Atmospheric correction and inherent optical property 1 estimation in the southwest New Caledonia lagoon using 2 AVNIR - 2 high - resolution data 3 4

11 Retrievals of inherent optical properties (IOPs) and Chlorophyll-a concentration (Chla) was 12 investigated for AVNIR-2 images with 30-m spatial resolution and four bands in the southwest 13 tropical lagoon of New Caledonia. We corrected the atmospheric and sea-surface reflectance 14 iteratively through the retrieval of IOPs. After an additional correction of sea floor reflectance, 15 the estimated IOPs and Chla agreed well with the in situ measurements even in the lagoon 16 areas. This study provides a method to allowing a local optimal estimation of IOPs and Chla 17 with a high resolution sensor by preparation of the candidate spectra for the target areas. 18 19 ird -0 08 62 97 7, v er si on 1 18 S ep 2 01 3 Author manuscript, published in "Applied Optics 52, 2 (2013) 182-198"
