Soundings in GrADS - Problem

[Dan Swank]

All,

Apologies for not posting this earlier...
We have identified a problem with the date mappings in the grads binary
files we posted with the IGRA data.  The data for each sounding is
accurate however grads is associating them with incorrect dates.
So we have taken down this dataset until the problem is resolved.

Hope to have it back up within the week.

-Dan
