ESA CCI Ocean Colour ECV

Observations from space provide unique information which greatly aids understanding and management of climate change. However, satellite data are often limited by a lack of continuity and are not always adequately preserved over time. This makes it difficult to keep a reliable long-term record. It is also important to ensure that the data are of sufficient quality to serve the needs of climate research. In this context, the Global Climate Observing System (GCOS) identified a set of Essential Climate Variables (ECVs) and a set of requirements for satellite data to meet the needs of the community.

The goal of the ESA CCI project is to provide stable, long-term, satellite-based ECV data products for scientists, to help categorise the state of the global climate systems and enable long-term monitoring. This will improve management of climate change through efficient global coverage and continuous measurements from satellites, informing researchers about the climate system.

As part of the Climate Change Initiative, PML scientists will contribute to establishing lasting and transparent access to results for global climate, scientific and operational communities to enhance data sharing and knowledge exchange.
