I will definitely do 2.<br>
<br>
Also I will edit the tables to set these min/max for monthly tables
only.<br>
<br>
I will see if I can run the script for other frequencies as well.<br>

<p class="MsoNormal"><font size="3" color="black" face="Times

mentioned, I got the max/min from looping over
20c3m models "monthly" in AR4.<br>
<br>
If anybody as better values please forward them to us
we'll gladly put them
into the tables.<br>
<br>
If anybody's interested I can search the code I used to
search through the whole
AR4 archive.<br>

<br>
I'm copying Charles D. who I hope will check the
following for
correctness. As I recall:<br>
<br>
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.)<br>
<br>
Charles can tell you how he got the "max" and the "min"
that appear in the table.<br>
<br>
regards,<br>
Karl<br>
