Abstract Information :

AbstractrnAssessing and forecasting how atmospheric aerosols impact the environment is an ongoing challenge due to the diverse sources of primary and secondary particles and the complex pathways by which these particles are transformed and transported. As chemical transport models become more sophisticated, higher resolution and more accurate measurements of aerosol properties are needed for model validation, parameterizations of aerosol properties, and better model initializations and data assimilations.rnrnDroplet Measurement Technologies (Droplet) has developed a suite of in situ sensors for measuring the microphysical, optical, and chemical properties of aerosol and cloud properties. Droplet is also a commercial provider of the Micro Pulse lidar (MPL) and the Mini Micro Pulse Lidar (MiniMPL). In collaboration with scientists from the University of Manchester Droplet is developing a measurement system that couples surface measurements of aerosol particles, refractory black carbon (rBC), equivalent black carbon (eBC), fluorescing aerosol particles (FAP) and cloud condensation nuclei (CCN), with vertical profiles of polarized backscatter as input to a chemical transport model that will incorporate these data along other meteorological parameters to do near realtime forecasting of concentrations of black carbon, hygroscopic and bioaerosol-like particles for the local area and regions immediately downwind from the sensors.rnrnIn this presentation we will provide a brief overview of the measurements systems and their capabilities, describe how the in situ and lidar measurements will be coupled, and discuss the conceptual idea for developing the nowcasting system for operational implementation.rn
