<div>Dear users:</div>
<div> </div>
<div>
<div>I have a doubt which someone could solve it:</div>
<div> </div>
<div>I have two data type from:</div>
<div>For one hand I have 16 levels of model levels (45,46,...60) wiht variables u-wind, v-wind, temperature, humedity relative and the surface level with variables: geopotential and log of surface pressure. </div>
<div>For other hand I have 10 levels of pressure levels ( 1000, 975, 950, ....775) with variables u-wind, v-wind and geopotential.</div>
<div> </div>
<div>They are grib files and, with <a href="http://gribctl2.pl">gribctl2.pl</a>, gribmap and grads, I can extract all data in ASCII format but, the question is the following:</div>
<div> </div>
<div>Is it possible to interpolate the data in height and obtain those variables in the heigth that I want. I mean, Is it possible to obtain, from the model levels or pressure levels, heigth levels with GRADS or other program? </div>
<div> </div>
<div> </div>
<div>Thank you very much at all</div>
<div> </div>
<div>Kind regards:</div>
<div> </div>
