The network consists of nine fixed locations evenly distributed across Britain, and one mobile facility normally located at Watnall near Nottingham (Adam et al. 2017). The first lidar was installed at the Camborne site in 2015, and the network was fully installed by September 2016. The lidars, Raymetrics LR111-300s, are bespoke systems developed and manufactured by Raymetrics to meet the Met Office and London Volcanic Ash Advisory Centre (VAAC) needs. The instruments emit at 355nm and have polar and co-polar depolarisation detection channels at 355nm, and an N2 Raman detection channel at 387nm. The polarization channels of each lidar are calibrated using the + / - 45 degree procedure from Freudenthaler et al. 2009. Alignment is ensured using the telecover test described in Freudenthaler et al. 2018. Co-located with the lidars are Cimel CE318 multiband sun-photometers, which are part of the AERONET network. Each lidar is operated remotely from the Met Office Exeter headquarters. The primary aim of the network is the detection and quantification of volcanic ash aerosols during a volcanic event, and the network is only test fired only for a few hours each week. Outside of these times the lidars may be fired if there is a mineral dust outbreak or other such aerosol event of interest.

The fourth element, the reference or compensation element, is exposed to the airflow but not to cloud water. This element is used to establish the dry air power term which is subtracted from the power through the LWC and TWC elements and so giving just the power required to maintain the set temperature in the presence of cloud.
