Paper Abstract
A relationship between depolarization ratio and surface concentration of particulate organic carbon (POC) is developed
from the NASA SeaWiFS Bio-optical Archive and Storage System (SeaBASS) in situ measurements and the Cloud-
Aerosol Lidar with Orthogonal Polarization (CALIOP) active lidar measurements. This relationship provides an
algorithm for estimating global POC from satellite or airborne polarization lidar measurements. Application of this
relationship to CALIOP data indicates that the estimates of POC ranges from about 3.3 mg/m3 within the South Pacific
Subtropical Gyre to 1.2×103 mg/m3 in the area near land are in good agreement with Moderate Resolution Imaging
spectroradiometer (MODIS) POC products. Our results present depolarization ratio as a valuable tool for evaluating
global POC predictions in ocean ecosystem. The application of the algorithm to a 7-year of CALIOP depolarization ratio
mean values revealed patters of seasonal and interannual variability of POC. By comparing the results averaged over the
entire study region and entire season for each year separately, we found that the lowest POC occurred in 2013 and the
highest POC occurred in 2008.
