Hi Rob:

Hi! Finally able to throw some more resources at setting up our TDS
server.  There are some interesting things going on that might be bugs or
might be some wet behind the ear struggling and would love guidance.

Queries:

1. Aggregation inside datasetFmrc
2. WMS GetLegendGraphic

----

1. Aggregation inside datasetFmrc

  <datasetFmrc name="Collections" path="fmrc/ROMS">
    <metadata inherited="true">
      <dataFormat>NetCDF</dataFormat>
      <documentation type="summary">JPL ROMS</documentation>
      <serviceName>all_services</serviceName>
    </metadata>
    <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>
      <aggregation dimName="time" type="forecastModelRunCollection"
recheckEvery="120 min">
        <scan location="/dp2/space/data/forecasts/ROMS/PWS/2009/raw/"
suffix=".nc" dateFormatMark="pws_fcst_#yyyyMMddHH" />
      </aggregation>
    </netcdf>
  </datasetFmrc>

change dimName="time" to dimName="runtime" , as "time" is already used for the 
forecast time

There is one more odd bit.

Going to the Opendap form and clicking on temp checkbox:

http://137.229.40.88/thredds/dodsC/dp2/data/forecasts/ROMS/PWS/2009/raw/pws_fcst_2009071306.nc.html

It does seem the grid is not recognized as the text boxes get filled in
with:
 time: 0:1:0  depth: 0:1:0  lat: 0:1:0  lon: 0:1:0

this is a bug in the opendap html form. ill try to get it fixed

2. WMS GetLegendGraphic, two items:

(a) packed vs unpacked data

For the above dataset, I have a packed and unpacked version (raw).  The
GetLegendGraphic is different between the two.

Packed:

http://137.229.40.88/opendap/wms/dp2/data/forecasts/ROMS/PWS/2009/07/pws_fcst_2009073106.nc.bz2?REQUEST=GetLegendGraphic&LAYERS=temp&LAYER=temp&PALETTE=redblue

Unpacked(raw):

http://137.229.40.88/opendap/wms/dp2/data/forecasts/ROMS/PWS/2009/raw/pws_fcst_2009073106.nc?REQUEST=GetLegendGraphic&LAYERS=temp&LAYER=temp&PALETTE=redblue

Are the scale and add offset attributes used?

im surprised theres any difference, since the bz2 file is simply unpacked to the 
"raw" form first

is "http://137.229.40.88/opendap/wms/"; the TDS ??
