gx3v7 missing in pop_obs_data_20100331?

[eros_albertazzi@cmcc_it]

I am trying to run popdiag_rel_20100331 on model data produced by cesm1.0 on gx3v7 grid.
But in pop_obs_data_20100331 data for that grid are missing.
Any clue on what to do?

Hi, I am the ocean model science liaison here at NCAR and do upkeep for the ocean diagnostics. From what I can tell, the data you may be missing is the sea surface height and the 2D surface flux and wind fields. The script will still produce some of the surface flux plots, but the difference with observations will be off because it's trying to use a 1-degree observations file to compare to. With sea surface height, the plot just won't be created. Currently, I am unaware of observations for these fields here at NCAR on the gx3v7 grid. This means that the diagnostics script will not produce these particular plots.

Please write back if there were other files you may be missing. Just a heads up....there will be a new diagnostics package posted within the next couple of weeks. It should be a bit more user friendly and contains a new plot or two.

thanks so much for the reply. I'll keep my eyes open for your new release.
I am rather ignorant on pop and my wonder concerned data files (and a string in a ncl script) on the gx3v5 and v6 vs. v7 grids, all present and mixed in the distribution.
I presume, although the resolution is the same, the grids are different and there is more that just a different name

When the ocean model is run, it uses one of these grids (gx3v7, gx3v5, etc.). In order to match this grid when running the diagnostics, you'll need to know what grid the model output you are using is. Many of the changes between different versions (v3 vs. v5) of the same grid are changes in bottom topography or land mask changes (though there could always be other changes), so yes, there is a reason for the name change. You could still run the diagnostics with a different version than your output, but you might end up with some strange points in the difference plots with observations based on these grid differences.
