Re: theta_fo documentation mismatch
Keith,
Thanks for bringing this to our attention. The arguments to THETA_FO are
correct in the Users Guide.
THETA_FO( salt, temp, Z, Z_reference )
Where Z should refer to Pressure and Z_reference to reference temperature
The code lists these units, and a checkvalue
C UNITS:
C PRESSURE PO DECIBARS
C TEMPERATURE TO DEG CELSIUS (IPTS-68)
C SALINITY S (PSS-78)
C REFERENCE PRS PR DECIBARS
C POTENTIAL TEMP THETA DEG CELSIUS
C
C CHECKVALUE: THETA=36.89073 DEG C: S=40(PSS-78), TO=40 DEG C,
C
And indeed when calling the function from Ferret:
yes? list theta_fo(40, 40, 10000, 0)
THETA_FO(40, 40, 10000, 0)
36.89
We'll get this corrected in the Ferret code which documents the function!
