[gradsusr] Strange WGRIB2 output behaviour

Mon Feb 19 17:16:28 EST 2024

Hi guys, I hope all is well - I am using WGRIB2 v3.1.2 to extract data to a
spreadsheet format using the -spread as follows and I seem to be getting
incorrect output data - the starting/finishing lat/lon is incorrect which
messes up the entire grid. The data is GRIB2 data from the Australian Bureau
of Meteorology. 

wgrib2 -d 2 -grid IDZ71000_AUS_T_SFC.grb -one_line -npts -set_ext_name 1
-end_FT -ext_name -lev -spread - | more

When I do a wc -l on the output for the number of lines, I only see 300770
points, not the 531405 as reported in the header information.  When I run
the exact same command on a GFS file, it seems to work fine and shows the
correct lat/lon grid:
