Can any one help me converting the CHE.mon.ctl file out put data to pressure level data.

 

I sucessfully simulated the RegCM CHE model but failed to get the correct results of Aerosols from the parameter aext8.

 

I used AD=sum(aext8,z=1,z=18)

 

Still I didnt get the result.

 

Please help me very soon

Thanks in advance.

 

With regards
