@Ovewh - I think you need to do this in parallel and I think writing a routine in fortran that leverages ESMF and PIO to do this would solve the...

@IngoBethke @Ovewh - one big advantage of using the type of fortran routine I'm proposing is that you never have to generate the mapping files - the weights are generated...

@IngoBethke - just to clarify a bit more. CDEPS ((https://github.com/NorESMhub/CDEPS) has an inline API (https://escomp.github.io/CDEPS/versions/master/html/streams.html#data-model-stream-inline-api) such that data can be read in from multiple files and interpolated both spatially and...

@IngoBethke - with the branch I have provided @Ovewh - we no longer need to do any horizontal interpolation on the input nudging fields and we no longer require to...

@mvdebolskiy - in looking at the cprnc output for your failed test - ``` ERS_Ld766.ne30pg3_tn14.N1850.betzy_gnu - I see the following (see below). This would point to a non-bfb difference in...

@mvdebolskiy - several points: - I am noticing with your test is that you are not writing restarts at the yearly boundary for Ld766. Your restart is at 0002-01-20-00000. So...

I have done a simple test using the following (see below) and obtained bfb results with restarts across the year boundary ``` ./create_newcase --case /cluster/home/mvertens/noresm/nf2000_restart_test --compset 2000_CAM70%LT%NORESM%CAMoslo_CLM60%SP_CICE%PRES_DOCN %DOM_MOSART_DGLC%NOEVOLVE_SWAV --res ne30pg3_ne30pg3_mtn14...

@monsieuralok @mvdebolskiy - I cannot duplicate the problem that @monsieuralok found. I used the exact same setup and the only difference I had was that use_aerocom = .false. - however...

@monsieuralok : I am **only** comparing the two ATM-LAND runs at this point - not the fully coupled. So the comparison should be with your cases ``` /cluster/work/users/agu002/NorESM3_alpha2/cases/nf2000_ne30pg3_ne30pg3_mtn14.fatessp_A2T1 /cluster/work/users/agu002/NorESM3_alpha2/cases/nf2000_ne30pg3_ne30pg3_mtn14.fatessp_A2T2 ```...

@mvdebolskiy - did this test pass with alpha02a? Does the test with intel pass?
