Hi Tony,

>Is the half-hourly imagery for the IR(10.7) and VIS(0.65) coming in now?

Yes.  All imager channels for GOES-East and GOES-West are now being
sent twice per hour.

>I don't see it even though I changed my ldmd.conf to look like:
>
>request        UNIWISC "Q. (C[^GH]|U[^78DE])" rainbow.al.noaa.gov

This request line keeps you ingesting what you got _before_ the
datastream change.  If you want all images all of the time, you
should change your request line to:

request UNIWISC ".*"    rainbow.al.noaa.gov

>I'm still getting only hourly images.  As I understand it, I don't need to
>modify the decoders or pqact.conf?

There is not need to modify/update the decoders.  There is a need
to modify pqact.conf depending on how you decode the data.  If
you use the GEMPAK hierarchical method of image storage and you
have not updated pqact.conf, you will be missing decode actions for
the short IR (3.9 um) and long IR (13.3 um for GOES-East and 12.0 um
for GOES-West) images.

Here are the pqact.conf actions that you should either add or modify:

# Short IR (3.9 um)
MCIDAS  ^pnga2area Q. (U[^ACXY13]) (.*) (.*)_IMG (3.9)um (.*) (........) (....)
        PIPE    -close
        pnga2area -vl logs/ldm-mcidas.log
        -a etc/SATANNOT
        -b etc/SATBAND
        data/gempak/images/sat/\3/\5/\4/\4_\6_\7

# WV (6.[58] um)
MCIDAS  ^pnga2area Q. (U[^ACXY13]) (.*) (.*)_IMG (6..)um (.*) (........) (....)
        PIPE    -close
        pnga2area -vl logs/ldm-mcidas.log
        -a etc/SATANNOT
        -b etc/SATBAND
        data/gempak/images/sat/\3/\5/WV/WV_\6_\7

# Long IR (GOES-East: 13.3 um; GOES-West: 12.0 um)
MCIDAS  ^pnga2area Q. (U[8E]) (.*) (.*)_IMG (.*)um (.*) (........) (....)
        PIPE    -close
        pnga2area -vl logs/ldm-mcidas.log
        -a etc/SATANNOT
        -b etc/SATBAND
        data/gempak/images/sat/\3/\5/\4/\4_\6_\7


NOTE:  You may need to alter the directory in which you are decoding
your images to match your existing setup!  Follow the existing pnga2area
decode actions in your pqact.conf file and modify the above to fit with
your installation.

>Thanks,

No worries.

Tom,

It seems that the problem was not in my ldmd.conf request but rather in
my pqact.conf.  I had

MCIDAS ^pnga2area Q1 .... when it should have been Q.

So I guess I was receiving the half-hourly images but not doing
anything with them.

Thanks and hope things are well.

Tony
