<DIV>I am calculating precipitable water by integrating spefific humidity of entire layers</DIV>
<DIV>Below is the script for calculating precipitable water of summer (6,7,8,9) during 1979-2010. Its unit should be mm?<BR> 'reinit'<BR>'sdfopen shum.mon.mean.nc'<BR>'sdfopen pres.mon.mean.nc'<BR>'set z 1 8'<BR>'define w=vint(pres.2(z=1),shum.1,300)/1000'<BR>'set z 1'<BR>'define w6=ave(w,t=378,t=756,12)'<BR>'define w7=ave(w,t=379,t=756,12)'<BR>'define w8=ave(w,t=380,t=756,12)'<BR>'define w9=ave(w,t=381,t=756,12)'<BR>'define sw=(w6+w7+w8+w9)'<BR>'define ww=aave(sw,lon=100,lon=120,lat=25,lat=35)'<BR>'d ww'</DIV>
