长江经济带叶绿素a

长江经济带叶绿素a产品数据主要面向长江经济带城市群典型环境参数研究、跨区域监测的应用需求，基于固定地面站点监测、移动平台监测和Landsat、哨兵2等多源遥感观测等多平台数据源，主要记录了2020年、2021年和2022年1月-6月的重庆至上海长江干流及周边的重点湖库的叶绿素a浓度，数据量162.8GB

The Chlorophyll-a (Chl-a) product dataset for the Yangtze River Economic Belt is primarily developed to support research on typical environmental parameters of urban agglomerations within the Yangtze River Economic Belt and applications of cross-regional environmental monitoring. It is constructed using multi-platform data sources including fixed ground station monitoring, mobile platform monitoring, and multi-source remote sensing observations such as Landsat and Sentinel-2. The dataset primarily records the chlorophyll-a concentrations in the main stream of the Yangtze River from Chongqing to Shanghai and their surrounding key lakes and reservoirs, covering the period from January to June of 2020, 2021 and 2022. The total size of the dataset is 162.8 GB.
