Hi Steve,

I can confirm that the GOES-16 data being sent as if it were stillGOES-13 works without any modifications to my GEMPAK setup.


Excellent, that was my intention.

re:

I would second Victor's nomination of EAST-CONUS, and add the compositefeeds NHEM-COMP and SUPER-NATIONAL if possible (not sure how easy it isto stitch together GOES-16 with GOES-15, though).


The Unidata-Wisconsin datastream already has a set of GOES-East/West
composites (one for each GVAR band), but their resolutions are much
less (20 km) than the GINI Super National sector (8 km resolution).
Increasing the size and resolutions of the composites would not be
hard (they could go as high as 4 km which is what the IR channels
on GOES-15 provide).  Have you taken a look at these composites?

re:

Not the highestpriority given it is January, but the tropics sectors PR-NATIONAL andPR-REGIONAL would be nice as well.


OK.  Creation of a Puerto centered sector should not prove to be too
difficult.  The question is if users need/want the same resolutions/
coverages as were provided by the GINI Puerto Rico regional and
national sectors.  FYI: the NWS is sending the equivalent to the
Puerto Rico regional sector as an SCMI image in NOAAPort.  Looks
like they figured that the full disk coverages would provide
all that was needed to replace the Puerto Rico national sector.

re:

I hope to get all of our satellite imagery on our website driven byPython eventually, but the addition of these sectors would be a greatinterim measure.


I believe that there is work to be done on the Python side to support
imagery in AREA format.  This may or may not be important in the
long run.

Cheers,

Tom

Hi all,

It appears someone has figured out G16 and GEMPAK:https://satelliteliaisonblog.com/tag/goes-16/<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsatelliteliaisonblog.com%2Ftag%2Fgoes-16%2F&data=02%7C01%7Csgdecker%40envsci.rutgers.edu%7Cceddb273c4bb4e03716508d55b8c00a5%7Cb92d2b234d35447093ff69aca6632ffe%7C1%7C1%7C636515579265449705&sdata=aZCPZ8UJHh4SzHCvBtwBf6Hlx4%2BXLVabujmsbOLDlEM%3D&reserved=0>

At any rate, I too, would like to see the NIMAGE feed EAST-CONUS withthe previous products offerred by G13. All of my GEMPAK satellitescripts are currently broken.

        Thanks for all of the feedback, all. - same Tom, would be

interested but we understand that this is a big undertaking. Same as Rodrigo — for us, just the ability to produce VIS, IR

        and WV imagery would be fine as we disseminate a few products to
        the general public and for internal instructional purposes.


    This past Monday, January 8, I replaced the GOES-13 image content in

Unidata-Wisconsin (IDD feed type UNIWISC aka MCIDAS) GOES-Eastsectors

    with similar bands from GOES-16.  In order to provide an impact-free

transition, I left the images labeling as being from GOES-13.Since the images are being created by McIDAS remapping (IMGREMP) of GOES-16Full

    Disk imagery into existing GOES-13 sectors, the navigation for the

images is still that for GVAR, not the Fixed Grid projection ofGOES-16.

    GEMPAK, McIDAS, IDV, McIDAS-V and presumably AWIPS users should be
    able to use these images with no changes to their setup (i.e., no
    adjustments
    to GEMPAK tables, etc.).

    I view the remapping of GOES-16 imagery into GVAR sectors as being a
    stop gap measure designed to lessen the impact of GOES-13 being
    turned off.  I want to open a full discussion with LDM/IDD
    consumers of satellite imagery for what the next steps should be:
    e.g., send out select bands from the GOES-16 SCMI imagery that
    is being distributed in NOAAPort; create image sectors that match
    the spatial extents for the GOES-13 imagery that was sent in NOAAPort
    in GINI format, etc.

    Some questions to be answered before we proceed with the creation of
    new image content using GOES-16 data are:

    - does GEMPAK support the Fixed Grid projection used in all GOES-16
       GRB images?

       I _think_ the answer to this is no, Fixed Grid is not supported in
       GEMPAK, but I am not sure.  If it is not, new image sectors can
       be remapped into a projection that GEMPAK supports.

    - which bands would GEMPAK users like to see in the new content?

       Recall that GVAR GOES platforms have 5 imager channels (bands),
       while GOES-R has 16 ABI channels.

    - do GEMPAK users need to be able to extract valid calibrations
       from the imagery (e.g., TEMPerature for IR bands and Albedo/
       reflectance from VISible bands)?

       If yes, this may mean that non-GOES-16 calibration information
       will need to be added to the new image sectors.

    - what LDM/IDD datastream should these image sectors be sent in?

    Comment(s):

    - creation of image sectors that are usable by GEMPAK is not
       a daunting task ** as long as the output format for the
       new sectors is McIDAS AREA **

       Creation of new sectors in GINI format would require new program
       development while creation in AREA format simply requires the
       creation of scripts that run appropriate McIDAS commands.

    Your input is important.  Please let us know what option would be
    best for your operations!

    Cheers,

    Tom

            Hi Tom!

            We are very interested in GOES-16 on Gempak. We have been
            trying to migrate to AWIPS II, but it is not possible yet
            and we use GOES daily on Gempak for maritime forecasts in
            Brazil. We are worried about the coming end of GOES-13
            imagery. It is not necessary all the products and channels,
            but the enough of basic IR, VIS and WV imagery.

            Regards,
            Rodrigo

                 This brings up a good question in my mind: does GEMPAK
            support the
                 Fixed
                 Grid projection that is used for all products
            distributed in the GRB
                 (GOES ReBroadcast)?   If not, McIDAS can remap the
            images into
                 projections supported by GEMPAK, but this would entail
            some loss of
                 information.

                 re:

                     What is AWS?


                 Amazon Web Services - Amazon's cloud.  All GOES-16 data
            has been moved
                 up to AWS since the satellite was turned on.

                 If anyone is not on the ldm-users email list, please be
            aware that we
                 are distributing ALL of the GOES-16 imagery and
            products we are
                 receiving here in UCAR.  The imagery and products are
            under the DIFAX
                 feed type, but this will be renamed to SATELLITE in an
            upcoming
                 LDM release (while keeping DIFAX as a secondary name,
            of course).

                 A much bigger question for the community as a whole is
            if there is
                 a desire for us (Unidata) to distribute GOES-16 imagery
            in a format
                 that is readily usable by GEMPAK (e.g., AREA, NOT
            GINI!)?  If the
                 answer is yes, what sectors are of interest (NB: not
            all bands!!).
                 We have been discussing using McIDAS to turn the
            NOAAPort-delivered
                 SCMI netCDF4 images into McIDAS AREAs and providing
            them in a
                 satellite image based feed type like UNIWISC, NIMAGE,
            or possibly
                 SATELLITE.

                 Cheers,

                 Tom

                     Using mcidas, you can make area files using the
            GOES-16 netcdf
                     files, if you use the data that's on AWS.

                     It is something I will have to tackle here in a few

            assume that with

                     Hi Gembuds,

                     I am successfully ingesting the GOES-16 data but am
            having
                     difficulty displaying it.  I’m assuming I probably
            have to run
                     it through (or perhaps create) some kind of
            decoder.  Has
                     anyone had success that might be able to provide a
            few pointers?
