Abstract
We presented model estimates of daily average direct radiation effects of smoke aerosol in the solar spectral range obtained using observations at Tiksi station in the period of anomalously high black carbon (ВС) concentration in the near-surface atmospheric layer (July 2014). These data are compared with radiation effect of aerosol characteristic for typical summer conditions in this region. It is shown that the monthly average radiation effects caused, on the one hand, by variations in optical characteristics of background aerosol and, on the other hand, by short-term outflows of BC from forest fires to the region of observations are comparable in value.
