<body class='hmmessage'><div dir='ltr'><pre>Hello grads users, this is my second request, hope you could help me.<br><br><br><br> i'm fairly new using grads. I have a netcdf file that contains monthly mean data of zonal wind from 1871 to 2010, and i need to obtain individual mean values for each month for a given region (volume).
i was using the amean function, but a can only get a value of an area, and when i modify the lev parameter i get an error message, like this:
set lev 1000 700
a=amean(uwnd, lat=0, lat=25, lon=260, lon=300)
then i tried nesting various mean functions like this:
a=mean(mean(mean(uwnd,lat=0,lat=25),lon=260,lon=300),lev=1000,lev=700)
and i get a result, but i don't know if this is correct. Is this the right way to do it, or are there other ways?
Hope you can help me. Thanks in advance.
Alejandro.</pre><br><br><em><font color="#ff0000" face="Garamond, Times, Serif " size="4"></font></em> </div></body>
