About
Kostas Tsigaridis is a prominent atmospheric scientist whose research centers on aerosol modeling, climate interactions, and Earth system science. Based at NASA's Goddard Institute for Space Studies, he has made significant contributions to understanding how aerosols — from desert dust and sea spray to biomass burning particles and brown carbon — influence regional and global climate systems. Tsigaridis is perhaps best known for his involvement in large-scale multi-model intercomparison initiatives, particularly through the AeroCom (Aerosol Comparisons between Observations and Models) framework. His collaborative work evaluating aerosol distributions over South Asia (149 citations) and North African dust transport across the Atlantic (135 citations) has helped identify systematic model biases and their underlying causes, directly improving the reliability of climate projections. His expertise extends to sea spray aerosol characterization (60 citations) and satellite-based evaluation of biomass burning aerosol representations in global models. More recently, Tsigaridis has pioneered the incorporation of brown carbon — a poorly understood light-absorbing organic aerosol — into the GISS ModelE Earth system model, advancing understanding of its radiative effects. His work on iron oxide composition in mineral dust further refines estimates of dust's net cooling effect on climate. Across his career, Tsigaridis has consistently bridged observational data and computational modeling, producing research essential for both climate science and air quality policy.
