Ground-based instrumentation

Two ground-based intruments network will be deployed in Brittany:

  • KITcube is an integrated atmospheric observation system designed for observations of the meso-scale thermodynamic and dynamic structure of the lower troposphere. During NAWDIC, a network of five Doppler wind lidars and five water vapor lidars will be established that stretches in a transect from the coast to inland (see figure).
  • Four ground-based Doppler cloud BASTA radars, a wind lidar and a water vapour lidar will be deployed by the French partners. Each instrumented site will include two radars pointing in two nonlinear directions in order to retrieve two components of the winds. The two lidars will be located in Lannion (see figure) because on the Brest site the radars will be closer to KITcube lidars.

  • The deployment of the French radars/lidars on two well-separated coastal sites will complement the deployment of the KITcube radars/lidars which will be more localized and oriented toward land. The synergy between the different platforms will allow us to observe (i) the transition of high-wind features from ocean to land, and (ii) the vertical structure of dry intrusions, cold fronts, and cloud heads as well as their spatio-temporal evolution. The novel character of the instrumentation strategy relies on the deployment of multiple state-of-the-art remote sensing instruments in a limited zone to measure properties of turbulence and convective rolls in the boundary layer during the occurrence of a storm.
