If you're running WRF, there's either the WRF Post Processor (<a href="http://www.dtcenter.org/wrf-nmm/users/downloads/index.php">http://www.dtcenter.org/wrf-nmm/users/downloads/index.php</a>) or ARWPost (<a href="http://www.mmm.ucar.edu/wrf/users/download/get_sources.html">http://www.mmm.ucar.edu/wrf/users/download/get_sources.html</a>). Each one can take model level data and interpret it to height levels, pressure levels, or just keep it on model levels but add diagnostic variables. You do need to register an email address to download them.<br>

<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" target="_blank">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>
