An FSL and CWOP Collaboration Increases Weather Observations for NOAA

The Citizen Weather Observer Program (CWOP) data stream is now being sent from the Forecast Systems Laboratory (FSL) Meteorological Assimilation Data Ingest System (MADIS) to MesoWest in Salt Lake City, which in turn forwards the data to all Weather Forecast Offices (WFOs) in the Western Region of the National Weather Service (NWS). CWOP is a program of volunteer observers, organized by FSL, who supply and operate their own weather instruments and contribute the real-time weather data to NOAA as a public service. Presently there are over a thousand CWOP data contributors. Their data, along with other mesonet data collected by the FSL MADIS program, are being sent to nearly 70 NWS WFOs across the country, and also to a wide variety of other users, including the National Centers for Environmental Prediction and the National Climatic Data Center. A full list of the MADIS mesonet data providers and real-time displays of the mesonet observations are available from FSL.
