rsofun
A modelling framework for site-scale simulations of ecosystem processes, implemented as an R package (low-level routines in Fortran 90). Implements the following models:
- P-model for leaf-level acclimation of photosynthesis from Stocker et al. (2019).
- SPLASH for bioclimatic variables, including the surface radiation budget and the soil water balance from Davis et al. (2017).
- LM3-PPA for comprehensive simulations of ecosystem carbon and water cycling, tree growth, and tree cohort-explicit forest dynamics following the Perfect Plasticity Approximation, from Weng et al., (2015).
Installation
To install and load the rsofun package using the latest release run the following command in your R terminal:
if(!require(devtools)){install.packages(devtools)}
devtools::install_github("computationales/[email protected]")
library(rsofun)Problems with compilation? Make sure to have gfortran installed and paths to the compiler and libraries properly specified (see e.g., here).
Example
See vignette Example for using rsofun for how to run the model, and the ingestr R package for collecting the forcing data to run rsofun.
Usage and contribution
