#226 closed error (fixed)

error when running a LAM

Description

I have tried to do some experiments with the nesting procedure but in an area in West Africa, I succesfully run a global experiment from which I generate the LBC for the LAM at 12 KM, following the procedures from the example of nested LAM runs, I got the respective ancillary files and apparently I set up the same horizontal/vertical dimensions, I already got the LBC, I used my own dumps, and everything seems to be fine, but I got the next error message.


Reading in Ancillary Land-Sea Mask

Hi Carolina,
You seem to have hit a very annoying problem: a consistency check in the UM has failed because 3.75E-7 is not sufficiently close to zero! It seems you may have to re-create the ozone ancillary file again. See section 4.7.4 of the UM 5.5 User's Guide last paragraph:

"Make sure you enter values to exactly the same precision as you will use in the UMUI when setting up experiments. Otherwise your runs may fail internal consistency checks in the model."

I think the value in question is the first latitude of the domain which is meant to be zero but has come out at 3.7E-7.

I will continue to look at this.

Regards,

Willie

Hi Carolina,

I have talked with Grenville about this and he suggests that you move the edge of the LAM off the equator slightly e.g. by making it 0.5 degrees. Thus you need to re-create the ancillaries with this new LAM.

Let me know how you get on with this.

Regards,

Willie

Hi Willie:
I already re-created the ancillaries as suggested, when I check the files using xconv dimensions seems to be according to the dimensions I submit either in the ancillary program creator and in the model, but now I'm getting the next error.

the job is in /home/n02/n02/carito/work/xdtcb and it already have open access permission.

I would appreciate if you have a look on it to find out what is going wrong, thanks.

Hi Carolina,

Sorry about this. It is the same problem. The threshold being used is 1.0E-6 and your 0.5 value is just failing. Could you re-create the ancillaries with 1 degree first latitude and re-run, please?

Regards.

Willie
