Influence of wildfires in Yakutia on interannual variability of AOT on measurements at stations near Yakutsk

TL;DR

This study examines how large-scale wildfires in Yakutia influence the year-to-year variability of aerosol optical thickness (AOT) based on long-term station measurements near Yakutsk, highlighting fire impacts on atmospheric aerosols.

Contribution

It provides long-term observational data linking wildfires in Yakutia to changes in atmospheric aerosol properties, emphasizing fire effects on AOT variability.

Findings

Wildfires cause significant short-term increases in AOT during summer.

AOT variability correlates with wildfire activity over multiple years.

Fires impact aerosol structure, affecting atmospheric transparency.

Abstract

This paper presents data on the optical thickness AOT in the context of long-term observations, including in times of large-scale forest fires in Yakutia. Sudden changes in such features as the AOT point directly to the impact of fires on aerosol structure of the atmosphere during the summer.
