Pepperridgenorthvalley.com is a proud member of the Citizen Weather Observer Program (CWOP). The above charts represent data reported to CWOP for North Phoenix, AZ (C3794 actuals in blue) with the predicted data based on surrounding stations (C3794 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.

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

 Pepper Ridge North Valley Random Weather Facts

HUMIDEX
Definition Humidex - Over the years, several measures have been proposed to relate various combinations of temperature and humidity into a single number to approximate what hot, humid weather feels like to the average person. Of these, humidex is the one most familiar to Canadians. Humidex was introduced into Canada in 1965. The index is a summer analogue of the wind chill factor in that it is an equivalent air temperature. Air of a given temperature and humidity is equated in comfort to air of a higher temperature that has a negligible moisture content. Comfort is quite subjective and largely dependent on the age and health of the individual. Weather conditions causing prickly heat in an infant may result in heat cramps in a teenager, heat exhaustion in a middle-aged and heat stroke in a senior. Humidex is also limited as an overall hot-weather comfort index because it does not consider other factors such as pressure, wind speed, precipitation, sunshine or pollen.
