摘要

Abstract

This paper suggests a group of statistical algorithms for calculating the total absorption co-efficients based onin situ data of apparent optical property and inherent optical property collected with strict quality assurance according to NASA ocean bio-optic protocols in the Yellow Sea and the East China Sea in spring 2003. The band-ratios ofR rs555

R rs555 are used in the algorithms to derive the total absorption coefficients (a 1) at 412

440

488

510

532 and 555nm bands

respectively. The average relative errors between inversed and measured values are less than 25.8%

with the correlative coefficients (R 2) being 0.75–0.85. Error sensitivity analysis shows that the maximum retrieval error is less than 24.0% at ±5% error inR rs's. So the statistical algorithms of this paper are practicable. In this paper

the relations between the total absorption coefficients at 412

532

555 nm and that of 440nm are also studied. The results show that the relations between the total absorption coefficients of 400–600 nm and that of 440 nm are correlated well and all of their correlative coefficientsR 2 are greater than 0.99. Furthermore

a regression analysis is also done for the slope of the linear relations and wavelengths

and theR 2 is also 0.99. Thus it is possible to retrieve other bands' total absorption coefficients with only one band absorption value

which significantly reduce the number of unknown parameters in studying other ocean color related problems.
