Skywarn during severe weather. The data is also sent to the FINDU APRS server in Miami, FL. where it is combined with the data from other Citizen Weather Observer Program (CWOP) stations and is forwarded to the NOAA Forecast Systems Laboratory (FSL) in Bolder, CO. and the National Center for Atmospheric Research. NOAA uses the data in their numerical weather prediction models. FSL submits the data to its Quality Control and Monitoring System providing feedback to the station operator on the performance of the station sensors compared to other local sources of weather data. The weather data is also submitted to the Weather Underground and Weather for You / Hamweather.
Skywarn is a National Weather Service (NWS) program of trained volunteer severe weather spotters. Skywarn spotters are the "eyes and ears" of the National Weather Service providing reports of severe weather conditions and weather related damage. Much of the spotter network is provided by Amateur Radio operators but the NWS also maintains a toll free telephone line for those spotters that are not ham radio operators. I am a trained Skywarn spotter and work with the Triad Skywarn group.
