Hi Owen,

So, if 'FLEXPART' is a model, does it have output in grib format?
If yes, then the _much_ easier way to get the data into McIDAS format
is to run the grib decoder, gribdec.k.  Please let me know if the
model data is in grib format, and if you would like a step-by-step
guide for downloading the gribdec.tar.Z bundle and building the standalone
decoder.  It is easy to do and even easier to run.  The output will
be a McIDAS GRID, which is a better match for the data you have anyway.

This is very cool!

By the way, if the data is in grib format, you can use the routine
grib2img.k to turn it into an image; use gribdec.k to decode it into
a GRID; and even codisplay satellite images and CO images using
the IMGOLAY or FRMOLAY applications in Unidata McIDAS.


Please let me know if the FLEXPART data is, in fact, available in GRIB

Hi Tom,

No, the FLEXPART data are not output in GRIB format, but it looks like 
the TXT2MD method will work.

However, if you can look at the TXT2GRID command from SSEC and see if 
you can get it to work for UNIDATA Mcidas that would be great.
I really think that overlaying model ouput onto Mcidas imagery is going 
to become a routine operation for me and perhaps for many other folks, 
as visualizing pollution plume contours on top of IR imagery is the best 
way to understand long-range transport of pollutants.
