Description
Observations from space are essential to assist the successful understanding and management of climate change, one of the biggest challenge facing mankind in this century. Establishing the necessary accurate long-term data records requires coordinated activities involving all relevant parties, i.e. environmental and space agencies, climate science community and measurement experts. Over the last few years new programmes addressing the needs for climate data records have been initiated, e.g. in Europe the ESA Climate Change Initiative (CCI) and more recently the Copernicus Climate Change Service (C3S). We report on ongoing efforts within these programmes to build harmonised and well characterised long term data records of vertically-resolved ozone concentration, which constitute one of the primary atmospheric Essential Climate Variables. More specifically we discuss the current state-of-the-art and the challenges to ensure continuity in time and data quality, with a view on requirements for future ozone observational systems.
