Ocean Modeling Discussion

Hi, We (NOAA National Centers for Coastal Ocean Science) are hiring a postdoc in numerical modeling focusing on HABs. The postdoc will be through ORISE postdoctoral fellowship program with generous stipend and health insurance subsidy. https://www.zintellect.com/Opportunity/Details/NOAA-NCCOS-2022-0...

Thanks John, and will email James for it.

liyizhen: LTRANS v1 It speeds it up a LOT though the testing was not thorough. A normal run formerly took around 30 hours. With mpich it took an hour and a half or so. John, that sounds a great speeudup! Please let me know when your friend is willing to share the code. We've been using LTRANS for o...

John, can you tell me your colleague parallel ltransv2 or v1. It would be interesting to see how fast it can speed up the computation!

Thanks Kate.

I encountered the same problem when using ncatted. Where is the null value from Kate?

The way to know for sure is to search for that string in the source files and see what's there. Thanks Kate. It appears in ana_grid only, and it's only used in analytical grid applications. Functionals/ana_grid.h:#ifdef SPHERICAL Therefore in WC13 4DVAR experiment, SPHERICAL option was not really t...

Hi, I just saw that in the data assimilation flag WC13, there is a cpp definition #SPHERICAL turned on. In cppdefs it mentions "use if analytical spherical grid". Obviously it's nothing associated with the flag spherical in the grid file, which is a flag for if it's in realistic lon,lat co...

Thanks Hernan!

Hi, I'm running a climatological simulation using ROMS version: September 24, 2010 The simulation is smooth, and I didn't see any problem in the grid mask file (mask value==0 or ==1). However, in the output avg files, the mask_psi is ==2 for some locations. I am supposing this is just an output erro...

Haibo,
Is it caused by DT/DTFAST too large?
CFL condition satisfied yet?
