Remote sensing from Earth-observing satellites is now providing valuable information
about ocean phytoplankton distributions. This paper presents the new ocean subsurface optical properties
obtained from two space-based lidars: the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP)
aboard the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations satellite and the Advanced
Topographic Laser Altimeter System (ATLAS) aboard the Ice, Cloud, and land Elevation Satellite-2
satellite. Obtaining reliable estimates of subsurface biomass necessitates removing instrument artifacts
peculiar to each sensor, that is, polarization crosstalk artifacts in the CALIOP signals and after pulsing
effects arising from the ATLAS photodetectors. We validate the optical properties derived from the
corrected lidar backscatter signals using MODerate-resolution Imaging Spectroradiometer ocean color
measurements and autonomous biogeochemical Argo float profiles. Our results support the .....
