Global distribution of cloud droplet effective radius from POLDER polarization measurements
International audience Polarization measurements from the spaceborne POLDER instrument are used to estimate the droplet effective radius of liquid-phase clouds. Eight months of measurements have been processed. Seasonal averages have been generated and are discussed here. The measurements confirm th...
