GEMPAK Support for GOES ABI NetCDF
GOES16 and GOES17 ABI products are distributed in NetCDF4 formatted files, and GEMPAK as of release 7.5.1 can now read and display these products in their native formats (it is no longer needed to convert netCDF to McIDAS area format to display in GEMPAK).
For Full Disk and CONUS sectors, GOES16 and GOES17 ABI products are sent across the Satellite Broadcast Network as tiles, each contributing to a "mosaic" of a full sector scan. The Unidata Program Center has provided an alternate data feed in which all tiles are "stitched" together (thanks to the program ldm-alchemy).
ldmd.conf
To request these stitched images, add the following request line to your ldmd.conf:
REQUEST NIMAGE 'GOES' idd.unidata.ucar.edu pqact.conf
The following pattern action
NIMAGE ^/data/ldm/pub/native/satellite/GOES/(.*)/([^/]*)/([^/]*)/([0-9]{8})/GOES(16|17)_([^/]*)_([0-9]{8})_([0-9]{4})(..)_([^/]*).nc4 FILE -close data/gempak/images/sat/1/2/3/3_7_8 will create files such as :
$SAT/GOES16/CONUS/Channel02/Channel02_20181227_1812 $SAT/GOES16/CONUS/Channel08/Channel08_20181227_1812 $SAT/GOES16/CONUS/Channel13/Channel13_20181227_1942 for each of the 16 ABI channels (here the environmental variable SAT = /data/ldm/gempak/images/sat/) and each available sector (e.g. CONUS above).
NMAP2 Display
The above pqact.conf entry will write images to directories in $SAT, which are then selectable in NMAP2 > New Data Source > Image
GOES16 Full Disk
GOES16 CONUS
GOES16 PRREGI
GOES16 Mesoscale-1
GOES16 Mesoscale-2
GOES17 Full Disk*
- as seen above there is still a map projection error for GOES17 Full Disk images.
GOES17 CONUS
GOES17 AKREGI
GOES17 HIREGI
GOES17 Mesoscale-1
GOES17 Mesoscale-2
