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

Dear ferret users,
I have a netcdf file in which potential temperature is one of the
parameters.
Now I need tom convert this potential temperature to regular
temperature.
How it could be done, Please anyone help me.
Thanks and regards
