C++11-Implementation of the Acclimate model by Sven Willner and Christian Otto.

The newest ("price") version of the Acclimate model is described in (please cite when using this code):

• Otto C, Willner SN, Wenz L, Frieler K, Levermann A. (2017). Modeling loss-propagation in the global supply network: The dynamic agent-based model acclimate. Journal of Economic Dynamics and Control. doi:10.1016/j.jedc.2017.08.001.

You need to have CMake installed for compiling the source code (under Ubuntu-like Linux distributions: sudo apt-get install cmake).

External dependecies:

• NetCDF C
  • used for reading and writing of NetCDF files
  • Source code: Unidata/netcdf-c
• NLOpt
  • used for numerical optimization
  • will be built in by default
  • Source code: stevengj/nlopt)
• YAML-cpp
  • used for reading settings files
  • will be built in by default
  • Source code: jbeder/yaml-cpp

Further built-in dependecies (included in this repository as subtrees):

• swillner/cmake-modules
  • used for compilation
• swillner/cpp-library
  • some minor helper functions, e.g. for progress bar
• swillner/netcdfpp
  • used for reading and writing NetCDF files
• swillner/settingsnode
  • used for reading settings files

Have a look at the CMake documentation of how to invoke CMake on your system. On a system using the make command, simply run:

mkdir build
cd build
cmake ..
make

Further configuration can be done before running make e.g. using ccmake ...

Multi-regional input-output is used by Acclimate to build-up the baseline economic network. Such data is not included in this repository. In the publications mentioned above the EORA dataset was used.

Acclimate expects a configuration YAML file whose path is given on the commandline when running Acclimate. An example is provided in example/settings.yml.

For information about the built binary run:

./acclimate -i

This implementation also includes the older "basic" and "demand" versions. These are described in:
