Not sure I understand your directory structure. Is it 
NAFP_T213_FOR_FTM/<month>/<day>? And the current month also contains a lastday/ 
directory?

From your catalog datasetScan, filter, and proxy:

  <datasetScan name="NAFP_T213_FOR_FTM Data" path="t213" 
location="/space/MetData/NAFP_T213_FOR_FTM/" >
    ...
    <filter>
      <include wildcard="*.nc"/>
    </filter>
    ...
    <addProxies>
      <simpleLatest serviceName="tdsserver" />
      <latestComplete name="latestComplete.xml" top="true" 
serviceName="tdsserver" lastModifiedLimit="60" />
    </addProxies>
    ...
  </datasetScan>

you should be getting a catalog for each directory under the NAFP_T213_FOR_FTM/ 
directory. Each directory that contains *.nc files should list those files and 
a "latest.xml" and "latestComplete.xml".

Is that what you are seeing? Are you getting any latest datasets in the 
NAFP_T213_FOR_FTM/ directory? I would guess you were not seeing the latest 
datasets there.

There isn't a way to tell the latest proxy datasets to scan a directory tree or 
look in a particular directory. It currently only deals with scanning one 
directory at a time.

Sorry, I don't have any other suggestions. Reorganizing your directory 
structure might help but I think you would have to collapse the entire 
<month>/<day> structure before the latest proxy dataset would give you what you 
want. And obviously that has plenty of drawbacks.
