Resumo
Lidar measurements provide information to determine the cirrus clouds optical and geometrical properties. Those quantitative determinations require properly determined backscatter to extinction ratio coefficients. In this work we analyze and combine different methods used to obtain the cirrus clouds parameters profiles (optical depth, extinction and backscattering coefficients). We applied the proposed combined method to several cirrus lidar signal measured over Buenos Aires, Argentina and we analyze one occurrence over Cuba. We conducted a critical analysis of the results. We obtain the parameters using the conventional approach, double ended and Back-TOD partially methods, all based on the Klett method. The goal of this work is to determine the backscatter to extinction ratio. We analyze and compare the results with old and recent data.
