[gradsusr] Precip Issue with ECM/MET office data

[CW Weather]

Hello Grads users,

When using ECMWF data and also certain Met Office data the precipitation 
values are undefined. On closer inspection when I inventory the grib as 
shown below, the first line has 0 figure (in bold) at the start where 
there should be a value. No matter what hour I start on it shows a zero 
value. I believe this is preventing the data running. I use curl to 
download the grib and perl to create the ctl file. (example at the 
bottom)

Perl:

@ECHO Please wait, concatenating grb files...
cat *.grb > metoglb_grib.grib2
@ECHO Please wait, creating ctl file...
perl g2ctl.pl -verf metoglb_grib.grib2 > metogl_grib.ctl
@ECHO Please wait, creating idx file...
gribmap -i metoglb_grib.ctl -e
