Outline of Final Research Achievements

Aerosol deposition caused by wildfire has important roles on nutrient cycle at boreal forest. Increment of wildfire in relation to global warming might enhance the growth and C-budget at boreal forests. We revealed the wildfire effect by dry-deposition observation and model improves.
Observations were held at flux tower at UAF’s campus with multi-layer filtering system. Filter sampling was conducted in 2014 season and the chemical analyses and trajectory analysis by satellite data were examined in 2015. Deposition of trace element increased when wildfire-smoke reached the site, and it is too low concentration of aerosol to reveal regular depositions regularly.
