Short summary

This paper assesses biases in the 1064 nm calibration of the Cloud Aerosol Lidar with Orthogonal Polarization (CALIOP) due to signal attenuation differences at 1064 and 532 nm caused by stratospheric aerosols. Multi-channel measurements from the Stratospheric Aerosol and Gas Experiment suggest the bias ranges from 1 %–2 % for background conditions to over 5 % for high aerosol loads. Implications for CALIOP 1064 nm extinction retrievals and cascading errors in multi-layer scenes are discussed.
