All risk for the use of this information is assumed by the readers of this page.

In particular, the output shown for the air quality index (AQI) and the text forecasts are entirely the experimental work of an amateur hobbyist. As such, they could very well contain or convey completely incorrect information (for example, the AQI reading is based on the last measurement of pollutants only, and is not an average over multiple hours!)

About this weather station:
Location
Latitude:
37° 15.75' N
Longitude:
122° 00.20' W
Altitude:
376 feet
This station uses a Vantage Pro2, controlled by
'weewx', an experimental
weather software system written in Python. Weewx
was designed to be simple, fast, and easy to understand by
leveraging modern software concepts.
This system is powered by the open source Weewx package.
This system uses the open source Purple Air extensions to Weewx package by Kenneth Baker to obtain the raw PM2.5 values.
Thanks to JaneAndJohn.org for PHP-based RSS weather-feed code used in a prior iteration of this site.
Thanks to Ken True at Saratoga-Weather.org for pointers to good warning scripts, used in a prior iteration, and for being a great overall resource for scripting weather websites. Also, the idea to ignore certificate errors from the NOAA/NWS website comes from these scripts.
Thanks to Tom at carterlake.org for a script that caused me to want to learn how to obtain the raw data of a National Weather Service forecast, that triggered my building my own set of scripts. He has also created another great overall resource for scripting weather websites.
The raw data on which the forecasts are built, and the icons, come from the National Weather Service.
This system utilizes the xmlize utility written by Hans Anderson.
This system utilizes the NuSOAP package for reading SOAP data feeds, licensed under GPL v2.1 and later, by NuSphere Corporation and Dietrich Ayala.
The URL used to get the alerts, and the idea to use cURL to get them, comes from the "NWS Alerts" PHP package by Rick "Curly" at the WXForum web site.
Ideas for grabbing some of the information via XML liberally lifted from PXWeather by Jonathan M. Abbett.
