Re: [ferret_users] Temperature calculation from potential temperature.

[Russ Fiedler <russell.fiedler@xxxxxxxx>]

Hi,

You need the function THETA_FO with the reversed pressure arguments.

http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/variables-xpressions/XPRESSIONS#_VPID_113


let temp_insitu = theta_fo( salt, temp_pot , p_ref , p )

where p_ref is the reference pressure for potential temperature (usually 
zero).

i.e

let temp_insitu = theta_fo(salt, temp_pot , 0. , p )



Cheers,
Russ
