This Willie McCool Regional Park Weather site is maintained privately by a neighbor for free and for use by everyone. Sensors include a Davis Vantage Pro II with fan aspirated temperature and humidity. The sensor suite includes a UV index and Solar Radiation measurement. Also included in the sensor suite is a PA-II PurpleAir Air Quality sensor. The data refreshes every few minutes.
The anemometer may not show accurate winds as the house interferes, and depending on wind direction, can be inaccurate. Winds from a northerly direction remain close to accurate, but Easterly, Westerly, and Southern winds have been reported as poor observations.
Sensor data is also uploaded to Weather Underground station ID KNVNORTH11 and the Citizen Weather Observer Program (CWOP) station ID EW0607. Air Quality data is uploaded to PurpleAir's website.
A higher fidelity free data set can be observed here at the WeatherLink website.
