I got a nice script from the<a href="http://www.iges.org/grads/gadoc/library.html"> script library</a> that doesn't appear to be there anymore, but I've attached it to this email.� It will plot an arbitrary cross section using the collect command.� As far as obtaining water vapor mass, really the only way is to use the density of dry air to get water vapor density, or q*rho, where q is water vapor mixing ratio and rho is dry-air density.� <br>

<div>You should easily be able to set the dimensions such that the display
output yeilds a cross section, at least along some latitude or longitude line,
but I know there are ways to do it along any line of choice. Just allow only
the z and some horizontal dimension to vary, with all other diimensions fixed.
Are you looking for vertically integrated water mass, or just wishing to plot
isopleths of mixing ratio?</div>
