[Met_help] [rt.rap.ucar.edu #71589] History for Parallax Issue

[John Halley Gotway via RT]

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

Dear John,
I'm Michele: do you remember me? I write you for a question. I'm working
with geostationary satellite data and my binary field has a parallax issue.
Is it possible to correct it using MODE in some way?

Thanks a lot

Best Regards

Michele

Hello Michele,

I created a new MET-Help ticket for this issue rather than attaching
it to your previous question.  Please just reply directly to this
email, rather than the old one.

I see that you have a parallax issue with your geostationary satellite
data.  I've got to say, this is unique question... first time I've
seen it in MET-Help!

Unfortunately the answer is no.  The MET tools don't include any
functionality that would help you with that.  That's a pre-processing
step that would occur upstream of running MODE.

In the United States, when NASA produces satellite data, it's
available at several "levels", such as Level 1, Level 2, and Level 3.
The higher the level, the more post-processing and error-correction
have been applied.  Presumably, that would include correcting for
things like parallax error.  And many of those algorithms would be
very specific to each instrument.

I'd suggest going back to the source of the satellite data to see if
they have a more highly processed version of the data.

Thanks,
John Halley Gotway

OK John,
thanks a lot. I think to have solved by modifying the convex_hull_dist
parameter.

Best Regards

Michele
