Tri-MIP-athlon-2 Tri-MIP-athlon-2

The second joint AerChemMIP / RFMIP / PDRMIP Workshop in support of CMIP6


The joint workshop will focus on new results from the multi-model experiments to quantify changes in composition, the resulting effective radiative forcing and the consequent climate responses. Data from idealised experiments are already available from PDRMIP. Data generated under the RFMIP and AerChemMIP protocols is being made available at

Workshop Goals

Discuss the use of AerChemMIP, RFMIP, and PDRMIP integrations and diagnostics to advance our understanding of composition, forcing and feedback processes for better constraints on past and future projections.

Below is a list of specific questions we are interested in discussing at the workshop:

  • How do the different short- and long-lived constituents contribute to global and regional trends in radiative forcing?
  • How has atmospheric composition (SLCF abundance and budget - ozone and its precursors, aerosols) and oxidizing capacity evolved in response to natural and anthropogenic drivers? What are the implications of composition changes for air quality (e.g., surface ozone, pm2.5, extremes) and radiative forcing?
  • How might future policies (on climate, air quality, and land use) affect the abundances of SLCFs and their climate impacts?
  • How well do the models simulate past changes? Where are the gaps/uncertainties in process-level understanding? What are the causes of inter-model diversity? What are the implications of model biases for future projections?
  • What is the response of natural SLCF emissions to climate change and anthropogenic influences (e.g., land use/cover change)? How do changes in natural emissions influence SLCFs and resulting radiative forcing?
  • What is the role of uncertainty in radiative transfer parametrizations in the calculation of radiative forcing?
  • How does model diversity in radiative forcing translate to diversity in fast precipitation response?
  • What are the robust model responses to tightly specified aerosol radiative forcing from preindustrial to present day?
  • What are the local and remote temperature and precipitation changes induced from SLCF and WMGHG changes?
  • How do SLCFs influence the carbon cycle and terrestrial ecosystems?


The workshop will run from 9:00am on Tuesday 11ᵗʰ June and end at 1:00pm on Friday 14ᵗʰ June. The format will include science presentations (oral and poster) and discussion sessions
