[PEM27-06] Derivation of the stratospheric temperature with the sodium lidar
Keywords:Sodium Lidar, Rayleigh scattering
A sodium LIDAR observations use the resonance scattering from sodium atoms in the sodium layer between 80 and 110 km. We also successfully receive Rayleigh scattering light from the atmosphere between about 30 and 60 km. The upper height depends on the background noise level, while the lower height limit is determined by contamination of Mie scatter light. We calculated the temperatures between November 2011 and February 2012 with a 1 km resolution and compared them with the calculated atmospheric temperatures with the ECMWF (The European Centre for Medium-Range Weather Forecasts) data. The comparison shows a reasonable agreement.
This new addition of the datasets will make it possible to investigate the correlation of the temperature variation between the upper stratosphere (30-50 km) and the upper mesosphere/lower thermosphere (80-110 km). Furthermore, the observed stratospheric temperature will improve the accuracy of the millimeter wave observations.
