Hi Nick,
From https://www.unidata.ucar.edu/software/gempak/man/prog/nex2gini.html
NEX2GINI uses a suplemental table $GEMTBL/unidata/nex2gini.tbl to specify
configurations for product identifiers so that the generated images
are correctly identified for enhancement tables in $GEMTBL/sat/imgtyp.tbl.
In the file $GEMTBL/unidata/nex2gini.tb you will see an entry for N1P:
N1P 30 4
inches,0,9,-9999,-9999;10,100,0,0.5;101,200,0.5,5;201,255,5,12 TICZ99
CHIZ
as well as a descriptor of the format of this entry in the header (which
coincidentally describes the N1P entry):
!Prod band ncal units,Calval_1;....;calval_n Prod_header
!
! Prod = Product identified 3-alpha-numeric
! band = unique "satellite id"
! ncal = number of calibration units
! units = calibration value, such as "1 dBZ" for reflectivity
! * then followed by calibration ranges. for N1P:
! - 3 calibration ranges:
! * 0-4 inches = 10-110
! * 4-12 inches = 110-220
! * 12-24 inches = 210-255
You can customize this entry and then run the nex2gini or nex2img programs to
see the changed results.
> My second question is regarding compositing DAA. I see that there's
> already a line in the nex2gini and imgtyp tables, but if I try to
> composite it, I get an "expecting bzip2 compression, not found -5"

There is an entry for DAA,
DAA 21 4
inches,0,9,-9999,-9999;10,100,0,0.5;101,200,0.5,5;201,255,5,12 TICZ99
CHIZ
but I have confirmed that it is not working at the moment. I'll take a look in
the coming days and see if I can get a fix into GEMPAK for it.
