About
John A. Reagan is a prominent atmospheric scientist whose research has fundamentally advanced our understanding of atmospheric aerosols and their climatic significance. His work spans aerosol optical characterization, lidar remote sensing, and the integration of ground-based, airborne, and satellite observation systems to quantify aerosol properties with unprecedented precision. Reagan's most influential contribution — garnering 347 citations — derives from his landmark 2005 study computing lidar extinction-to-backscatter ratios for key aerosol types across 26 global AERONET sites, providing the atmospheric science community with essential reference data for interpreting lidar measurements worldwide. This foundational work established benchmark values still widely used in satellite retrieval algorithms and climate modeling. His subsequent research demonstrated the power of combining multiple observational platforms, as illustrated by his 2010 CALIPSO intercomparison study, which reconciled aerosol retrievals from AERONET, airborne high spectral resolution lidar, and satellite measurements during a major field campaign near Washington, D.C. Reagan's regional studies over Bozeman, Montana, further showcase his expertise in characterizing continental and biomass-burning aerosols using coordinated multi-instrument deployments, including lidar, solar radiometers, and nephelometers. His career exemplifies rigorous observational science that bridges local measurement campaigns with global climate implications.
