[IDV #TTT-288053]: Attempting to load point data into IDV

Greetings Eddie,

No problem on the delay - I can appreciate being busy :-)

You can combine multiple GRIB files via the IDV data chooser. From the 
Dashboard,
select the Data Choosers tab and select "Files" from the left hand panel. Then, 
find
the location of the GRIB files on disk, and hold ctrl (Command on Mac) and 
select
all the files you are interested in loading. Then, under Data Source Type, 
select
"Aggregate Grids by Time". Finally, click Add Source. If all goes well, all of 
the
GRIB files you selected will show up as one data source under the Field 
Selector.

Let me know if that works for your files. Cheers!

Sean
