<p>Hi all, </p>
<p><br>
</p>
<p>I am trying to access the JRA-55 reanalysis. It seems that there is no model resolution data at pressure levels so I am trying to interpolate them. It seems that the model level's pressure can be calculated using the
<span>pres_hybrid_jra55 function in NCL. But how do I go from there to value at my desired pressure levels (850 mb, 700 mb, 250 mb)?
