Grads and ECMWF data error

[Wesley Ebisuzaki]

Jeremy,

       Grib2ctl assumes that all the fields use the same grid.  For your
file, records 1 and 2
are on a 144x29 grid (255).  The  remaining records are on a 144x73 grid
(2).    To extract the
global grid, you can use wgrib

wgrib -s nrecmgrb25.t00z -PDS | sed
's/PDS=............\(..\)[0-9a-f]*:*/grid=\1h:/' | grep "grid=02h" |
wgrib -i nrecmgrb25.t00z -grib -o new.grib

Yes, it does look the results of a monkey banging on a keyboard.
However, you should be able to plot "new.grib".
