After a quick skim of that article, I'm not sure why you sent it. It doesn't mention 33X, and only,

But the data I have is referenced to WGS 84. It is UTM 33X, which is 72°N to 84°N, and is 12° wide, from 9° to 21°.

There is none that I can find.

I'm not sure what you mean by "define a GRASS location for this area for your own". I think I've done that (or more correctly GRASS has done that):

grass70 -text -c -e file.grid ./grass/foo
grass70 -text ./grass/foo/PERMANENT
r.import input=file.grd output=f

I have a grass location. The data is imported. I can do analysis on it and visualize it. But being a newbie to grass, I don't know how to get it out of this location and into another location for analysis that requires other data.

Because 33X is well defined (see my description above, based on this map http://www.dmap.co.uk/utmworld.htm ), I assume it is possible to export or reproject it to a different location, but being a newbie I don't know how to do this in GRASS, hence these emails.
