Andrew GettelmanView profile
Researcher
Andrew Gettelman is a distinguished climate scientist at Pacific Northwest National Laboratory whose research spans atmospheric sciences, climatology, and climate modeling. With a D-index of 91 and over 32,652 citations across 343 publications, he ranks 422nd globally and 194th nationally in Environmental Sciences. His research interests focus on fundamental climate processes including cloud microphysics, aerosol-cloud interactions, stratospheric dynamics, and climate model development. Gettelman has made significant contributions to understanding Arctic climate feedbacks, particularly how clouds respond to sea ice loss, and has advanced the representation of aerosols in climate models through his work on the Community Atmosphere Model (CAM). Analysis of his publication trends reveals a consistent focus on improving climate model representations of atmospheric processes, with recent work emphasizing climate sensitivity in the Community Earth System Model (CESM2) and bounding global aerosol radiative forcing. His research bridges fundamental atmospheric science with practical applications for understanding climate change. Among his recognitions, Gettelman has been named to the World's Best Scientists 2025 list. His highly cited works include foundational papers on cloud microphysics schemes and aerosol representation in climate models. Gettelman maintains extensive collaborative networks, frequently working with researchers from the National Center for Atmospheric Research, University of Colorado Boulder, and other leading climate institutions. His research has been instrumental in advancing climate modeling capabilities used in major international climate assessments.
