CALIPSO CALIOP Regional Particulate Backscattering Coefficient (Bbp) Data, version 1

This BBP data suite provides regional estimates of the particulate backscattering coefficient, bbp(532 nm) (units: m⁻¹) derived from the CALIOP lidar aboard CALIPSO. CALIOP’s active 532-nm channel enables nighttime and high-latitude retrievals where passive ocean-color sensors are often limited, and published evaluations show that space-lidar bbp is a strong complement to ocean color and in situ float observations for upper-ocean optical and biogeochemical studies. Typical uses include time-series analysis of particulate optics, high-latitude/seasonal studies, and providing independent constraints for algorithms that link bbp to carbon stocks or phytoplankton dynamics. Users should note CALIOP’s limited subsurface penetration (~a few optical depths) and apply the product’s recommended screening (day/night, quality flags) before analysis.

Geophysical variables in this suite include:
