w3fa04()

subroutine w3fa04	(		height,
			press,
			temp,
			theta
	)

Computes the standard pressure, temperature, and poten- tial temperature given the height in meters (<32 km).

For the pressure and temperature the results duplicate the values in the U.S. standard atmosphere (1962), which is the icao standard atmosphere to 54.7487 mb (20 km) and the proposed extension to 8.68 mb (32 km). For potential temperature a value of 2/7 is used for rd/cp.

Parameters

[in]	HEIGHT	Height in meters.
[out]	PRESS	Standard pressure in millibars.
[out]	TEMP	Temperature in degrees kelvin.
[out]	THETA	Potential temperature in degrees kelvin.

Note

Not valid for heights greater than 32 km. declare all parameters as type real*4.
