Abstract
Retrievals of inherent optical properties (IOPs) and chlorophyll-a concentration (Chla) were investigated for AVNIR-2 images with 30 m spatial resolution and four bands in the southwest tropical lagoon of New Caledonia. We corrected the atmospheric and sea-surface reflectance iteratively through the retrieval of IOPs. After an additional correction of seafloor reflectance, the estimated IOPs and Chla agreed well with the in situ measurements even in the lagoon areas. This study provides a method to allow a local optimal estimation of IOPs and Chla with a high-resolution sensor by preparing the candidate spectra for the target areas.
