Abstract
Aerosol and temperature are important parameters for forecasting the weather. Rotational Raman signals of atmospheric molecules and an elastic signal of the molecule and aerosol give good information about the temperature and aerosol extinction and backscattering coefficients. For a rotational Raman signal, we have designed a new kind of lidar signal receiving system which can sum different rotational quantum numbers from J=2, to 9 and J=11, to 20. This integration signal gives a good signal to noise ratio when compared with the temperature lidar system which use an interference filter for a single quantum number. From this new system, we can obtain the temperature parameter and aerosol scattering coefficient with good signal to noise ratio the (SNR) with a normal laser and a small telescope up to several kilometers. Temperature profiles and aerosol profiles show different shapes in different weather conditions.
