Abstract

The radiation effects of aerosol in clear sky under continental aerosol (Meteorological Observatory of MSU (Russia), Lindenberg Observatory (Germany)), over semi-desert areas (Israel) and Arctic district at the Tiksi International Hydrometeorological (Russia) observatory were estimated using the mesoscale COSMO-Ru model. The effect of aerosol on the surface air temperature is also was investigated. For the present study we use the aerosol dataset from CIMEL (AERONET) sun photometer measurements and the data of shortwave radiation components based on reliable instruments Kipp&Zonen. The application of the new MACv2 climatology radiation model provides the annual average relative error of the total global radiation which does not exceed 25 W/m². We suggest that in clear sky conditions the sensitivity of air temperature at 2 meters to aerosol in all considered geographical areas lie within 0.9°C per 100 W/m² change in shortwave net radiation changes.
