Welcome to the Combe Raleigh Weather Station, based at The Old School.

The Station is based on the Davis Vantage Pro 2 Plus and Wireless Envoy. Wind Instruments are located on the antenna mast in the garden, with the Integrated Sensor Suite (ISS) mounted on a wooden post, at 1.5m above the lawn. These sensors are UV, Solar, Temp Humidity and Rain Bucket. The Davis Wireless Envoy is then routed through a WeatherLink Datalogger and into a Virtual Server, within a VMWare ESXi 6 Hypervisor.

The weather server is running Apache2, PHP5 and mysql5 as well as Weather-Display and WeatherDisplayLive. The station is backed up with a UPS and battery backup for the Data Logger which also has memory for 30 days of weather data in the event of software failure / hardware outage. Weather Data is backed up externally to an optical drive in case of server crash.

The station has been operational since 2006, located in Ottery St Mary until December 2011 and then moved to Combe Raleigh from January 2012.

Supplementary sensors based on 1-wire technology are used for Soil Temps, Grass Temp and Leaf Wetness. These are used with the WD software and data added to the mysql databse for further processing and display. A Blitzortung Lightning System is also installed with a 0.71m dual coil antenna located in the garden.

The weather software running the website is Weather Display and WeatherDisplayLive which are configured to maintain the data and display it efficiently. These products are available from the Weathershop. The website CMS is Joomla, and is used to maintain the content of the site. Phoca add-on's are added to provide extra functionality. Other software used such as the dynamic graphing code using jpgraph has been written by the author, which is available on request.

The Forecast functionality, which uses WXSIM, a local atmospheric modeling application provides accurate weather forecasting for the local area (-/+ 10 Miles). This software processes weather input from multiple sources and uses locally recorded data from the weather station database. The Accuracy of this software is continually being compared with the actual weather and is available from this site.

We have appeared on BBC One's Inside Out Programme in 2008, the Davis.net Newsletter and the Local East Devon Mid-Week Herald.
