The Citizen Weather Observer Program (CWOP) is a private-public partnership with three main goals.
1) to collect weather data contributed by citizens.
2) to make this data available for weather services and homeland security.
3) to provide feedback to the data contributors so that they have the tools to check and improve their data quality.
