Hi all,
<div class=""><br class="">
</div>
<div class="">I am using a coupled configuration of the MITgcm with a cube-sphere grid (C24), and I am trying to calculate the curl of the surface wind-stress in order to understand Ekman layer dynamics in the model ocean. </div>
<div class=""><br class="">
</div>
<div class="">I found the script calc_vort_cs.m in the MATLAB MITgcm utils and provide it with surface wind stress fields, however I’m unsure how to interpret the outputs, which come in ‘compressed form’ (nc*6*nc+2, 1) or ‘face-splitted form’ (nc+1, nc+1, 1, 6). I’d
like to be able to get them into a familiar form of (6*nc, nc, 1), which I can then diagnose with other utils. </div>
<div class=""><br class="">
</div>
<div class="">Is anyone familiar with converting between these forms for cube-sphere grid data?</div>
<div class=""><br class="">
</div>
<div class="">Thanks and all the best,</div>
<div class=""><br class="">
</div>
<div class="">Peter</div>
