Rotational Raman lidar
Abstract
The rotational Raman scattering induced by a laserpulse transmitted through the atmosphere, will include information about both the temperature and extinction of the atmosphere. The scattered intensity allows the calculation of the differential corss-sections of the air molecules. Two parts of the rotational Raman spectrum, which are selected by means of a polarization filter and two interference filters, contain the information about the temperature. This Raman scattering was detected at distances to a maximum of 1.5 km from which the differential cross sections of O2(7) and N2(6) were calculated.
