Overview of the Project’s Objectives and Scope
Activity Description
The APARC community has long used reanalysis and analysis datasets to understand atmospheric processes and variability in the troposphere and stratosphere, as well as to validate chemistry-climate models. With the increasing availability of global reanalysis datasets, we are continuing a coordinated activity to compare reanalysis datasets for diagnostics of interest to the APARC community. The objectives of this activity are to understand the causes of differences among reanalyses, to use the results to provide guidance on appropriate usage of reanalysis products in scientific studies, and to support future improvements in reanalysis products through these activities.
The APARC Reanalysis Intercomparison Project (A-RIP) involves close co-operation between reanalysis centres and scientists from APARC and other groups. We host community workshops, organize sessions in international conferences, and are planning a webinar series highlighting papers published in our special issues. The S-RIP Report in the SPARC report series was published in January 2022 (see below).
