Abstract:
Starting in the early 60’s and following the invention of lasers, the laser remote sensing (LiDAR) technique has been used to probe the terrestrial atmosphere. This powerful technique is based on signal analysis from the interaction of matter with the laser beam, which includes Rayleigh and Mie scattering, Raman scattering, resonance scattering, fluorescence, absorption, Doppler shift and differential absorption and scattering. LiDAR has been applied to a wide range of environmental remote sensing applications.
In this presentation we will quickly review the basic interactions between laser and matter in the atmosphere (aerosols-clouds-gases), the hydrosphere and the biosphere. We will then focus on our LiDAR development efforts and ongoing research on the vertical profiling of tropospheric water vapor, ozone, aerosols, bioaerosols and clouds. We will then discuss applications of these lidar retrievals to characterize sea pollution, aerosol typing and air quality monitoring, bioaerosol monitoring, even tree health assessment. We discuss how our data is used to improve atmospheric models and forecasts and conclude with future directions and perspectives.
Short biography:
Prof. Alex. Papayannis (Dipl. Ing., DEA, Ph.D.) is the Director of the Laboratory of Optoelectronics, Lasers and Applications and Research Professor of Atmospheric Physics, Laser Technology and Laser Remote Sensing, at the National Technical University of Athens. He is a LiDAR expert in vertical profiling of atmospheric parameters, aerosols, clouds and gases (O3, H2O, Glyoxal) in the troposphere, in combination with sun photometry, satellite data, in situ aerosol measurements and meteorological modelling. He has participated in 68 research projects (EU, NASA, ESA, GAW-WMO, INPE-Brazil, CNRS-France and Greek National funds). He is founder of the RAYMETRICS SA lidar company (www.raymetrics.com), which is the first lidar company in the world with customers in throughout Europe, Americas, Asia and Africa. He is founding member of the European lidar Network (EARLINET), as well as member (2008-2015) and current President (2015-2023) of the International Coordination Group for Laser Atmospheric Studies (ICLAS). He has served as Member of the Scientific Committee and Co-chair of more than 25 International Conferences, related to lidar atmospheric/meteorological applications. He has published 132 papers in peer-reviewed journals, 6 Book chapters and 250 papers in peer-reviewed International Conferences Proceedings. He has received more than 8.120 citations (h-index 46) in Google Scholar. He has supervised more 15 Ph.D. students and 60 M.Sc. Diploma Theses at NTUA.
