[Go-essp-tech] ok_min_mean_abs and ok_max_mean_abs

[Karl Taylor]

Hi Denis,

I'm copying Charles D. who I hope will check the following for 
correctness.  As I recall:

The mean_abs value is the temporal and spatial mean of the absolute 
values of a field (based on latxlon grid cell values, but not area 
weighting these).  The mean_abs value specified in the CMOR tables is 
based on monthly means produced by CMIP3 models.  It basically gives you 
the typical magnitude of the values of the field.  If a model has a 
number much smaller or much larger than the CMOR table value, then it 
may be unrealistic (or if off by an order of magnitude or more, it 
probably means the units are wrong.)

Charles can tell you how he got the "max" and the "min" that appear in 
the table.

regards,
Karl
