The following equation describes the observed decrease in density with increasing altitude in the lowest 100km of the atmosphere: p(z) = p0 exp(-z/h) where p(z) is the air density at altitude z, p0 is the density at sea level, and h is the scale height. The density of air at sea level is 1.25 kg m^-3. Calculate the scale height H that is consistent with the observed sea level pressure of 1013 mb. (Hint: Integrate the above equation from sea level to infinity to find the atmospheric mass per unit area).
