Modified Ecosystem Demography (ED2) model with sagebrush (shrub) parameters

<p># Original Ecosystem Demography (ED2) model was developed by Moorcroft et al., 2001 and Medvigy et al., 2009, and team, which is available at github (https://github.com/EDmodel/ED2).</p> <p># This&nbsp;repository contains modified Ecosystem Demography (ED2) model for sagebrush (shrub) PFT. In order to do so we primarily updated ed_params.F90 with additional PFT, which is represented by number &#39;18&#39;. For the initial works, we selected allometrics equations for temperate PFTs in ED2 to develop coefficients (parameters) related to&nbsp;allometric relationships (such as dbh to height , dbh to leaf biomass etc).&nbsp;We used cube root of volume to represent diameter to calculate allometric equations for shrubs, since they do not have clear main trunk like trees. Another source code&nbsp;ed_max_dims.F90 was also changed to update PFT dimensions.&nbsp;&nbsp;</p> <p># This repository also includes namelist (ED2IN) file used to run sensitivity and optimization of sagebrush parameters.&nbsp;</p> <p>References</p> <p>Medvigy, D., Wofsy, S.
