For the single Band (single calibration), I default to the old style of 
parameter 
naming and did this so old bundles/formulas wouldn't break.  But you are correct
that this is problematic.  I this case the parameter name is actually
"M9 (10.8 um IR Surface/Cloud-top Temp)", the same as the Data Source 
description.
The description is 10.8 um IR Surface/Cloud-top Temp and what you see in
the list.

In the new version (when you select multiple bands or a single band with 
multiple calibrations), the parameter name is not Temperature, but 52_Band9_BRIT
using the convention we decided on.  Temperature is just the description that
gets listed in the selector.  I decided not to put in the band information
to the description since you would end up with something like this in the 
Field Selector:

0.6 um VIS Cloud and Surface Features
   0.6 um VIS Cloud and Surface Features - Raw
   0.6 um VIS Cloud and Surface Features - Radiance
   0.6 um VIS Cloud and Surface Features - Reflectivity
   0.6 um VIS Cloud and Surface Features - Brightness
0.8 um VIS Aerosols over Water, Veg
   0.8 um VIS Aerosols over Water, Veg - Raw
   0.8 um VIS Aerosols over Water, Veg - Radiance
   0.8 um VIS Aerosols over Water, Veg - Reflectivity
   0.8 um VIS Aerosols over Water, Veg - Brightness

if you select all units and/or all bands/all units.  It seemed that would
be overkill in the selection list.  Right now a Data Choice has a name
(e.g. 52_Band9_BRIT) which is the key used for derived parameters and is 
the default name used in display labels and a a description (e.g. Brightness) 
which is used in the Field Selector or as the long name in display labels.
Jeff and I talked about having a "label" which could be used in various
places (labels, etc).

In tomorrow's build, there will no longer be a composite choice shown as
"0.6 um VIS Cloud and Surface Features" with sub choices of times when you
select one band and one unit.  Instead, there will be a single choice
with a description "0.6 um VIS Cloud and Surface Features" with a name of
52_Band9_BRIT.  That way it will be consistent with the multiple band/multiple
unit selection.

There will also no longer be a choice for the Image Sequence Display since
this was tied to the composite choice.

I don't see any changes that should have fixed this so I don't know what's
going on here.  You shouldn't need that parameter any more with the new naming
scheme, though.  Let me know if this  still causes problems.
