3. (iniz) Assume the atmosphere is isothermal at 300 K (very tropical). The surface humidity is 70%. Let the vapor be distributed uniformly in the first 1.5 km, and the air is dry above that. For simplicity take the air pressure to be uniform (1000 hPa) in this lowest 1.5 km. (a)) What is the scale height of the atmosphere in this case?

Question
3. (iniz) Assume the atmosphere is isothermal at 300 K (very tropical). The surface
humidity is 70%. Let the vapor be distributed uniformly in the first 1.5 km, and the air is dry
above that. For simplicity take the air pressure to be uniform (1000 hPa) in this lowest 1.5 km.
(a)) What is the scale height of the atmosphere in this case?
(b) How much water (in vapor form) lies above a given square meter of surface (kg m-²)? Use the
air density in the 1.5 km layer = 1.2 kg/m³.
