Hi Gerry, re: > Thanks. What pattern(s) am I looking for on the SATELLITE feed? The pattern you use will depend on the images you want. The LDM/IDD Product IDs for the GOES-16 products are the fully qualified pathnames of the files as written by CSPP GEO. Here are some examples: Full Disk /data/cspp-geo/GRB-R/OR_ABI-L1b-RadF-M3C15_G16_s20181071500428_e20181071511201_c20181071511267.nc CONUS /data/cspp-geo/GRB-R/OR_ABI-L1b-RadC-M3C04_G16_s20181071512236_e20181071515009_c20181071515050.nc Mesoscale-1 /data/cspp-geo/GRB-R/OR_ABI-L1b-RadM1-M3C14_G16_s20181071509315_e20181071509372_c20181071509412.nc Mesoscale-2 /data/cspp-geo/GRB-R/OR_ABI-L1b-RadM2-M3C03_G16_s20181071510015_e20181071510072_c20181071510114.nc The operative things to know are: - the coverage is defined by the 1 or 2 characters immediately after Rad RadC - CONUS RadF - Full Disk RadM1 - Mesoscale-1 RadM2 - Mesoscale-2 - the wavelength channel is represented as the 3 character sequence immediately after the scanning mode M3 - scanning mode 3 C03 - Channel 3 C14 - Channel 4 Given this, if you want all channels of the Full disk coverage only, then your LDM REQUEST line would like more or less like: REQUEST DIFAX "RadF" idd.unidata.ucar.edu If you only wanted channels 2, 9 and 13 of the Full Disk coverage, the REQUEST would look something like: REQUEST DIFAX "RadF-M.C(02|09|13)" idd.unidata.ucar.edu etc. NB: The feed is named SATELLITE for LDM versions 6.13.7 and newer (even though v6.13.7 has not been officially released yet) and DIFAX in older versions. The SATELLITE (aka DIFAX) feed is available from the two top level IDD relays that we operate here in UCAR: idd.unidata.ucar.edu iddb.unidata.ucar.edu Comments: - it is our experience that sites that REQUEST GRB ABI imagery also eventually REQUEST GLM products Here is a Product ID for the GLM product: /data/cspp-geo/GRB-R/OR_GLM-L2-LCFA_G16_s20181071526400_e20181071527000_c20181071527020.nc - you can easily get a listing of the Product IDs by running the LDM utility 'notifyme' Example: <as 'ldm'> notifyme -vl- -f DIFAX -h idd.unidata.ucar.edu -o 600 Cheers, Tom -- **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
