Recent Variability of the solar spectral
irradiance and its impact on climate modelling

• 4. Climate Impact of SSI measurements
• 4.1 Impact on heating and photolysis rates
• (a) Spectral Resolution of radiation codes
• Stress the importance of spectral resolution in
  the climate models radiation codes designed for
  studies of solar cycle effects (built on Fortster
  et al. 2011)
• (b) Assessment of the effects of the SSI data
  sets and the difference of their impacts
• On heating rates (radiation)
• On photolysis rates (chemistry)
• Comparison of results from published work, assess
  their differences as possible, stating that we
  are aware of them
• The above to be completed with the SSI data sets
  recommended from groups (2) and (3) need for a
  recommended estimate !
• Stress the necessity of a consistent set of runs,
  based on a (set of) recommented estimate
• We foresee 3-4 figures in this part, possibly
  merged in 2

• 4.2 Temperature response in climate models
  Recent developments
• Recommendation and/or a scenario for the future
  evolution of solar irradiance, so that a figure
  can be reproduced following the work o Jones et
  al.
• Essential!!
• (??) Preparation of a figure of the response of
  tropical temperatures in a set of models run for
  CMIP5 imposing solar cycle variations
