Dave,

>Below is what I currently have to pick up satellite images.  What
>do I need to do to get the new format images?

In the recommendations below I am assuming that the images end up being
named as follows on your system:

Product          Name
----------------+-------------------------------
GOES-West VIS    YYMMDDHH_svw.mca
GOES-West IR     YYMMDDHH_siw.mca
GOES-West H2O    YYMMDDHH_sww.mca
GOES-East VIS    YYMMDDHH_sve.mca
GOES-East IR     YYMMDDHH_sie.mca
GOES-East H2O    YYMMDDHH_swe.mca

where the date/time portions of the file names are supplied by the LDM
from your machine's realtime clock.  I am also assuming that they are
being put into the /home.heron/ldm/mcidas directory.  Finally, I assume
that you have put the SATANNOT and SATBAND files from the ldm-mcidas
distribution into the /home.heron/ldm/etc directory.

I would replace the use of the real clock date/time with the date/time
from the image itself.  Given this, the new entries would be:

The 'Q1' specification will select products tagged as representing images
scanned in the first 15 minutes of the hour:

Specifier   Image scan time
-----------+---------------
   Q.             any
   Q0         H=01 - H+60
   Q1         H+01 - H+15
   Q2         H+16 - H+30
   Q3         H+31 - H+45
   Q4         H+46 - H+60

The CIMSS images are tagged 'Q0' since they are not scanned images; they
are products.  The images currently in the datastream will be tagged 'Q1'
mostly because they are scanned in the first quarter of the hour (the
Manually Digitized Radar product is an exception).

A mask of 'Q.' will match any 'Qx' specifier, so you may want to modify
the above to use 'Q.' instead of 'Q1'.

The '%%' (doubled percent) insures that the strftime date/time specifiers
are interpreted by 'pnga2area' instead of by the LDM.

Please let me know if any of the above is not clear.
