20000810: Satellite imagery with Garp

Pat,

You probably need to configure the $GARPHOME/config/Garp_defaults
file for your 4 digit YYYY entries - the default configuration
was for the 2 digit years.

Make sure the satT entry you are using is the YYYY entry:
satT   : $(SATDIR)/%(platform)/%(resolution)/%(product)/*_@(YYYYMMDD)_@(HHNN)

The invalid month is probably a complaint about the MM getting set to 00.

If NSAT is viewing the data, then the directory structure sounds correct.

Also, you might want to shorten the sat key list to only the subdirectories you 
have, eg,
shorten:
sat             : "$(G7) $(G8) $(G9) $(G10) $(GINI) $(COMPOSITE) $(GMS) $(MDR) 
$(FLOAT1) $(FLOAT2) $(SPOLE) $(GSOUND)"
to something like:
sat : "$(G8) $(G10) $(FLOAT1) $(FLOAT2) $(SPOLE) $(GSOUND)"

since you don't have Goes-7, GMS, GINI, etc, there is no need to try to look in 
them for data.

Once you are able to directly file your images into the SAT tree structure from 
the LDM with 
pnga2area, you wont have to run nsat_links anymore. You will have to set up 
scour to
remove the old data though.
