Hi all,
</p>
<p>
Regarding the model output u and v components of wind, are they defined according to true east/north or according to the model domain x/y directions?
</p>
<p>
If the latter, I assume a correction is needed to true lon/lat direction when comparing to observed u/v measurements or observed wind direction, right?
</p>
<p>
Kind regards,
</p>

The U and V components are defined wrt to the computational grid. You can de-rotate them using the
<span class="caps">
CDO
</span>
tool “rotuvb”. If de-rotating “manually” by the de-rotation formula, be careful that there may still be an error in the
<span class="caps">
CCLM
</span>
documentation. See this discussion https://redc.clm-community.eu/boards/10/topics/518

Good luck!

Okay, I’ll try that. Thanks for the quick reply Edmund!
