Dear Karl,<br>
<br>
the file we published on ESG where originally created using "23
August 2010" or "30 November 2010" tables. <br>
<br>
But we rewrote them using "31 January 2011" tables where necessary.<br>
<br>
For example *all* our land variables has been rewritten using 31
January 2011 tables. So *all* our land files have standard name in
it.<br>
<br>
I don't know how gateways feed their standard names database. But it
could be that they use CMOR2 tables and not the metadata coming from
the files. This could be another explanation.<br>
<br>
------------------------<br>
creation_date = "2011-01-08T01:50:31Z" ;<br>
history = "2011-01-08T01:50:31Z CMOR rewrote data to comply with CF
standards and CMIP5 requirements." ;<br>
table_id = "Table 6hrLev (30 November 2010)
6c116423753a0c320c0cf3e31acd51b9" ;<br>
------------------------<br>
creation_date = "2011-02-23T17:56:33Z" ;<br>
history = "2011-02-23T17:56:33Z CMOR rewrote data to comply with CF
standards and CMIP5 requirements." ;<br>
table_id = "Table Lmon (31 January 2011)

<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>
