ESA Ocean Colour Climate Change Initiative (Ocean_Colour_cci): Monthly climatology of global ocean colour data products, Version 5.0

The ESA Ocean Colour CCI project has produced global, level 3, binned multi-sensor time-series of satellite ocean-colour data with a particular focus for use in climate studies.

This dataset contains a monthly climatology of the generated ocean colour products covering the period 1997 - 2020.

Data products being produced include: phytoplankton chlorophyll-a concentration; remote-sensing reflectance at six wavelengths; total absorption and backscattering coefficients; phytoplankton absorption coefficient and absorption coefficients for dissolved and detrital material; and the diffuse attenuation coefficient for downwelling irradiance for light of wavelength 490nm. Information on uncertainties is also provided.

Please note, data from December 2020 onwards are affected by an anomaly discovered after production and resulting in a spurious jump in remote sensing reflectance. The anomaly has been corrected in the version 5.0.1 of the dataset available through the Copernicus Climate Change Service (https://doi.org/10.24381/cds.f85b319d)

Version 6.0 of this data is now also available here: https://doi.org/10.5285/5011d22aae5a4671b0cbc7d05c56c4f0

欧洲空间局（ESA）海洋颜色综合分析项目（Ocean Colour CCI）已生成全球范围内的三级，分箱式多传感器时间序列卫星海洋颜色数据集，该数据集特别关注其在气候研究中的应用。本数据集包含覆盖1997年至2020年期间生成的海洋颜色产品的月度气候学数据。数据产品包括：浮游植物叶绿素-a浓度；六波长的遥感反射率；总吸收率和背向散射系数；浮游植物吸收系数以及溶解和碎屑物质的吸收系数；以及波长为490nm的下行辐照度的漫射衰减系数。同时，还提供了不确定性的相关信息。请注意，自2020年12月起的数据受到生产后发现的异常影响，导致遥感反射率出现虚假的跳跃。该异常已在数据集的5.0.1版本中得到修正，可通过哥白尼气候变化服务（https://doi.org/10.24381/cds.f85b319d）获取。本数据集的6.0版本也已在此处提供：https://doi.org/10.5285/5011d22aae5a4671b0cbc7d05c56c4f0。
