<div dir="ltr">Pablo,<div><br></div><div>as Jeff said, your data seems not to be in pressure levels, but in another kind of vertical levels (maybe in km with 1 km of vertical spacement).</div><div><br></div><div>However, if you are completely sure that your data is in pressure leves, you shoud discover what are these levels. For example:</div><div>z 1 correspond to 1000 hPa</div><div>z 2 correspond to 950 hPa</div><div>and so on... </div><div>After that, you have to write these pressure levels explicitly in the control file (ZDEF 29 LEV 1000 950 850 800 750 700 ...).</div><div>Note that if the data is not in pressure levels, the above ZDEF entry will produce a wrong level specification. So, after all, check what kind of vertical level is your data (How have you got the data?) </div><div><br></div><div>Regards,</div><div><br></div><div>Ricardo</div><div><br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><br style="color:rgb(0,0,0);font-family:"times new roman","new york",times,serif;font-size:16px"><span style="color:rgb(0,0,0);font-family:"times new roman","new york",times,serif;font-size:16px">-- </span><br style="color:rgb(0,0,0);font-family:"times new roman","new york",times,serif;font-size:16px"><div style="color:rgb(0,0,0);font-family:"times new roman","new york",times,serif;font-size:16px"><span name="x"></span>Prof. Ricardo Hallak<br>Laboratório de Meteorologia de Mesoescala - LMM<br>Departamento de Ciências Atmosféricas<br>Instituto de Astronomia, Geofísica e Ciências Atmosféricas<br>Universidade de São Paulo<br><br>Phone: +55(11)3091-4698</div></div></div></div>
