Jinxun Liu
Dr. Jinxun Liu is a Research Ecologist with the Western Geographic Science Center at Moffett Field, CA. His research interests and expertise are closely related to system ecology and ecosystem simulation models.
Jinxun began agro-forestry system modelling and performed system optimization on tree harvesting during his PhD study. Starting in the late 1990s, he began carbon simulation studies. He has used many models in his research, such as the CBM-CFS2, 3PG, TreeDYN3, CENTURY, TRIPLEX, IBIS, GEMS-EDCM, USPED, and LUCAS. His other skills include GIS/RS data processing, NetCDF data processing/visualization, artificial neural network modeling, and leadership class supper computing (ALCF Mira/Theta, NERSC Cori/Perlmutter). His research activities have resulted in more than 60 peer-reviewed journal publications.

Federal lands greenhouse emissions and sequestration in the United States—Estimates for 2005–14
In January 2016, the Secretary of the U.S. Department of the Interior tasked the U.S. Geological Survey (USGS) with producing a publicly available and annually updated database of estimated greenhouse gas emissions associated with the extraction and use (predominantly some form of combustion) of fossil fuels from Federal lands. In response, the USGS has produced estimates of the greenhouse gas emi
