SPARC Data Initiative Trace Gas and Aerosol Climatologies

The goal of the SPARC Data Initiative is to improve our knowledge and understanding of the overall uncertainty in chemical trace gas and aerosol observations from a multi-national suite of limb-viewing satellite instruments. This knowledge is crucial when using datasets from multiple instruments for data merging activities and the validation of chemistry-climate models. The SPARC Data Initiative Team, which consists of representatives from each instrument team and data analysts, has compiled zonal mean monthly mean time series of all available chemical trace gas and aerosol data in a common format (NetCDF). Data description and analyses will be summarized in a peer reviewed SPARC report. Report conclusions are based on the existing data versions at the time of the report formulation and should be used as basis for the evaluation of updated versions.

Data Access

The tracer and aerosol climatologies will be made public and freely available for data users after publication of the SPARC Data Initiative Report. The datasets will be updated with newer data versions as soon as they become available and have undergone required quality controls. A person wishing to use any portion of the SPARC Data Initiative datasets is requested to submit contact name of researcher, email address, affiliation, and a short summary of the proposed work via the online interface and to accept the SPARC Data Initiative policy document online in order to acknowledge having read it and to agree to use the data in accord with these guidelines. This information will be communicated to the team leaders and the various instrument team representatives. During the present phase (before the publication of the SPARC report) access will be granted personally after following the above instructions.

If you have read and agree to the SPARC Data Initiative policy document please follow the link below to request access to the data. If you do not have a CEDA account (previously BADC/NEODC account) then you will need to register as part of the process.
