  1. COSMIC WEATHER, ATMOSPHERIC NANOAEROSOLS, and HUMAN HEALTH A.A. Lushnikov, Yu.S. Lyubovtseva, V.A. Zagaynov, and A.D. Gvishiani Geophysical Center of RAS, Moscow, Karpov Institute of Physical Chemistry, Moscow

  2. RIGHT AFTER THE SUN FLARE

  3. COMING UP • Introduction • Cosmic weather and electrical state of the atmosphere • Nanoaerosols, where are they from? • Ion - aerosol interactions and cloud formation: from nanos to CCN • Nanos – interactions with human organisms • Concluding remarks

  4. INTRODUCTION:ATMOSPHERIC AEROSOLS • Clusters (size<1 nm) • Nanoparticles (1 -- 50nm) • Submicron particles (50 – 100nm) • Micron particles (100 – 1000 nm) • Coarse particles (>1000nm)

  5. Cosmic rays induced aerosol is coming up COSMIC RAYS COAGULATION ATMOSPHERIC IONS CLOUD CONDENSATION NUCLEI NUCLEATION CLOUDS CONDENSATION
