Characteristics of upper-ocean biology that can be derived from current and potential future satellite lidar missions. DOI: https://doi.org/10.1525/elementa.331.t3

Upper-ocean biology characteristicCurrent satellite lidar: CALIOP on CALIPSOFuture satellite lidar: ocean-optimised

 
Phytoplankton biomass Surface-weighted values consistent with weighting of passive ocean colour estimates Vertically resolved profiles to ~ three optical depths; separate estimates of pigment absorption and CDOM (with addition of 355-nm measurements) 
Phytoplankton composition and succession Not available Potential for crude PFT discrimination from depolarisation and wavelength dependence of backscatter 
Phytoplankton bloom phenology and bloom state Biomass retrieval under conditions impossible for ocean colour: high-latitude winter, night, through aerosol and optically thin clouds, between clouds in broken cloud systems, and in the proximity of ice; ~ monthly resolution Same plus vertically resolved profile of phytoplankton abundance to ~ three optical depths 
Organic carbon pool Surface-weighted estimates of POC Vertically resolved estimates of POC and CDOM. 
Particle size distribution Not available Slope of particle size distribution from particle backscatter at two wavelengths 
Phytoplankton physiology Not available Nutrient and radiative stress from day-night comparisons of Chl-a fluorescence
