2: The upper atmosphere
8 January 2018
We looked at gas kinetic particles. We introduced the
particle density and developed the Maxwell-Boltzmann speed
distribution. We derived the peak velocity, the mean velocity
and the rms velocity.
We covered the collision frequency, mean free path. We
have now successfully derived expressions for the gas kinetic
parameters, particle density, random velocity, collision
frequency and mean free path.
We turned to macroscopic properties of gas. We covered
particle flux, momentum flux, pressure and temperature.

We covered the ideal gas equation, the specific heat
capacity and the adiabatic changes of state. We have now
successfully derived the macroscopic parameters, pressure
temperature and specific heat capacity.
We covered the aerostatic equation. and the barometric
We looked at the homework
assignment and then continued with the course. We covered the barometric law. We
looked at an example of the relative decrease of the number
density of gas particles in the atmosphere of Mars. The we
summarized the atmospheric divisions.

We looked at another atmospheric division, composition,
and distinguished between homosphere and heterosphere.
with other atmospheric divisions, vertical transport and
the escape velocity, introduced frictional force and applied
it to satellite atmospheric drag.
We looked at a block diagram of a time-varying
atmospheric model and learned about the specific parameters
that are needed for such a model.
We returned to the escape velocity and computed the
escape time for different constituents of the Earth atmosphere as
well as the constituents of the atmospheres of other planets.
