Computation of the Attenuated Backscattering Coefficient by the Backscattering Lidar Signal Simulator (BLISS) in the Framework of the CALIOP/CALIPSO Observations

This paper presents the Backscattering Lidar Signal Simulator (BLISS), an end-to-end lidar simulator developed by Centre National d’Etudes Spatiales (CNES). We computed constant multiple-scattering (MS) coefficient of BLISS with a Monte Carlo (MC) code in framework CALIOP/CALIPSO observations for different homogeneous and plane-parallel stratocumulus cirrus cloud geophysical scenes. The MS varies from 0.46 to 0.63. Then we evaluated Level 1 products BLISS. Above in-cloud relative difference between attenuated backscattering vertical profile simulated MC is smaller than 0.5% under single-scattering regime 10% (30% if optical depth large) regime, thus confirming robustness
