During February several laser rainfall sensors were deployed across the UK to form DiVeN (Disdrometer Verification Network) on a 2000 mile long field campaign. These instruments measure the size and fall speed of each individual particle, which allows the type of precipitation to be empirically deduced.

The goal is to compare this data against the new Met Office dual-polarisation radar network, which has the ability to determine precipitation type (rain, snow, hail etc). There are currently 10 instruments deployed with 3 more planned; they will be operating in the field for up to 3 years. 

On the map to the right, laser rainfall sensors are marked in blue, and Met Office dual-polarisation radars in grey.

In a few months an open-access website for animated live viewing and downloading of the data will be available to all, hosted on NCAS servers. This live view will be shared with forecasters at the Met Office as a trial to determine whether the information is helpful operationally.
