Abstract
Aerosols play an important role in the extreme events of air pollution and climate change. Despite the decade’s efforts, air pollution models are still unable to simulate the heavy pollution events very well due to the complicated aerosol chemical composition, size distribution and spatial and temporal variations. Recently, the aerosol mass spectrometer (AMS) was deployed in Dublin to determine the chemical composition and concentration of submicron aerosols at high temporal resolution. The organic aerosol (OA) was found to dominate the aerosol composition (>50 %) in the heavy pollution events. The particular matter concentration (PM1) was measured to exceed 200 μg m-3 on 19 November 2016 and 22 January 2017.

The tiny particles play an important role in the air pollution and climate change
Evidence is accumulating that emissions of carbonaceous aerosols from residential solid fuel burning in the UK have been underestimated and/or spatially misclassified [15]
Our results show that current emission inventory including EMEP, TNO and NAEI largely underestimate the organic aerosol emissions from residential solid fuel burning
Summary
The tiny particles (particular matter or aerosols) play an important role in the air pollution and climate change. It is of great interest to examine the carbonaceous aerosols simulations from global and regional air quality models by space-based or groundbased measurements. Evidence is accumulating that emissions of carbonaceous aerosols from residential solid fuel burning in the UK have been underestimated and/or spatially misclassified [15].
