SUMMARY:Research Seminar: Dr. Sunilkumar Kudilil
DESCRIPTION:Dr. Sunilkumar Kudilil | Visiting Research Scientist\, Universi
 ty of California\, Riverside \nTime: 2:00 PM — 3:00 PM\nDate: Monday\, J

  ID: 92301867487\; Passcode:  611524)\nTitle: Atmospheric Aerosols: From B
 alloon Observations and Aircraft Emissions to Free- Space Optical Communic
 ation.\nAbstract: In this talk\, I will present an integrated view of how 
 atmospheric aerosols\, particularly absorbing black carbon particles\, inf
 luence optical propagation and free-space optical communication link perfo
 rmance. I will begin by introducing the basic physics of FSO systems\, the
  role of optical turbulence\, and the additional impact of aerosol loading
  on signal attenuation\, scintillation\, and link reliability. I will then
  discuss field experiments based on high-altitude balloon-borne observatio
 ns of black carbon\, where elevated BC layers were observed in the upper t
 roposphere\, particularly near aircraft cruise altitudes. These observatio
 ns will be examined in relation to aircraft emissions\, possible vertical 
 transport pathways\, and the radiative and optical significance of absorbi
 ng aerosol layers. Finally\, I will briefly discuss marine aerosols as a f
 uture research direction\, highlighting their potential influence on laser
  beam propagation in coastal and oceanic communication environments.\nBio:
  Sunilkumar Kudilil is a research scientist specializing in atmospheric sc
 ience and optical beam propagation\, with a focus on how aerosols and atmo
 spheric turbulence affect optical signals and communication systems. His w
 ork bridges communication engineering and atmospheric science\, aiming to 
 improve our understanding of atmospheric processes and their implications 
 for emerging optical technologies. Before joining UCR\, he served as a Pro
 ject Scientist at the Indian Institute of Science (IISc)\, Bangalore\, Ind
 ia\, where he played a key role in designing scientific payloads for high-
 altitude balloon experiments to measure atmospheric aerosols in the upper 
 troposphere and lower stratosphere. In parallel\, he investigated aircraft
  emissions and their impacts on the atmospheric radiative energy balance\,
  contributing to a more refined understanding of anthropogenic influences 
 in the upper atmosphere.
