Abstract

In this study, measurements and models are used to test the closure between remote-sensing reflectance and IOPs. Measurements include those by AC9 (Wetlabs, Inc.) and HS6 (HOBI labs, Inc.), while models include both empirical models (e.g., Voss' beam attenuation coefficient model) and radiative transfer model (e.g., Hydrolight). It is found that, generally, AC9 works better than HS6 in providing scattering and backscattering coefficients. HS6 need more accurate calibration; absorption coefficients by AC9 are consistent with those by Spectrix or Spectrometer. Good linear relationship is found between AC9 measured beam attenuation coefficients (c) and the Voss model; while those measurements by HS6 needs some adjustments before feeding to HYDROLIGHT.
