<div dir="ltr">Hi Jacob,<div><br></div><div>While NCL uses 0-based indexing, the wrf_user_ll_to_ij routine actually returns the 1-based index from the Fortran routine that gets called under the hood. So, if you were working with NCL, you would need to subtract 1 from the result returned. In your case, you are using Matlab, which is a 1-based indexing system, so you should use the same values that are returned from wrf_user_ll_to_ij. </div><div><br></div><div>Hope this helps,</div><div><br></div><div>Bill</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Aug 2, 2016 at 8:58 AM, Jacob Alberto Garcia <span dir="ltr"><<a href="mailto:jacob_garcia@dlsu.edu.ph" target="_blank">jacob_garcia@dlsu.edu.ph</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><p dir="ltr">Since matlab indexing starts at 1. </p><div class="HOEnZb"><div class="h5">

<p dir="ltr">If i were given 28 29 as the ij output from the wrf ll to if function would that mean that when i extract a variable in that cell index i would have to make it 29 30 in matlab?</p>
<p dir="ltr">Thank you</p>
