Re: 20120619: Change longitude where data from 2 geostationary satellites are merged together



Tom,

Thanks for the idea.  However, I need data from early February of this year, 
and (if I'm looking at the right stuff on adde), it looks like your composite 
images are only for the past several hours.  Is that correct?  I'm going to try 
Don's jython script to see if it will work for me—I'm guessing it will.

Thanks again for the help.  I really appreciate it.
