public final class SaturationVirtualPotentialTemperature
extends AirTemperature

Provides support for the quantity of atmospheric saturation virtual potential temperature. The equation for virtual potential temperature uses potential temperature in place of in-situ temperature in the equation for virtual temperature. Saturation virtual potential temperature uses the saturation mixing ratio in the computation of virtual temperature.

Creates a saturation virtual potential temperature data object from data objects of in situ air temperature, and water vapor mixing-ratio.

Parameters:

pressure - The air pressure data object.

temperature - The in situ air temperature data object.

Returns:

The virtual air temperature corresponding to the arguments. The type of the returned object will be that of the arguments after standard promotion.

Throws:

TypeException - At least one argument has the wrong type.

UnimplementedException - Necessary operation not yet implemented.

VisADException - Couldn't create necessary VisAD object.

RemoteException - Java RMI failure.
