[McIDAS #TSV-261063]: Using McIDAS-V to access SSEC's Open Archive

Hi Jane,

re: - does the contents of your Edit Remote Dataset window look like the
image I attached?

OK, this is very weird indeed.  Unfortunately, I can't diagnose anything
from here, so we have to move to Plan B...

Here is the first big problem: there is no one satellite that provides
coverage over your region of interest:

- the sub-satellite point for MTSAT is 140E; the sub-satellite point
  for GOES-11 was 140 W

  GOES-West and MTSAT images could be composited together to give the
  desired areal coverage: 120E - 120W; 60S - 0S 

- the composites would not be seamless as the wavelengths for the various
  channels are slightly different:

  MTSAT       GOES-West   Channel
  -----------+-----------+---------
  0.73 um      0.65 um    VIS
  6.75 um       6.8 um    WV
  10.8 um      10.7 um    IR

The process for creating the coverage you want would then be:

- create an image that has the coverage desired

- remap MTSAT into that coverage

- remap GOES-West into the remap of MTSAT

- do this for every wavelength channel and time step desired

- display each composite and capture a GIF

- post the GIF to a machine where you could access the images

This will take some time given the large number of cases that
you have listed:

I am not sure that all of this work can be accomplished by
Wednesday morning.

Would it be possible for you to:

- settle for one wavelength channel instead of all 3?

- settle for one composite every 6 hours?

- prioritize your cases so that the most important ones
  get done first?

Just a comment: it would been a good idea to start working on this
over the past weekend...

Cheers,

Tom
