About the Weather Station
This website uses data from a personal weather station (PWS) located in the residential neighborhood of Orchard Ridge, in the northwestern corner of the city of Porterville, California. The station is privately owned and operated. It is not affiliated with the City of Porterville and should not be considered an officially recognized station for weather reporting.
A weather station has been in continuous operation at this Porterville location since February 2003. For over 8 years, the Davis Instruments manufactured Vantage Pro model was used to collect real-time meteorological data. It provided very reliable service until various components started failing in late 2010; these were not easy to replace for the obsolete Vantage Pro model. In March 2011, a new weather station was installed at this location, the Davis Vantage Vue.
The Vantage Vue is a compact solar-powered weather station comprised of a thermo-hygro sensor housed inside a passive radiation shield, an anemometer, a wind vane, and a rain gauge. The station wirelessly transmits real-time temperature, humidity, wind, and rain data to an indoor console, about 60 feet away. The indoor console has a wired USB connection to a PC-based desktop computer running Microsoft Windows 7. All raw data is processed and values calculated for barometric pressure, dew point, heat index, wind chill and other parameters, which are then uploaded to this website using Weather Display weather station software. This website is updated with real-time meteorological data approximately every 5 seconds.
Weather Display software is also used to continuously upload data from this station to the Citizen Weather Observer Program (CWOP), PWS Weather (a partnership between HAMweather and Weather For You), and Weather Underground. The data upload frequency to these resources varies from 5 seconds to 10 minutes.
CWOP in particular is instrumental in sharing PWS data with the rest of the world. CWOP servers continuously transmit PWS data to FINDU, a database for archiving weather, geographic location, telemetry, and message data. At 15-minute intervals, NOAA automatically fetches the latest PWS data from FINDU and ingests it into the MADIS database where all data is quality controlled for accuracy and spatial consistency, and then merged with data from over 25,000 Automated Surface Observing System (ASOS) locations. Data from MADIS is then disseminated to other NOAA agencies, including National Weather Service (NWS) offices throughout the United States, which use the data for weather forecasting. Over 500 academic, science, and government organizations around the world use the MADIS data for education and research purposes.
