[ncl-talk] zonal_mpsi

[Chathurika]

Dear all,




I want to calculate zonal mean meridional stream function using "zonal_mpsi" function. I have a dataset which is meridional velocity (time, plev, lat, lon). 




I am little bit confused about what is 'ps' (surface pressures).  Same dimensions as velocity but the level and unit must be pa. Could you please tell me what should I use for the ps?




I am sorry about the silly question but please help me.




Many many thanks 

and best regards,

Chathu
