TROLL 4.0 is an individual- and trait-based model of forest dynamics. A full description of the model and discussion of the underlying modelling choices can be found in the following manuscript:
“TROLL 4.0: representing water and carbon fluxes, leaf phenology and intraspecific trait variation in a mixed-species individual-based forest dynamics model – Part 1: Model description. Maréchaux I, Fischer FJ, Schmitt S, Chave J” currently in an open review process for Geoscientific Model Development.
The following command line can be used to compile the code:
g++ -O3 -Wall -o TROLLv4_exe main_TROLLv4.cpp -I GSL_PATH/include -L GSL_PATH/lib -lgsl -lgslcblas -lm
GSL_PATH must point to your local GNU Scientific Library (GSL) installation, see https://www.gnu.org/software/gsl/
The code of TROLL 4.0 is written in C++ and requires five input files to run a simulation: (i) global parameters (global_inputs), (ii) species parameters (species), (iii) soil characteristics (soil), and finally, meteorological drivers varying at (iv) half-hour (halfhourly_climate) and (v) daily step (daily_climate).
The following command line can be used to run the code:
./TROLLv4_exe -i./example/global_inputs.txt -s./example/species.txt -m./example/daily_climate.txt -d./example/halfhourly_climate.txt -p./example/soil.txt -o./TROLLv4_test
TROLL 4.0 can be set-up and run, and its outputs can be analyzed with an updated version of the R package rcontroll (https://github.com/sylvainschmitt/rcontroll/tree/TROLLV4), also available in R through the command:
devtools::install_github("sylvainschmitt/rcontroll", ref = "TROLLV4").
The package also provide examples of input files and outputs.
