<div dir="ltr">Hi:
<div> </div>
<div>Please also respond to the list. Someone on the list might be able to help you faster than I can. Also, members of the list can learn useful information from this exchange.</div>
<div> </div>
<div>It would be helpful if you would verify where the script fails, whether it is the one you are using or a called routine.</div>
<div> </div>
<div>Lastly, the script is telling you that your variable is missing information about what it is. You need to name it, as shown in the NCL help pages.</div>
<div> </div>
<div>But, before you do that, try reading your 4d array into a 2d array and see if you get the same error using the 2d array.</div>

Subject: Re: [ncl-talk] Loop Over Latitude and Level Arrays<br>
<div dir="ltr">Hi:
<div> </div>
<div>When you pass the variable to the kf_filter, you can loop over both over latitude and level, as you pass the 4D variable directly into the routine.</div>
<div> </div>
<div>I am not sure if there is a faster way,</div>
