论文摘要
Quantitative bio-optical inversion for inland water monitoring, resolving phycocyanin absorption features (620 nm), chlorophyll-a absorption (665 nm), and total suspended matter scattering across complex Case-2 inland water bodies.
核心方法论发现
620 nm phycocyanin absorption dip isolates toxic cyanobacteria blooms from benign green algae with zero false-alarm confusion.
Semi-analytical bio-optical inversion models retrieve chlorophyll-a concentrations across 0.5–250 µg/L without requiring site-specific statistical re-calibration.
Acid mine drainage plumes are mapped by automated detection of dissolved ferric iron and secondary jarosite/schwertmannite precipitates.
物理原理与反演方法论
Inversion of subsurface water-leaving reflectance through semi-analytical bio-optical forward models parameterised with absorption and backscattering coefficients of pure water, phytoplankton, CDOM, and mineral particles.
