ECMWF ERA-Interim: monthly ozone climatology source data from satellite and ozonesondes (1966-1993)

This monthly ozone climatology dataset was produced from a combination of satellite and ozonesonde data from 1966 to 1993. It was produced following the method described by Fortuin and Langematz (1994) and is used by the radiation code within the ECMWF IFS to generate the output from from ERA-Interim reanalysis model runs (see Dee et al. 2011 for further details).

The ozone values are given in ppmv on 36 vertical pressure levels and 19 latitudinal bands. These are then internally interpolated to the grid used by the model before entering the radiation scheme.

The 19 latitudinal bands the data are present are at: -90, -80, -70, -60, -50, -40, -30, -20, -10, 0, 10, 20, 30, 40, 50, 60, 70, 80, 90 degrees.

The climatology was originally produced by Fortuin and Langematz (1994) in response to the many GCMs at that time that used a prescribed ozone field. The aim was to generate a reference field with the required spatial and temporal coverage for use within modelling studies.

Statement: Data are generated by the ERA-Interim project team at European Centre for Medium-Range Weather Forecasts (ECMWF) as part of the input into the ECMWF IFS. These data were then extracted from the ECMWF system by Alessio Bozzo at ECMWF and sent to Alison Ming, University of Cambridge, for preparation before submission to Centre for Environmental Data Analysis (CEDA) for ingestion into the archive.
