  • Slide 3
  • Year without summer 1816 (F. Arfeuille) Investigate the climatic impacts of the strongest volcanic eruptions of the last 700 years. Tools: AER 2D aerosol microphysics model CCM SOCOL vs2 (MEZON coupled to ECHAM4) SOCOL runs include stratospheric aerosols taken from AER model output. Solar spectral irradiance from Dalton minimum reconstruction. Sea Surface Temperatures from coral/tree rings reconstruction. T31L39 resolution. Approach: Ensemble runs around 1815-1818 with different volcanic scenarios, SST forcing, IACETH 3
  • Slide 4
  • The middle atmosphere response to the short-term variability of the solar activity (A.P. Shapiro) To understand the variability of the middle atmosphere state on monthly time scales and evaluate the contribution of the different driving processes. SNF funded Tools: CCM SOCOL vs2 Approach: Short-term (1 year) and medium-term (10 years) ensemble simulations of the atmosphere driven by daily spectral solar irradiance. Analysis of the satellite and ground-based data. Status: All runs have been completed, the analysis is ongoing. IACETH 4
  • Slide 5
  • Nowcasting of the middle atmosphere state (T. Egorova) To understand the influence of short-term variability of the solar irradiance and energetic particles on the middle atmosphere. Learn how to manage near-real-time operation and visualization. FP7 funded, SOTERIA (Solar-TERrestrial Investigations and Archives) Tools: CCM SOCOL vs2 extended to include a complete representation of ion chemistry. Approach: Ensemble simulations of the middle atmosphere state driven by near-real-time information about spectral solar irradiance and energetic particles. Status: Operational service from March 2011 IACETH 5
