About

Ina Tegen is a leading figure in aerosol-climate science, whose work has fundamentally shaped our understanding of how mineral dust and other aerosols interact with the Earth’s climate system. Her research focuses on the global modeling of aerosol cycles, with a particular emphasis on the emission, transport, and deposition of Saharan dust. Tegen’s major contributions include pioneering the evaluation of complex aerosol modules in global models, which distinguish between key components like sulfate, black carbon, and dust, as demonstrated in her highly cited 2003 study (324 citations). She has also been instrumental in validating dust transport models using observational campaigns, such as her work during the SAMUM 2006 experiment (63 citations), where she combined satellite data, lidar, and sun photometer measurements to track long-range dust plumes. More recently, Tegen has advanced the representation of Saharan dust sources in the ECHAM6-HAM2 climate model by integrating satellite observations of dust source activation (38 citations). Her achievements include leading model development for the SAMUM-1 campaign and contributing to the global AERONET network’s validation efforts. With a career dedicated to bridging model simulations and real-world observations, Tegen’s work is essential for predicting dust’s impact on climate, air quality, and biogeochemical cycles.
