Neon makes up 0.0018% of the air in the atmosphere.
Assume atmospheric pressure (temperature) is 1.0 atm (25°C) at sea level,
and 0.0030 atm (－10°C) at 40 km (high in the stratosphere).
Calculate the partial pressure of Ne (in atm) at each altitude.
Convert these partial pressures to units of ppmv.
Compare your values in (a) and (b).
What is the limitation of reporting relative concentrations in ppmv as compared to partial pressures?
