These station are generally 10-15 years old with about half being Vaisala ROSA outstations and half being Findlay Irvine (Mk6 or Mk8). 3 sites are more recent and of the latest technology. They each carry a range of sensors. These weather stations communicate with the Vaisala Bureau at Birmingham via GSM, GPRS or a broadband connection. Vaisala currently have a contract to provide a managed data service which includes the collection, archive, quality analysis and presentation of the data. The sites are currently maintained through our Traffic Signal maintenance contractor. It is the intention of this contract to undertake a replacement programme for these sites over the coming five or 6 years, depending on available funding. Devon County Council is seeking proposals to undertake a replacement programme of its Road Weather Station sites over the next 5 to 6 years. Funding has been secured for the first year of the programme when it is expected that at least seven sites will be replaced to be completed before the end of March 2018. Funding for future years is expected but is not guaranteed and contract extensions may be awarded dependant on continued funds being available.
