Most satellite measurements of atmosphere related quantities and parameters come from passive instrumentation, that provides huge amounts of data for global scale atmospheric analysis with quite limited spatial resolution. When higher resolution is desired, ground based systems are opportunely exploited. The increasing use of satellites pushes the research towards the realization of systems, based both on spaceborne and ground instrumentation, designed to exploit attenuation measurements at the infrared. The distribution of atmospheric molecular components can be retrieved from such measurements through ad-hoc tomographic processing. In this paper we describe a methodology that allows attenuation measurements at infrared to estimate mean concentrations of atmospheric molecular components along quasi-vertical rectilinear paths. A number of ground passive infrared stations is needed, distributed along a baseline in the area of interest, and spaceborne monochromatic infrared sources. Measurements made along all rectilinear paths defined by each satellite pass above the site, are processed following an ad hoc tomographic inversion technique to provide the 2D vertical distribution of the atmospheric molecular components of interest. Some simulation results are presented to demonstrate the applicability of the cited tomographic technique. Carbon Monoxide has been considered as the molecular test species in the simulations, based on standard atmospheric models.
