TRACMASS is a Lagrangian trajectory code for ocean and atmospheric general circulation models. The code makes it possible to estimate water paths, Lagrangian stream functions (barotropic, overturning, etc.), exchange times, etc. TRACMASS has been used in studies of the global ocean circulation, of sea circulation in the Baltic Sea, the Mediterranean Sea and in coastal regions.
The code is written in FORTRAN 90 with modules and runs on UNIX platforms such as MAC OS X and Linux.
TRACMASS has been set up to run with velocities integrated with models such as NEMO or IFS-ECMWF, of satellite datasets such as AVISO.
What’s new in version 7.0
The current version of TRACMASS (v 7.0) includes the following new features:
- The code has been thoroughly cleaned up
Supported test cases from:
Ocean circulation models: NEMO, MOM5, ROMS Satellite ocean current data AVISO Atmospheric circulation model data IFS (ERA-Interim, EC-Earth)
- Any tracer can be followed e.g. biogeochemical tracers or chemical compounds in the atmosphere.
- A new quick-start guide and a comprehensive documentation.
