| Abstract: | Spatial-temporal variation trends of Chlorophyll-a concentration in Lake Dianchi were analyzed based on MERIS data.First,three popular retrieval algorithms of Chlorophyll-a concentration were calibrated by field measurements.It was found that three-band model was the best one with higher estimation accuracy.Then,the optimized three-band model was applied to 57 MERIS images from 2003 to 2009 which were pre-processed through geometric correction,atmospheric correction,etc.At last,a series of maps about Chloro... |
| Keywords: | Chlorophyll-a spatial-temporal variation Lake Dianchi MERIS data three-band model |
