Numerical Solution of Functional Equations by Means of Laplace Transform—III: The Diffusion Equation

One of the fundamental equations of chemistry and biology is the heat or diffusion equation. A new method for its numerical integration is presented, which hinges on the numerical inversion of Laplace transforms. One advantage over the usual finite...

Radiative Equilibrium of the Mesosphere.

Results of joint photochemical-radiative equilibrium calculations for the mesosphere and upper stratosphere. Major assumptions are that only oxygen allotropes participate in the chemistry and that the radiative balance is between absorption of solar ...

The Response Time of the Lower Ionosphere to a Pulse of Ionization.

A discussion of the recovery time of ionization in the low ionosphere (60- to 100-km altitude). It is known that both the local air chemistry and the level of ambient ionization affect the lifetime of free electrons in the ionosphere. The model for t...
