Improvement of CLM4-CN by using N-limited GPP for determination of stomatal conductance, and comparions to observed runoff values from GSWP2 (Global Soil Wetness Project 2). Evaluations of CLM4-CN control and downregulation with GSWP2 for total runoff (mm/year), a) FLUXNET MTE, b) Control, c) Control – FLUXNET MTE, d) Downregulation – Control.

Climate Modeling

I have specific modeling experience with general circulation models (GCMs) and regional climate models (RCMs). Most of my research with these models has focused on paleoclimate simulations and data-model comparisons, especially during the Holocene and Last Glacial Maximum (LGM). I used the National Center for Atmospheric Research (NCAR) Community Climate Model Version 1 (CCM1) to explore the sensitivity of the climate system to different forcing mechanisms, such as ice sheets, orbital insolation, and atmospheric CO₂
