<font face="Times New Roman">Dear Stephen,<br>
<br>
Here's some information that might provide a partial explanation:<br>
<br>
1. all 10 variables you list do indeed have the same same
standard name (area_fraction). The standard_name alone is *not
meant to* uniquely identify a variable (you need other metadata
attributes to do this). <br>
<br>
2. All but 1 (prveg) of the 22 standard names listed were not
agreed until early November 2010. So the CMOR tables did not
include a standard name for these variables prior to that time.
[Note inclusion of the standard_name attribute is not required for
CF compliance.] If IPSL wrote this output before November 2010
(or subsequent to that time used out-dated CMOR tables), then the
standard_name attribute will not appear in their files. <br>
<br>
Because of the above (and for many other reasons), a user should
be able to discover variables not only by searching on the
standard_name, but also the long_name or the variable name itself
(i.e., netCDF variable name). Does someone know whether anyone is
working on improving the search capability?<br>
<br>
We should at least make user's aware that only variables with
standard_names will appear in the current search.<br>
<br>
Best regards,<br>
Karl<br>
