OAR-GSD Citizen Weather Observer Program (CWOP)
browse graphic Many citizen weather stations are producing weather data today. When these data are used only by the weather station owners, data quality is not a big issue. With the communications revolution and the vast capabilities of the internet, many people with weather stations are sending their weather data far and wide for other people to use. In that case, data quality matters. The Citizen Weather Observer Program (CWOP) is a private-public partnership with three main goals: 1) to collect weather data contributed by private citizens; 2) to make these data available for public weather services; and 3) to provide feedback to the data contributors so that they have the tools to improve the quality of their data. In fact, the web address, wxqa.com, stands for weather quality assurance. Nearly 2000 citizen weather stations, located world-wide, have sent in data and this graph shows the number of North American CWOP stations that data were received from over the past four days.
