Microplastics (MP) have been retrieved from settled dusts and rainfall collected monthly over a period of year daily an additional ten days in the city Shiraz at elevated remote site (Mount Derak) Iran. Total deposition ranged about 1000 to 3500 MP m?2 200 600 Mount Derak, with greater taking place during dry months (June November) than when precipitation events occurred. Overall, was dominated...

Abstract. Trajectory models are intuitive tools for airflow studies. But in general, they limited to non-turbulent, i.e. laminar flow, conditions. Therefore, trajectory not particularly suitable investigating within the turbulent atmospheric boundary layer. To overcome this, a common approach is handling uncertainty as random deviation from mean path order create statistic of possible solutions...

During an exceptionally warm September in 2016, unique and stable weather conditions contributed to a heat wave over Poland, allowing for observations of aerosol optical properties, using a variety of ground-based and satellite remote sensors. The data set collected during 11–16 September 2016 was analysed in terms of aerosol transport (HYbrid Single-Particle Lagrangian Integrated Trajectory mo...

The dust event from 12 January to 17 2021 (“1.12 event”) is the first process in and earliest last two decades. 14 18 March (“3.15 was strongest storm past decade. Distribution, transport, impact on urban air quality of these typical events were studied using multi-source satellite data, a HYSPLIT trajectory model, 3D concentration-weighted model. Results show that both affected wide range area...

The research of atmospheric aerosol in mountain glacier areas has attracted more and people’s attention. For the first time, a field observation study total suspended particles (TSPs) for four seasons from September 2019 to August 2020 was carried out at Tianshan Glaciological Station source area Urumqi River, East Mountains, China. TSPs presented typical seasonal characteristics high autumn lo...

A short-duration but high-impact air quality event occurred on 28 November 2018 along the Rio Grande Valley of New Mexico. This fire outside typical wildfire season, and greatly impacted in Socorro, NM, surroundings. Measurements were taken during using an aerosol light scattering technique (integrating nephelometer) a particulate mass concentration monitor (DustTrak PM optical monitor). The in...

Lidar is a reliable tool for active remote sensing detection of atmospheric aerosols. A multi-wavelength aerosol lidar (MWAL) with 355 nm, 532 and 1064 nm as light sources has been developed deployed operational observations at Haidian District Meteorological Service Beijing. The structure design, specifications, observation campaign, principle the MWAL are introduced. To ensure accuracy reliab...

The work is devoted to the study of climatic effects black carbon (BC) transferred from forest fires Arctic zone. HYSPLIT (The Hybrid Single-Particle Lagrangian Integrated Trajectory model) trajectory model was used initially assess potential for particle transport fires. results analysis 2019 showed that probability transfer particles ranges 1% 10%, and in some cases increases 20%. Detailed st...

Abstract Students from the University of Alabama in Huntsville successfully deployed three micro superpressure balloon satellites winter 2021. planned and implemented all phases project: obtaining funding, determining project timelines, preparing equipment, launching balloons, designing implementing a website, writing daily blogs on progress, analyzing data. The objective flights was to use bal...
