[CF-metadata] New area_type table and new links from standard name table

Hello Alison,

A few weeks ago I had a question about representing land cover and Jonathan indicated that we should suggest new area-types on the mailing list.

The CRCM regional model uses "coniferous, deciduous, culture, herbs, and urban" cover types, plus bare soil. So I would suggest we add area-types for:

grassland
broadleaf trees (deciduous forest)
needleleaf trees (taiga / coniferous forest)
urban
agricultural / farmland

I'm not clear whether "bare soil" is the same as "bare ground" or whether it should have a separate area-type added as well. I don't know a lot about the details of this model (we're still waiting to hear from an expert), but I figured we could get the ball rolling.

Cheers,

--Seth McGinnis

>Dear All,

>Velimir and I have been working on creating the new table of
>standardized area_type strings as agreed under trac ticket 17.  The
>table lists the values permitted in variables with a standard_name of
>area_type.  To view version 1 of the table please go to
>http://cf-pcmdi.llnl.gov/documents/cf-standard-names/area-type-table/cur
>rent/area-type-table.  Clicking on the individual table entries will
>reveal explanatory text, although currently there is only help available
>for the two new floating_ice strings.  Please let us know if you have
>any comments about the format of the table.
>
>For ease of reference, there is also now a link from the area_type
>description text in the html version of the standard_name table to the
>new area_type table.
>
>At the top of the standard name table a link has been created to the
>standard name Guidelines document.  This has been done with the
>intention of giving greater prominence on the website to the existence
>of the Guidelines.
>
>The html copy of the standard name table has been rebuilt to add the new
>links, but this in no way affects the contents of the table which
>remains at version 11.  There are no changes to the xml version of the
>table.

>Velimir has converted the standard name Guidelines document to the
>docbook format (similar to the conventions document) and this hopefully
>will make it more navigable.  In addition, we have introduced version
>numbering of the Guidelines.  This is in response to the fact that there
>has been a number of recent changes to the document and it looks likely
>that there will be more in the future.  The Guidelines are currently at
>version 1 and this number will be incremented each time a change is
>made.

>If you have any comments regarding any of the above, please send them to
>the list.
