Note, the file names denote the model initialization time.
For example, a model run initialized on December 1, 2000 at 00z:
	00120100.1mm5.gem
(yymmddhh.#mm5.gem)

The 1mm5 file covers the larger (outer) domain which is set at a
	resolution of 90 km.
The 2mm5 file covers the smaller (inner) domain which is set at a
	resolution of 30 km.

One file for each of the domains is created for each model run.

The vis5d file created for each run is for the larger domain only.

We will be keeping data for download from model runs that occured within
the past 48 hours.
