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

CONCLUDING REMARKS • From cosmic rays to clouds is one of the most important processes. The very existence of life is not possible without aerosols. • Cosmic weather is the important factor that exerts formation of secondary aerosols in the atmosphere
