Decadal changes in Arctic Ocean Chlorophyll a: bridging ocean color observations from the 1980s to present time

This dataset is related to the article "Decadal changes in Arctic Ocean Chlorophyll a: bridging ocean color observations from the 1980s to present time" In Remote Sensing of Environment by Laurent Oziel, Philippe Massicotte, Marcel Babin and Emmanuel Devred. It provides the longest (but non-continuous) ocean color time-series ever produced for the Arctic Ocean (37 years long between 1979 and 2016). To achieve this time-series, the raw data from the Sea-viewing Wide Field-of-View (SeaWiFS, 1998-2010) and the MODerate resolution Imaging Spectroradiometer (MODIS, 2003-2016) ocean-color sensors were re-processed to ensure compatibility with the first ocean color sensor, namely, the Coastal Zone Color Scanner (CZCS, 1979-1986). The dataset was carefully quality-controlled with a bio-regional approach. Despite the temporal gaps between 1986 and 1998 due to the absence of ocean color satellite, the time series (here delivered as climatologies) is suitable to establish a baseline of phytoplankton biomass for the early 1980s and to derive decadal change in Chlorophyll a.

本数据集与发表于《Remote Sensing of Environment》的论文《Decadal changes in Arctic Ocean Chlorophyll a: bridging ocean color observations from the 1980s to present time》相关，作者为Laurent Oziel、Philippe Massicotte、Marcel Babin及Emmanuel Devred。该数据集构建了北冰洋有史以来最长（但非连续）的海洋颜色时间序列，时间跨度达37年（1979年至2016年）。为生成该时间序列，研究团队对海洋宽视场传感器（Sea-viewing Wide Field-of-View, SeaWiFS，1998-2010年）与中分辨率成像光谱仪（MODerate resolution Imaging Spectroradiometer, MODIS，2003-2016年）的原始海洋颜色观测数据进行了重新处理，以确保其与首台海洋颜色传感器——海岸带水色扫描仪（Coastal Zone Color Scanner, CZCS，1979-1986年）的数据兼容性。本数据集采用生物区域化方法开展了严格的质量控制。尽管由于缺少海洋颜色卫星传感器数据，1986年至1998年间存在时间间隙，但本时间序列（本次以气候态数据形式发布）可用于建立20世纪80年代初浮游植物生物量的基准基线，并推导叶绿素a的年代际变化规律。
