SAMSIM
|
V1.0 of this model was developed from scratch by Philipp Griewank during and after his PhD at Max Planck Institute of Meteorology from 2010-2014. Most elements of the model are described in the two papers "Insights into brine dynamics and sea ice desalination from a 1-D model study of gravity drainage" and "A 1-D modelling study of Arctic sea-ice salinity" of Griewank and Notz" which are both included in the repository. V2.0 of SAMSIM is a minor expansion of V1.0 released in 2018. Most work was done by Niels Fuchs as part of his Master's thesis "The impact of snow on sea-ice salinity" at the Max Planck Institute of Meteorology from 2016-2017 (thesis also in repository). The biggest change is an improvement of the flushing parametrization, as well as the settings and forcings for a large amount of laboratory experiments Niels conducted, making it possible to run lab testcases with snow.
SAMSIM.f90 is the root program of the SAMSIM, the 1D thermodynamic Semi-Adaptive Multi-phase Sea-Ice Model. However, in SAMSIM.f90 only the testcase and description thread are specified, which are then passed on to mo_grotz, which is where most of the actual work is done, including timestepping. The code is intended to be understandable and subroutines, modules, functions, parameters, and global variables all have (more or less) doxygen compatible descriptions. Both a pdf and html documentation generated via doxygen are included under documentation.
WARNING: SAMSIM was developed and was/is used for scientific purposes. It likely contains a few undetected bugs, can easily be crashed by using non-logical input settings, and some of the descriptions and comments may be outdated. Always check the plausibility of the model results!
Getting started:
Running SAMSIM the first times.
Running testcase 4.
Following modules have a good documentation (both in the code and refman.pdf)
Biogeochemical tracers can be activated with bgc_flag=2.
