Light fields in the clear natural water as an evidence of own water heterogeneity

摘要

The problem of optical constant of seawater to in situ measured light fields in the clear natural waters is under discussion. A precise radiative transfer prediction for the water reflectance demonstrates significant discrepancy in comparison to the field data. It was shown that to meet agreement between the empirical and theoretical reflectance values it would be necessary to increase the backscattering. On the contrary, the interpretation of diffuse attenuation coefficients for downward irradiance tends to underestimate the light absorption in the water. A conception of own water heterogeneity is proposed. This enables to explain the most of inconsistencies.
