CALIOP receiver system transient response of 532 nm channel is not ideal. It is analyzed by using Version 3.01 (V3), Version 4.0 (V4) Level 1 (L1) profile data and Level 2 (L2) atmospheric aerosol and cloud layer data. The transient responses are compared in different time and location, different clear atmospheric conditions, different nadir and different version of data. In addition, the influence of surface signal strength on the transient response is explored. Results show that the version change and the nadir change have no effect on the transient response; the clearest air condition is necessary to choose; desert (tIGBP=16) is the better object for the analysis of transient response; the signal strength of surface attenuated backscatter has influence on the transient response. These strengths less than 0.40 km-1sr-1are weak signal, needed to be removed.
