Below are some of the sources of publication that we provide.

CWOP - Citizens Weather Observation Program

The Citizen Weather Observer Program (CWOP) is a private-public partnership with three main goals:

  • To collect weather data contributed by citizens
  • To make these data available for weather services
  • To provide feedback to the data contributors so that they have the tools to check and improve their data quality.

There are over 6,000 registered CWOP members world wide.

WeatherUnderground

Weather Underground is one of the largest online weather providers, publishing over 132 million page requests and 7 million unique visitors a month. Founded in 1995 as the Web's first online weather service, Weather Underground has grown into the most comprehensive, user friendly weather web site.

All U.S. forecasts and advisories on the wunderground.com web site are generated by the National Weather Service (NWS). Most U.S. current condition data comes from the Automated Surface Observation System (ASOS) stations located at about 1600 airports throughout the country. The Federal Aviation Administration maintains these sites and provides location and contact information.

The Weather Underground has teamed up with a number of Weather software vendors to build a network of personal weather stations across the globe. These stations provide real-time weather conditions, with updates as frequent as every 8 seconds.
