<p class=MsoNormal>Hi Renata and Giri,<o:p></o:p></p>
<div>
<p class=MsoNormal><span class=apple-tab-span> </span>thanks for the
spreadsheet, we should encourage all people who will be providing obs to CMIP5
to take a look and add their contribution.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I do have a question: the obs table is now called
"obsSites". Is this meant to also include remote sensing datasets, or
just station data ? Should we have a collection of CMOR obs tables ?<o:p></o:p></p>

<p class=MsoNormal>Everyone with the url can modify it, so maybe we need to use

<p class=MsoNormal>The observational table itself is in a tab named 'obsSites'
(you may need to scroll to see it or use navigational arrow in the tabs menu to
see more tabs). It's mostly a copy of cfSites but with modification for the
obs. specifications. This is just a beginning, we will be adding more
variables, as needed, please do add the variables that your data requires.
Notice that all the 2D variables from Amon are part of this table, with the
modification in time cell method (which now allows instantaneous (time:point)
and time average (time:mean) measurements with any time average
interval). <o:p></o:p></p>

<p class=MsoNormal>Hi all,<br>
<br>
yes I think as well those attributes can describe the nature of the link
between raw measurement and used product.<br>
Taking an example I know:<br>
<br>
<span style='color:black'>- CALIPSO-GOCCP is derived from Calipso L1/NASA
products (NASA Langley ASDC - CALIPSO Data Sets).</span><br>
- A piece of code is applied on L1 product to produce an information directly
comparable with gcm outputs (and COSP package).<br>
- This piece of code and the underlying reasoning have clear identifier and
references (doi).<br>

<p class=MsoNormal>Thinking about that it could be good to add as well a
citable reference in the global attribute. I'm sure all observational dataset
will have one. Just a suggestion.<br>
