                                            java.rmi.RemoteException

Creates a virtual potential temperature data object from data objects of air pressure, in situ air temperature, and dew point.

Parameters:

pressure - The air pressure data object.

temperature - The in situ air temperature data object.

dewPoint - The dew point 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:

visad.TypeException - At least one argument has the wrong type.

visad.UnimplementedException - Necessary operation not yet implemented.

visad.VisADException - Couldn't create necessary VisAD object.

java.rmi.RemoteException - Java RMI failure.

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:

visad.TypeException - At least one argument has the wrong type.

visad.UnimplementedException - Necessary operation not yet implemented.

visad.VisADException - Couldn't create necessary VisAD object.

java.rmi.RemoteException - Java RMI failure.
