Abstract
In the current work, the result of an investigation of temperature effect of smoke aerosol in the summer season over the central part of Yakutia during the period 2004−2014 are presented. The data of ground-based and satellite measurements and also of climate models NCEP/NCAR and ERA-Interim, which are based on regular meteorological observations and aerological and satellite informations are used. It is first showed that a disturbance of atmosphere by aerosol particles which is caused by heat sources of forest area lead to a decrease of solar radiation flow, and, in the presence of a negative phase of upward longwave radiation, a surface air temperature drop is observed.
