About
J. A. Hansen is a leading figure in atmospheric aerosol science, whose work has fundamentally advanced the operational prediction of aerosols on a global scale. His primary research centers on the development and evaluation of multi-model ensemble systems for aerosol forecasting, a critical area for understanding air quality, climate forcing, and weather interactions. Hansen’s most significant contribution is his leadership in the International Cooperative for Aerosol Prediction (ICAP), where he spearheaded the creation of the ICAP Multi-Model Ensemble (ICAP-MME). His seminal 2015 paper, which has garnered over 132 citations, established the basic climatological characteristics of this ensemble, demonstrating how combining outputs from multiple operational models yields a more robust and reliable aerosol consensus than any single model. This work laid the essential groundwork for transitioning aerosol forecasting from a research tool into a quasi-operational capability used by major weather centers worldwide. By providing a foundational framework for global aerosol consensus, Hansen’s research has profoundly impacted both the scientific community and operational forecasting, enabling more accurate predictions of dust, smoke, and pollution transport across the planet.
