| Abstract;The research focuses on using TM data to monitor water quality in the Changjiang estuarine region. The representative water quality parameter, chlorophyll-a, has estimated from the TM 117-38, 39 on Oct. 13, 1997. 6S code is applied to do atmosphere correction for TM visible bands which is taking gaseous absorption, atmosphere scattering and sun glint into account. The relation analysis suggests the band ratio of log(TM1/TM2) has the largest coefficient with the log(Chlorophyll-a) provided by SeaWiFs on Oct. 9, 1997. Based on this, the linear regression equation: log(chlorophyll-a)=0.752-4.79 log(TM1/Tm2)(R=-0.697) is applied to the whole two scenes. The result suggests that TM data can provide enough information to monitor the distribution of chlorophyll-a. (author abst.) |
