Project Title: "Effects of Future Changes in Climate and Atmospheric Composition on Forest Ecosystems across the Northeastern U.S.: Model Development, Testing, and Projections"
In support of this project, the suite of PnET models has been rewritten in a 4th generation programming language (MATLAB) in order to facilitate the structural additions proposed in this work and reduce the effort required to produce large spatial simulations and output visualization. PnET has always been a public model and the newly developed code base is available on the website (http://www.pnet.sr.unh.edu).

Project Title: Evaluation of ecosystem carbon dynamics in North America Using Hourly to Decadal Data on Local to Regional Scales
We propose to combine two different data sources (eddy flux, forest inventories) to estimate biophysical parameters with an emphasis on respiration parameters, for the state-of-the-art dynamic vegetation model LM3V.
