Absorption spectra of atmospheric gases in the IR, visible ...

2 Dependencies: S depends on T; f( – 0, ) depends on the line halfwidth (p, T), which depends on pressure and temperature. Path length (or path) is defined as the amount of an absorber along the path. Since the amount of the absorbing gas can be expressed in different ways (see Lecture 5) the different measures of path length are used.

1. Composition of air. - gatech.edu

The composition of the atmosphere is a key factor determining its properties. The Earth’s atmosphere serves us in several capacities: ... chemical compound, which is a collection of atoms, is obtained by summing the masses of atoms. NOTE: the terms molar mass and molecular weight mean exactly the same
