Contribution of residential wood combustion to hourly winter aerosol in Northern Sweden determined by positive matrix factorization
International audience The combined effect of residential wood combustion (RWC) emissions with stable atmospheric conditions, which is a frequent occurrence in Northern Sweden during wintertime, can deteriorate the air quality even in small towns. To estimate the contribution of RWC to the total atm...
