[gradsusr] reading ds094.0 data with template

[Antoine Molin]

Hi,

 

Using  ds094.0  daily files  like : < cdas1.20121001.pgrbh.grb2 >, each data
at time 00h is -9.99E+08.

It is not a problem if i want to read one day file : if the first data at
00h is false, it can be obtained as last data of the day before.

But if i want to read one month with daily files (see enclosed files) using
template, all my data at t=00h are false ; See the U_wind data at lat 45,
lon 5, t=1 to 744 in grads_IEE.txt.

 

i think that perhaps my .ctl is not good ? I tried undef= -9.99 e+08 and
undef=9.999E+20, but it doesn't change anything.

 

In fact we have 2 data for time 00h in these files, and the false one is
read.

 

So I think i am not using < template > as it should ! Is there a change to
do in my .ctl ?? 

 

Thanks, and best regards.
