[Datastream #YAT-522314]: HRRR 3K data grid request...

cool project!

Not sure exactly....we have the full 2D HRRR feed from NOAA/GSD. Honestly, we 
have had the feed
for a few months and have not had the resources to fully explore the 
contents.....there is ALOT
in there :)

Doing a casual sniff of the feed via our LDM's 'notifyme' command i see many
products and do see:

Jan 02 22:00:25 notifyme[13317] INFO:  1183328 20130102213235.825
RIB2.FSL.HRRR.1905141_Lambert.012Hour.Vis.Surface.201301021900.*

..I suspect the others are there, it is a voluminous feed (~1.2GB/hour). We can 
diminish that by requesting
only the parameters you desire. The only method of delivery we currently 
support for this data is our LDM, please see:

Mark  Wysocki is currently running the LDM at Cornell, not sure if you 
know/work with him, but it is generally
a good thing to leverage your resources if you can.

Do you know how the parameters you desire will be represented in the model 
output? If so I can be more exhaustive
in my search for your desired fields (i.e. by machine instead of human).

Happy to feed you the data, I will look more deeply into the feed looking for 
your specific cloud parameters
to see if I can find them, and if you know how the model output is formed, that 
will make the search easier
You/we will need this information anyway to pare down your request via the LDM 
(using regular expressions) and its' request line to conserve bandwidth. ;)
