Python: How to get the adjusted-to-sea level barometric pressure from actual pressure, temperature and height above the sea level

	# Actual atmospheric pressure in hPa
	aap = 990
	# Actual temperature in Celsius
	atc = 10
	# Height above sea level
	hasl = 500

	# Adjusted-to-the-sea barometric pressure
	a2ts = aap + ((aap * 9.80665 * hasl)/(287 * (273 + atc + (hasl/400))))
