An algorithm will be described, relating the absorption and backscattering coefficients of turbid water with the attenuated backscatter retrieved by the Cloud – Aerosol LIDAR with Orthogonal Polarization (CALIOP) instrument (on the CALIPSO satellite), when combined with surface reflectance data from the Moderate-Resolution Imaging Spectroradiometer (MODIS). The algorithm uses the total attenuated backscatter at 532 nm from the CALIOP sensor, and the MODIS channel 11 (526nm-536nm) reflectance. This algorithm exploits the combination of active and passive instrumentation to allow the derivation of the separate coefficients. A validation study in Tampa Bay is in progress using monthly field data obtained from the Environmental Protection Commission of Hillsborough County; this study will be described and some preliminary results shown. In addition to results such as those discussed here, using the A-train configuration of CALIPSO and AQUA, this algorithm is expected to add value to future visible LIDAR missions such the Aerosol-Cloud-Ecosystems (ACE) mission.
