Hongyu Liu (NIA)

Title: Research Fellow
Technical Focus Area: Atmospheric Composition, Chemistry & Dynamics
Study TopicsAerosol sources and transport, wet scavenging of aerosols, Asian Tropopause Aerosol Layer (ATAL), radiative effects of clouds and aerosols on tropospheric photochemistry, sources and transport of tropospheric ozone


Hongyu Liu has over twenty years of experience in studying tropospheric ozone, cloud effects on composition, aerosol transport and wet scavenging using global chemical transport models (e.g., GEOS-Chem) in conjunction with ground-based, aircraft and satellite observations. He was involved in the NASA TRACE-P and EVS-2 NAAMES missions as well as the BATAL campaign. He is currently a member of the EVS-3 ACTIVATE mission science team. He was PI of several projects funded by the NASA ACMAP, MAP, and ACCDAM programs to study ozone sources and transport in Asia, investigate cloud radiative effects on photochemistry, constrain model aerosol scavenging parameterizations with radionuclide tracer observations, and develop physics-based scavenging parameterizations in the NASA GEOS Chemistry-Climate model (GEOSCCM).
