<p class=MsoNormal>Hallo people,<o:p></o:p></p>

<div>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

</div>

<div>

<p class=MsoNormal>I'm working currently with WRF and doing the postprocessing
with ARWpost. I'd like to convert the output&nbsp;from ARWpost into Grib
format. I've tried to use GrADS with 'lats4d' but I have found something wrog.
In order to check the transformation of the files I compare surface varibles,
like T2,&nbsp;available both before the transformation (WRF in NetCDF format)
and&nbsp;after the transformation (the GRIB file). I'm quite surprised because
the differences change considerably: for the same grid many times are the
differences of the order of 0.01°C but some times are they close to 1.0°. I
don't know if the problem boils down to some interpolations problem.<o:p></o:p></p>

<div>

<p class=MsoNormal>My question ist: has anybody experienced the same problem?
is a such difference, in your opinion, acceptable?<o:p></o:p></p>

<p class=MsoNormal>I'd appreciate your help.<o:p></o:p></p>
