SATACI (SATellite observations to improve our understanding of Aerosol-Cloud Interactions and associated Radiative Forcing using satellite data records generated by the ESA Climate Change) is one of the projects under the European Space Agency Climate Change Initiative Programme.

It is a science exploitation study which utilises multiple Essential Climate Variable data products developed via ESA's Climate Change Initiative (CCI) to improve understanding the climate system that are directly relevant to IPCC assessments.
