Providing Live Weather and Historic Climate Information for Chelmsford

This is a private run weather station in Chelmsford Essex that was started in Dec 2011 after a long intrest in weather and climate data. The weather station originally in use was a Oregon Scientific WRM200 Weather station, and over the years the site has been run has been upgraded as time and money allow

The 2nd Weather Station in use was an Original Davis Vantage Pro station. This was a old 2nd hand Station purchased off eBay, and had data also supplied by a 1-Wire Solar sensor. Whilst this offered good performace, the station was old, and often suffered failures with erroneous readings.

The 3rd weather station in use which is now currently supplying data to CM2Weather is the Davis Wireless Vantage Pro2 Plus with UV & Solar Radiation Sensors , and this now has the benefits of being a Wireless Station like the Original Oregon Scientific Station, and with the addition of both UV and Solar Sensors. A Daytime Fan has also been added, and has helped to improve temperature readings during the summer months when the station sits in direct sunlight.

Data from the Station is uploaded to the Website every 15 minutes. The meteorological day used at this station ends at midnight.
