 CWOP - The Citizen Weather Observing Program


Do you have a well-placed personal weather station at your home or business?  Would you like to share your data with the world?  You can if you send your data to the Citizen Weather Observing Program (CWOP)!

CWOP is a volunteer-based network that allows owners of personal weather stations to share their station’s live data with the National Weather Service, emergency managers, wild land fire fighters, and Universities worldwide.  There are several options to getting your data online – inexpensive (even free) software programs, and extremely reliable, energy-efficient ‘internet devices.’  If you have a well-sited home weather station, and a broadband internet connection, you’re just a few steps away from contributing your data to CWOP.
