HICO Data User AgreementUser Agreement • October 3rd, 2011
Water transparency is a useful index of water quality or productivity and is used in many environmental studies. Because of the complicated constitutes and rapid variation in coastal water, it is difficult to retrieve its water transparency. HICO data have much greater spatial, spectral resolution and high Signal to Noise Ratio than current space borne ocean color imagers, and the data are of great interest for studying the dynamics of the coastal ocean waters. And to solve the difficulty to retrieve coastal water transparency, we adapt and develop semi-analytical and empirical algorithms to estimate the water transparency in Pearl River Estuary (PRE) of South China from HICO products by combined analysis of in situ water spectra and radiative transfer simulations. The development of the algorithms is based on the use of a comprehensive in situ bio-optical and spectra dataset. The algorithms will be validated using an extensive set of in situ measurements of the Secchi depth in synchro
