Monitoring gaseous emission from terrain through tomographic techniques in the infrared spectral region

The authors propose a study about a system for measuring the flux of gaseous species of interest emitted by the terrain by means of a tomographic method operating in the infrared spectral region. The main components of this system are: a ground network of transmitters-retroreflectors-receivers for IR attenuation measurements, a data-processing both to retrieve the 2D-distribution of the molecular species and to estimate the emission flux by the terrain. CO/sub 2/ emission in the Rapolano Terme area (Italy) has been taken as case study.
