Abstract:
We are installing a network of Micro-pulse lidars (MPLs) with the ability to detect clouds, aerosols and the planetary boundary layer, as well as to differentiate between water and ice in clouds via polarization measurements. We will be installing 4 MPL mini-HD systems in Eureka NU, Halifax NS, London ON, and Sherbrooke QC in the fall, along with a fifth MPL mini already operating at the University of Toronto (D. Wunch, PI). These instruments will form a network capable of detecting and tracking wildfire smoke, volcanic ash and pollutants. Our network will be a part of the existing European E-PROFILE and NASA MPLNET networks, allowing for rapid sharing of data and access to measurements from a large number of automated lidars and ceilometers. Before deployment to the sites we will perform an inter-comparison of the 5 lidars at the Université de Sherbrooke (UdS). UdS is an AERONET site and has an extensive suite of calibrated aerosol instruments. After the calibration period, the MPLs will be deployed to the various sites. I will be presenting the intercomparison of these calibration measurements and the initial results of the network measurements.
