(apologies if you are both on the GEMBUD and AWIPS email lists as this will be a duplicate…) Greetings. As of 06 28 2023 12z it seems the ECMWF’s freely available WMO Essential grib2 data has changed (here). It is no longer fully processable by dcgrib2
or AWIPS EDEX We did not see any change notice on ECMWF web site or Google and were wondering if anyone else is experiencing the following (attached is a one-field <500 mb HGT> grib2 file), and if you did would you happen to know the cause and any workarounds? wgrib2 -v -V test.grb2 shows what looks like a viable grib2 file 1:0:vt=2023062803:500 mb:3 hour fcst:HGT Geopotential Height [gpm]: ndata=405900:undef=0:mean=5562.91:min=4689.51:max=5955.01 grid_template=0:winds(N/S): lat-lon grid:(900 x 451) units 1e-06 input WE:NS output WE:SN res 48 lat 90.000000 to -90.000000 by 0.400000 lon 180.000000 to 179.600000 by 0.400000 #points=405900 basic_ang=0 sub_angle=1000000 units=0.000001 unscaled lat=90000000 to -90000000 lon=180000000 to 179600000 As additional info a wgrib2 -v –V on a grib2 file previous to June 28 shows the same thing as above. Submitting to EDEX shows the following error (at the end in bold with preceding traceback messages) ERROR 2023-06-28 19:02:42,848 4308 [Ingest.GribDecode-6] grib: EDEX - Error processing file [/awips2/data_store/manual/grib/20230628/19/test.grb2]: Traceback (most recent call last): File "/awips2/edex/lib/plugins/com.raytheon.edex.plugin.grib.jar/GribDecoder.py", line 184, in decode gribDictList = grib2.decode(gribFile, self.startPosition, self.messageLength) error: Failed to get grib field.
