Service Description: Satellite-based assessments of ocean color began in 1978 with the launch of the Coastal Zone Color Scanner (CZCS) aboard the NASA Nimbus 7 satellite. Following a decade-long break in observations, there have been continuous satellite ocean color measurements since 1997 with Sea-Viewing Wide Field-of-View Sensor (SeaWiFS), followed by Medium Resolution Imaging Spectrometer (MERIS), Moderate Resolution Imaging Spectroradiometer (MODIS),Visible Infrared Imaging Radiometer Suite (VIIRS),Ocean Land Color Instrument (OLCI), Second Generation Global Imager (SGLI) and Ocean Color and Temperature Scanner (OCTS) with additional sensors in development. Data gaps from individual sensors are common due to revisit cycles, cloud cover, and spurious retrievals resulting from a host of confounding atmospheric and aquatic conditions. Some of these issues have been addressed by combining data from multiple sensors and creating a consistent, merged ocean color product (e.g., surface ocean chlorophyll-a concentration). The ESA Ocean Color CCI (OC-CCI) project, led by Plymouth Marine Laboratory (PML), has produced a consistent, merged chlorophyll-a product from SeaWiFS, MODIS, MERIS and VIIRS, spanning the years 1997 to 2019 (Sathyendranath et al., 2018). The merged multi-sensor product will be updated in both time and with data from additional sensors (e.g., OLCI) as part of the Copernicus Climate Change Service (C3S) and the Copernicus Marine Service (CMEMS) that will continue the time series on an operational basis. Future OC-CCI releases will also include algorithmic improvements developed under the CCI+ initiative. Chlorophyll-a concentrations for this indicator are obtained from the global ocean, 4 km spatial data from multiple sensors and creating a consistent, merged ocean color product for each pixel within a country’s EEZ.For purposes of this sub-indicator, reporting year values are compared to a baseline of years 2000 to 2004. The baseline climatology was calculated as the mean of the 5 years of each month by pixel (e.g., mean of 5 years of January) resulting in a 5 year mean of each calendar month over the period 2000 to 2004. The processing steps are outlined.
