Domain configuration tool to implement sigma coordinates under ice sheets.


This code would use the idea of envelop bathymetry 'turned upside down'. An appropriate interface sigma level is chosen to continue from the open ocean to under the ice sheet. All shallower sigma levels are 'beached' in the ice sheet.


Code to be developed as part of DOMAIN CFG Tools

This work ended up being delayed as several modifications to the ISF code were required. Work on the ISF code was being carried out under a separate WP2019 ticket and any code changes made for this work were passed on to Pierre.

As this development was being carried out in conjunction with the ORCHESTRA project (and we were under time constraints), I just had to press ahead with developing a project specific pre-processing code, written in Python (along with ad-hoc changes to the ISF code) in order to progress the project.

The Python code can be made available and if there is the desire can be added to the configuration tools as part of WP2020.

Note: See TracTickets for help on using tickets.
