Arguments
label	type	description
theta	variable or constant	Potential Temperature
S	variable or constant	Salinity
P	variable or constant	Pressure
Returns
alpha/beta	variable or constant	Ratio of alpha to beta

Description

abrat uses potential temperature, salinity, and pressure values in the ocean to calculate the ratio of alpha (the thermal expansion coefficient) to beta (the saline contraction coefficient).
