Pull Request Notes

Summary

Details

  • Updated volume definition to vol = dxdy(ib,jb) * dzt(ib,jb,kb,nsm) * zstot(ib,jb,0) when nqua=3 so particles reflect fraction of total grid cell volume at seeding time.

  • Update ntracmax definition in mod_seed.F90 when nqua != 0 to ntracmax = nsdMax*nsdTim*nsdtraj where nsdtraj is a user specified parameter in the namelist file in the &INIT_SEEDING section.

  • Add existing l_compress option to the namelist, enabling compression of large _run.csv output files which exceed 2 GB using gzip.

Additions have been tested with the Theoretical and NEMO example cases on the JASMIN HPC, UK.
