Andy's Live Local Weather Station - Thompson Farms is a proud member of the Citizen Weather Observer Program (CWOP). The above charts represent data reported to CWOP for Hanska, MN (D7572 actuals in blue) with the predicted data based on surrounding stations (D7572 Analysis in red).

Data Quality:
The MADIS value represents the percentage of observations that have successfully passed the MADIS QC checks. If the Madis rating is within the acceptable limits, a green check will appear. Otherwise, a red x-mark will appear indicating that the data has not passed quality control.

Errors
If the above errors are POSITIVE, this means that the analysis variable is HIGHER than the reported variable. This means that the sensor is reading a variable lower than expected. If the above errors are NEGATIVE, this means that the analysis variable is LOWER than the reported variable. This means that the sensor is reading a variable higher than expected.

CWOP:
The Citizen Weather Observer Program (CWOP) is a private-public partnership with the National Oceanic & Atmospheric Administration. Its three main goals: 1) to collect weather data contributed by citizens; 2) to make these data available for weather services; and 3) to provide feedback to the data contributors so that they have the tools to check and improve their data quality. There are over 8,000 registered CWOP members world wide and a graph of the number of North American CWOP stations sending data over the past four days is shown under the older name APRSWXNET. The number of world-wide citizen weather stations sending data to CWOP is shown over a multi-year period. CWOP members send their weather data by internet alone or internet-wireless combination to the findU server and then every five minutes, the data are sent from the findU server to the NOAA MADIS server. The data undergo quality checking and then are distributed to users. There are over 500 different user organizations of the CWOP mesonet data. Here is a partial list: NWS Weather Forecast Offices, National Center for Environmental Prediction, National Ocean Service, National Transportation Safety Board, National Center for Atmospheric Research, Department of Homeland Security, Denver Urban Drainage and Flood Control District, Colorado Avalanche Information Center, Kennedy Space Center, NASA Marshall Space Flight Center, University Corporation for Atmospheric Research, Embry-Riddle Aeronautical University, MIT Lincoln Laboratories, University of Utah, Penn State University, Mississippi State University, University of Alaska, University of North Dakota, Hampton University, Texas A & M University, University of Hawaii, Florida State University, and Weather Underground.
