Xuhui Lee

Xuhui Lee is the Sara Shallenberger Brown Professor of Climate Science at Yale University's School of the Environment. He maintains offices at Kroon Hall (195 Prospect Street) and laboratory facilities at the Class of 1954 Environmental Science Center (21 Sachem Street, Room 300) in New Haven, Connecticut. Professor Lee is an active researcher and educator specializing in the interactions between the terrestrial biosphere, atmosphere, and anthropogenic drivers, with particular expertise in boundary-layer meteorology and climate science. He is currently on leave for the Fall 2025 semester but continues to accept doctoral students.

Professor Lee received his B.S.C. and M.S.C. from Nanjing Institute of Meteorology in China, followed by a Ph.D. from the University of British Columbia. His academic journey has positioned him as a leading expert in climate science, particularly in the areas of land-atmosphere interactions and urban climate systems.

Professor Lee's research focuses on boundary-layer meteorology, micrometeorological instrumentation, remote sensing, and carbon cycle science. His work examines biophysical effects of land use on the climate system, greenhouse gas fluxes in terrestrial environments (including forests, cropland, and lakes), isotopic tracers in carbon dioxide and water vapor cycling, and urban climate adaptation and mitigation strategies. His lab employs diverse methodologies including field observations (eddy covariance, optical isotope instruments, and greenhouse gas analyzers), mathematical models (land surface models, large-eddy simulation, WRF, and earth system models), and environmental remote sensing (satellites and drones). The Lee Lab investigates phenomena across multiple scales from micro (urban greenspaces) to global (land wet-bulb temperature, historical deforestation).

Analysis of Professor Lee's recent publications reveals a strong focus on urban climate systems, greenhouse gas emissions, and land-atmosphere interactions. His 2024-2025 work demonstrates increasing application of advanced remote sensing technologies and machine learning approaches to climate problems, with significant attention to urban heat islands, methane and CO2 emissions monitoring, and the impacts of land use change on climate systems. His research shows a clear trajectory toward more sophisticated integration of observational data with modeling approaches to address critical climate challenges.

Professor Lee actively mentors doctoral students and has established the Lee Lab as a hub for climate research at Yale. His lab group conducts field observations, mathematical modeling, and remote sensing analysis to advance understanding of climate systems. The lab's research infrastructure supports investigations from micro-scale urban environments to global climate patterns, with particular emphasis on urban heat mitigation and greenhouse gas monitoring.

The Lee Lab at Yale, located in Room 300 of the Class of 1954 Environmental Science Center, serves as the primary research facility for Professor Lee's team. The lab deploys an array of research methodologies including field observations with eddy covariance systems and optical isotope instruments, mathematical modeling using land surface models and earth system models, and environmental remote sensing with satellites and drones. The lab's research spans multiple spatial scales from micro (urban greenspaces) to global (land wet-bulb temperature patterns), addressing critical questions about climate change impacts and mitigation strategies.
