The Pacala lab works side by side with the NOAA/GFDL Land Model Development Team, co-lead by Elena Shevliakova and Chris Milly (USGS). The LM4 Development Team designs and develops modules for the simulation of land-based physical, biological, and chemical processes relevant to climate, and configures those modules into realistic land models for studies in earth systems. It is part of the Atmospheric and Oceanic Science program, a collaboration between the Geophysical Fluid Dynamics Laboratory (NOAA) and Princeton University.
