more information

Punxsutawney West End Weather is a proud member of the Citizen Weather Observer Program (CWOP).
The above charts represent data reported to CWOP for Punxsutawney West End Weather (D3331 actuals in blue) with the predicted data, based on surrounding stations (D3331 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 OK will appear. Otherwise, a red x-mark not OK 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.

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