  Estimates of the number and potential energy of molecules, aerosols, cloud
droplets, insects, birds, planes and satellites in the atmosphere yield a
distribution which is for potential energies below 10^2 kBT described by the
Boltzmann distribution, but for the range from 10^2 kBT to 10^33 kBT by a power
law with an exponent of approximately -1. An explanation for this surprising
behavior is not found.
