Atmospheric observations and model simulations of aerosol physical and optical properties, as well as radiative effects, under high and complex absorption regimes are extremely challenging. The availability of measurements with well-assessed and improved accuracy is also fundamental for model constraint and assessment. It is important to test and validate both ground-based and satellite measurement techniques as well as model simulations in “real” atmospheric conditions. This is particularly urgent for “hot-spot” regions, both in Europe and elsewhere in the world (Atmospheric Brown Clouds), where anthropogenic emissions and natural contributions strongly influence the absorbing aerosol components.

Simpler and lower cost sensors for particulate and gaseous air pollution monitoring are now spreading rapidly for non-regulatory applications. The low-cost of these sensors makes them suitable for large scale networks and accessible to the general public. The small size of these sensors also suggests applications such as monitoring by bicycles, pedestrians and even flying drones. These sensors can be the building blocks for a sensor network to map the dynamics of air quality (e.g., probing hot spots of emissions), for evaluating the exposure of air pollutants in personal scale (e.g., mobile monitoring), or improving the temporal and spatial resolution of monitoring information (e.g., vertical or 3D UAV measurements). However at present there are few standards concerning data quality. In view of the rapid pace of developments in sensor technology, the journal Aerosol and Air Quality Research (AAQR) will host a Special Issue (SI) with the theme "Low-cost Air Pollution Sensors". Papers contributed from 10th International Aerosol Conference (IAC 2018) in St. Louis and other papers relevant to low-cost and portable sensors are welcome. All accepted papers will be collected in a single volume as a special issue.
