Fog and precipitation microphysics

Ismail Gultepe

In this presentation, fog and precipitation microphysics will be evaluated using various observations collected at the meteorological supersites, during C-FOG (Coastal-FOG) project, as well as in UOIT (University of Ontario Institute of Technology) climatic wind tunnel (CWT). Observations collected by the in-situ sensors and remote sensing platforms (RSP), in addition to conventional met parameters, were related to precipitation (RN&SN), fog spectra, visibility, 3D wind, and radiative fluxes. RSPs were a ceilometer, LiDar, MWR (profiling microwave radiometer), and MRR (micro rain radar), and GOES-R. For a newly developed UAV (unmanned aerial vehicle) platform applicable to boundary layer research, measurement examples will also be provided. Overall, issues and challenges for prediction of  fog/visibility and precipitation measurements related to aviation, marine, and transportation will be summarized and future work for cold climates will be emphasized.
