P,<br>You can use the hydrostatic equation and a form of the hypsometric equation to determine height as long as you're given two pressure values and the mean temperature in a layer bounded by the height you desire. The equation is:<br>
<br>DZ = -(RT/g)*ln*(p2/p1), where<br><br>R is the dry air gas constant<br>T is the mean temperature in the layer bounded by pressure levels p2<p1, and<br>DZ is the thickness of the layer (i.e., DZ = z2 - z1 for z2>z1). I would recommend using z1 = 0 as the bottom of your layer to make computations feasible.<br>
<br>Hope this helps.<br><br>Jeff Duda<br><br><div class="gmail_quote">On Tue, May 24, 2011 at 4:58 AM, bala vasanthakumar <span dir="ltr"><<a href="mailto:bala_vasanthakumar@rediffmail.com">bala_vasanthakumar@rediffmail.com</a>></span> wrote:<br>
