[ldmMcidas #PVL-726977]: goes 10 imagery

Hi Waldenio,

Wonderful!  Is the navigation now correct?

I agree.

Yes.

I use the output from the ldm-mcidas package routine 'area2png' as
the product ID.

Here are the meanings for these fields:

Qx - this defines the quarter of the hour of the image's nominal time:

     Q1 - some sort of hourly image (once per hour, two hours, three hours, 
etc.)
     Q1 - H+00 - H+15
     Q2 - H+16 - H+30
     Q3 - H+31 - H+45
     Q4 - H+46 - H+59:59

pd - this is a McIDAS routing table product code.  We should standardize on the
     product codes to use.  My first thought is:

     SV - full disk visible     (0.65 um)
     SS - full disk short IR    ( 3.9 um)
     SW - full disk water vapor ( 6.8 um)
     SI - full disk thermal IR  (10.7 um)
     SL - full disk long IR     (12.0 um)

     S1 - 15-minute visible     (0.65 um)
     S2 - 15-minute short IR    ( 3.9 um)
     S3 - 15-minute water vapor ( 6.8 um)
     S4 - 15-minute thermal IR  (10.7 um)
     S5 - 15-minute long IR     (12.0 um)

anum - default AREA number (default file name that follows AREAnnnn convention).
     This is a bit arbitrary, but it can be useful to control the number
     of images one wants to keep on disk when using the McIDAS routing
     table to control the number of images on disk.  Note that this facility
     is not used by many anymore, instead LDM users create output names
     themselves (pqact.conf actions) that do not follow the AREAnnnn naming
     convention).

     The important thing when assigning 'anum' is to make sure that the
     number does not conflict with those already in use.  Here is what
     I suggest:

     pd   description           wavelength  anum   band
     SV - full disk visible     (0.65 um)   1301   1
     SS - full disk short IR    ( 3.9 um)   1311   2
     SW - full disk water vapor ( 6.8 um)   1321   3
     SI - full disk thermal IR  (10.7 um)   1331   4
     SL - full disk long IR     (12.0 um)   1341   5

     S1 - 15-minute visible     (0.65 um)   1351   1
     S2 - 15-minute short IR    ( 3.9 um)   1361   2
     S3 - 15-minute water vapor ( 6.8 um)   1371   3
     SI - full disk thermal IR  (10.7 um)   1381   4
     S5 - 15-minute long IR     (12.0 um)   1391   5

> any other suggestion about this coding ?

> btw, how I should identify the full disk from the South-America chopping.

Full disk "chopping"?  I am not sure what you mean.  The example product codes
(pd) above will identify which images are full disk and which are the South
American sectors.

> P.S. Today I can put the imagery using other standard for the names.

Very good.

In a follow-up email I will send you the relevant portions of the scripts I
use to create the Unidata-Wisconsin (IDD feedtype UNIWISC) images.

Cheers,

Tom
