Dr. Lan is a carbon cycle scientist with the Cooperative Institute for Research in Environmental Sciences of University of Colorado Boulder and NOAA Global Monitoring Laboratory. Her research focus on the carbon cycle and greenhouse gases, with a particular focus on understanding the sources and sinks of CH4 and other long-lived greenhouse gases (LLGHGs).
Dr. Lan is the scientific PI of discrete atmospheric CO2, CH4, N2O and SF6 measurements at over 50 sites in NOAA’s Global Greenhouse Gas Reference Network (GGGRN). She leads the reporting of NOAA’s global CO2, CH4, N2O and SF6 trends. She also serves as a Subject-Matter Expert for communicating greenhouse gas measurements and research findings with a wide range of audience including students, journalists, and the public. Dr. Lan is a member of the World Meteorological Organization’s Science Advisory Group for Greenhouse Gases.
