OceanColour, part of the Ocean Colour Climate Change Initiative (CCI), is a groundbreaking project dedicated to advancing the understanding of ocean color through innovative research and development. The initiative focuses on creating precise algorithms that conform to the Global Climate Observing System (GCOS) requirements, ensuring the delivery of reliable, error-characterized global satellite data products gathered from various sensors.

OceanColour aims to generate a comprehensive time series of multi-sensor satellite data crucial for climate research and modeling, particularly by optimizing the use of MERIS data within climate data records. To enhance scientific collaboration, the project fosters interdisciplinary cooperation among international Earth observation and climate research communities.

Employing a flexible data reprocessing approach, OceanColour regularly updates data processing methodologies by integrating ongoing advancements in atmospheric correction, in-water algorithms, and bias correction techniques. This ensures that researchers have access to the most accurate and current ocean color datasets from numerous ESA and NASA missions, driving forward important climate studies.
