内容記述 |
This paper examines a technique for retrieving chlorophyll a concentration by using field spectroradiometer data with fluorometer data and the Sea-viewing Wide Field-of-view Sensor (Sea WiFS) data. Spectroradiometer data were coupled with fluorometer data to find out the best suited bands ratio to monitor the chlorophyll a concentration for inland water. Remote sensing reflectance measurements were used to evaluate the performance of several default ocean color chlorophyll algorithms for SeaWiFS data. Remote sensing reflectance data from a spectroradiometer and in situ chlorophyll a data from a fluorometer were collected for Lake Abashiri, and SeaWiFS data for Lake Saroma were used. It was found that the chlorophyll a concentration from fluorometer and reflectance from spectroeradiometer lies in exploiting the signal provided by the chlorophyll a red absorption peak near 670nm. The proposed estimation model based on two-band ratio of reflectance 670 and 700nm provided a good correlation for in situ chlorophyll a, compared with blue-green two-band ratio model. |
