Weather radar network renewal project timescales

The project is expected to be completed by winter 2016 and the rollout has been split into four phases.

Phase 1 Software Installation

Cyclops-D3 was rolled-out to the whole network during winter 2010-2011.

Phase 2 Resilience/Doppler upgrade

This installed a new Transmitter with Doppler capability at each radar. The full network was upgraded between December 2011 and December 2012.

Phase 3 Infrastructure upgrade 

This phase addresses the Health & Safety requirement to fit stairs to the top of the tower at all sites and will carry out structural repairs where needed. Each site will be non-operational for between six to eight weeks to address these requirements. The first tower upgrade has been completed at Wardon Hill (the semi-operational site), Chenies, Castor Bay and Predannack. Further sites will be upgraded with each Phase Four roll out over the next two to three years. Phases three and four have been combined to reduce the total down time of each radar as much as possible.

Phase 4 Dual Polarisation/Resilience upgrade 

This involves the installation of a new dual channel receiver, dual polarisation antenna and high specification radome. The required outage time for this work is three to four weeks. Once installed the full radar system will be performance tested for eight weeks prior to it being returned to operational status. So far Wardon Hill, Thurnham, Chenies, Castor Bay, Predannack and Cobbacombe upgrades have been completed. The rest of the sites will follow over the next three to four years. The current proposed schedule is:
