“…Wind affects TEOM measurements also in Murska Sobota and Nova Gorica. Sharratt and Pi [27] in a controlled experiment (wind tunnel) observed that TEOMs measure higher levels than active samplers when wind speed is high. Even though in Maribor PM 10 is measured with TEOM-FDMS, temperature exhibits a major effect when compared to reference measurements.…”

The reference method for PM 10 and PM 2.5 measurement in Europe is active sampling with subsequent gravimetric analysis. Also tapered element oscillating microbalance (TEOM) monitors are widely used across Europe for the assessment of particulate matter (PM), even though they are known to be biased due to the loss of semi-volatile materials attributed to sample heating. In our work we correct TEOM PM 10 measurements at eight different monitoring sites located in different surroundings and different climates across Slovenia to replicate reference measurements. We use simultaneous reference and TEOM measurements from a period of seven years (2011-2017) and assess the advantage of custom defined correction factors (with linear and orthogonal regression) compared to default correction factors. We further try to improve the corrections by adding meteorological parameters as inputs and training a linear model (lasso) and nonlinear model (random forest). Random forest and lasso models also enable us to evaluate the impact of different meteorological parameters or chemical compounds on TEOM measurements. Our results show that TEOM measurements can be efficiently corrected using correction factors defined with two linear regressions (for summer and winter) at most locations across continental Slovenia. Koper, which lies at the sea side, was the most problematic measurement site. There the measurements were the most affected by the meteorological situation, and they could not be successfully corrected. When examining the effect of the chemical composition at two different locations, levels of NH + 4 , NO − 3 , and organic carbon exhibited major impact on the discrepancies between reference and TEOM measurements.

“…Even if less severe with respect to smaller particle ones, >10-μm particles could have an impact on human being wellness, which investigation can require to go further respect to standard air quality measurements of PM10 and PM2.5 (Reynolds et al 2016). Particular attention should be paid when the PM is measured with instruments based on different methods (i.e., gravimetric and equivalent methods) and take into account the influence that the wind speed could have on the measurements even when using the same type of instrument, especially in conditions of high wind speed (Sharratt and and Pi 2018). Novel XRF spectrometers providing chemical composition of PM in different size classes (Furger et al 2020) could be relevant for improving source apportionment, but are still research systems available in few laboratories.…”

Mineral dust produced by wind erosion of arid and semi-arid surfaces is a major component of atmospheric aerosol that affects climate, weather, ecosystems, and socio-economic sectors such as human health, transportation, solar energy, and air quality. Understanding these effects and ultimately improving the resilience of affected countries requires a reliable, dense, and diverse set of dust observations, fundamental for the development and the provision of skillful dust forecasts tailored products. The last decade has seen a notable improvement of dust observational capabilities in terms of considered parameters, geographical coverage, and delivery times, as well as of tailored products of interest to both the scientific community and the various end-users. Given this progress, here we review the current state of observational capabilities including in-situ, ground-based and satellite remote sensing observations, in Northern Africa, the Middle East and Europe for the provision of dust information considering the needs of various users. We also critically discuss observational gaps and related unresolved questions while providing suggestions for overcoming the current limitations. Our review aims to be a milestone for discussing dust observational gaps at a global level to address the needs of users, from research communities to non-scientific stakeholders.
