Lake Huron Weather - lakehuronweather.org is a member of the Citizen Weather Observer Program (CWOP). The above charts represent data reported to CWOP for Cordwood Point - Cheboygan, Michigan (C3699 actuals in blue) with the predicted data based on surrounding stations (C3699 Analysis in red).

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.

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.

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.

Many thanks go to Phillip Gladstone at CWOP for his dedication to providing the needed accuracy and quality checks for the amateur weather observer.
