Abstract:
The accuracy characteristics of the temperature reconstructing from realistic lidar signals of molecular light scattering are analyzed. The temperature was sounded by means of two Rayleigh lidars: the first with a mirror 2.2 m in diameter at λ = 532 nm operating in the upper stratosphere and mesosphere (30-75 km) and the second with a mirror 1 m in diameter at λ =353 nm operating in the lower and middle stratosphere (13-35 km). Total, random, and systematic errors of temperature calculation and their dependence on the altitude were estimated as well as deviations of the temperature profiles depending on the error values. The lidars are shown to ensure satisfactory accuracy of the temperature measurement within the altitude range from 13 to 30 km and from 30 to 60 km, respectively. The rms error at maximum altitudes in both cases does not exceed 10 K. To decrease the error, it will suffice to increase the pulse accumulation time. A more drastic alternative is the increase of the lidar energy potential. Due to the use of a shorter wavelength of UV range (353 nm) and taking into account the pulse attenuation caused by the molecular light scattering, the altitude range from 13 to 35 km has been mastered by us for temperature measuring by the Rayleigh method.
