[McIDAS #PXP-840815]: Re: Problem converting to netCDF with McIDAS

Hi Greg,

re:

Hmm...  Ah Ha, I see why it was not driven into our inquiry tracking
system - the size of the message with the attachment (13644390 bytes) exceeded
the 2M limit that our inquiry tracking system imposes.  We received the
message, and it got put into the pipeline that forwards it to our inquiry
tracking system, but it did not get into the inquiry tracking system due
to its size, and this is the reason that you did not get the auto response.
Mystery solved...

I've got the file named g13.2015155.0200.nc.

OK.  Nothing jumps to mind immediately.

What is the projection used in the template?

OK.  Did you check to make sure that the AREA file created by 'remap2' was
viable (meaning that you could display it, draw a map on top; and the
image features looked reasonable/correct)?

I don't know off hand.  It would be helpful if you provided the exact
procedure that you used and one original image so that I can try and
work through the procedure exactly was you did, so I can see what, if
anything, is wrong.  It might be easiest if the original image and
the  AREA file created by 'remap2' was put in a directory that is
accessible to me on typhoon.


Cheers,

Tom
