Remote Sounding of the Stratosphere by the Occultation Method: The ORA Experiment

Part of the Lecture Notes in Physics book series (LNP, volume 607)


The occultation technique is based on recording of the sun light above the horizon. Its benefit resides in the derivation of an absolute quantity (the slant path optical thickness) through the measurement of a relative signal. The ORA experiment is presented together with the inversion method used to retrieve the atmospheric components.
