  • Bookmarks
    • Mailing lists
      • RFMIP-SpAer mailing list
        Mailing list for questions, comments, and discussion about simulations using the CMIP6 prescription of aerosol optical properties.
      • RFMIP-IRF mailing list
        Mailing list for questions, comments, and discussion about a) offline radiation calculations using prescribed atmospheric conditions, and b) diagnostics and calculations of clear-sky aerosol instantaneous radiative forcing.
      • RFMIP-ERF mailing list
        Mailing list for questions, comments, and discussion about fixed-SST simulations to diagnose effective radiative forcing.
    • Publications
      • Assessing aerosol instantaneous radiative effect
        This paper describes results from a pre-RFMIP exercise following the RFMIP-IRF-AER protocol in which global snapshots are used to assess errors in aerosol instantaneous radiative effect by comparison to high-spectral resolution models.
      • CMIP6 and RFMIP specification of aerosol optical properties
        This manuscript describes the specification of aerosol optical properties and cloud-modifying properties developed for CMIP6. The specification can be used for all simulations outside of AerChemMIP; if another prescription is used then historical simulations with this specification are the path to contributing to the 'specified aerosol' component of RFMIP.
      • Why use fixed sea-surface temperatures to infer ERF?
        This paper explains why RFMIP uses 'fixed-SSTs', i.e. integrations in which sea surface temperature and sea ice concentrations are fixed at pre-industrial values, to estimate effective radiative forcing, as opposed to regressions following a step change.
      • RFMIP protocol description
        This is the formal description of the RFMIP protocol published as part of the CMIP6 special collection in the on-line journal Geoscientific Model Development.
      • Background and Motivation
        • Effective radiative forcing in CMIP5
          This paper demonstrates the large range in effective radiative forcing to which the CMIP5 models were subject, although precision is limited by the available information. RFMIP plans to use 'fixed-SST' simulations to make such estimates more accurately and uniformly for CMIP6.
        • Errors in clear-sky radiative transfer
          This paper assess the range of errors in radiative transfer parameterizations in the simplest case - in clear skies with no aerosols. RFMIP will extend this kind of analysis to global scales, focusing on instantaneous radiative forcing relevant to CMIP experiments.
    • RFMIP-IRF-Aerosol
      • RFMIP Aerosol IRF protocol tips
        This is the current version of the document providing details and helpful suggestions for providing data to the aerosol IRF experiments.
