Content - Data Assimilation
Data assimilation requires knowledge of measurement and model errors, which, in turn, require knowledge of the true 'underlying system': the middle atmosphere. Therefore, advancement of assimilation techniques requires interaction of assimilators with dynamicists, chemists and users of assimilation products. During annual workshops we bring together assimilators, users of assimilation products, and experts in modelling, measurements and process studies.
Past Workshop themes have included: stratosphere-troposphere coupling; assessment of reanalyses; seamless prediction and model error; chemical data assimilation; gravity wave parameterization; transport errors in assimilated winds.
Recurrent themes of past SPARC Data Assimilation workshops have led to the setup of two SPARC activities, namely:
