Hello, I think the unit specified in comments for rcp here is wrong. IMO it should be \[J/(kg\*K)\], not \[J/K\]. The value is OK though. This has no implications whatsoever on the actual model, but I think it has some for …

Dear users, I’m trying to compile the default configuration of the latest version of NEMO 4.2.0 and got the error message catastrophic error: \*\*Internal compiler error: internal abort\*\*. I’m using Intel fortran version…

Dear All, Just to know if someone has used outputs of trends produced by trd\_tra in routine trazdf.F90. I really think there is a bug somewhere as these trends are un-realistic (very high). Any idea or opinion is welc…

Hello everyone, I need to implement a particular tracer diffusion scheme, with a fully anisotropic and location dependent diffusion tensor. Right now I coded it with a “brute force” approach, coding it from scratch foll…

Hello, running some technical tests with ORCA2 and NEMO 4.0.6 we realized that after a few months tracer output fields become unrealistically noisy in the Tropics west off South America (see figure attached for 5-daily …

Hi all, I am using the TEOS-10 in a regional configuration of NEMO4.0.6. It is clear that the model should be initialised with the conservative temperature and absolute salinity. If we use TEOS-10, does the tracer field…
