Copernicus Climate Change service for Ozone (C3S-312a lot4)

Long-term ozone data sets for climate studies

Within the Copernicus Climate Change service for Ozone KNMI provides (1) the multi-sensor reanalysis (MSR) data and (2) gridded ozone profiles from nadir satellite observations. The ozone multi-sensor reanalysis is a multi-decadal ozone column data record (1970-2016) constructed using all available ozone column satellite datasets, surface Brewer and -Dobson observations and a data assimilation technique with detailed error modelling. The result is a high-resolution time series of 6-hourly global ozone column fields and forecast error fields that may be used for ozone trend analyses as well as detailed case studies.
