At the end of this teaching unit, the student will be able to :
1.   describe the main processes defining the trace gas composition of the upper atmosphere ;
2.    understand the basic principles of atmospheric remote sensing: geometry, spectral domains and observation methods ;
3.    understand the inverse problems related to ground-based and space-borne observations ;
4.   assess the error budgets for several remote sensing modes and identify their intrinsic limitations ;
5.   understand the design principles of a space remote sensor and its operational use.
