Method Details

createFromDewPoint

public static Data createFromDewPoint(Data pressure,
 Data temperature,
 Data dewPoint)
                               throws TypeException,
UnimplementedException,
VisADException,
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:

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.
