DustSCAN: A Five Year (2018-2022) Hourly Dataset of Dust Plumes …
2024年6月8日 · DustSCAN includes 9950 discrete plumes over 2018-2022 across the Sahara, the Arabian Desert, and Western and Central Asia. It complements existing resources and provides a framework for detailed...
Saharan dust plumes are a crucial part of Earth's biology and …
2020年6月30日 · The Saharan dust plume is a supersized version of ones that cross the Atlantic all the time, ferrying particles that irritate lungs but also fertilize plant and ocean life.
Dust Source Areas and Their Plume Extent Derived From Satellite …
2024年8月23日 · Identifying where dust comes from and where it goes is essential for understanding how it affects the climate. To do so, we employ high temporal frequency satellite data to backtrack dust plumes to their sources, revealing key dust-emitting regions and their seasonal variations.
Comparison of the polluted dust plume and natural dust air mass …
2024年7月10日 · As cold air moved southward southeasterly, the cold front at the bottom of the high-pressure system strengthens. As they arrived in eastern and southeastern China, the dust plumes met polluted air masses. Thus, the polluted dust occurred. By comparison, the cold front of the Mongolian cyclone is formed by entering the warm zone in S2.

On June 18, 2020, NASA-NOAA’s Suomi NPP satellite imaged a large light brown plume of Saharan dust over the North Atlantic Ocean. On a typical year, hundreds of millions of tons of dust cross the Atlantic Ocean from Africa.
A 14‐Year Climatology of Saharan Dust Emission Mechanisms …
2019年8月8日 · A novel method is developed to identify emission mechanisms from automatically tracked dust plumes in the central and western Sahara; Dust plumes across 14 summers are tracked individually and classified probabilistically as low-level jet or cold pool outflow events
ACP - Record-breaking dust loading during two mega dust storm …
2022年6月17日 · During the 3.15 and 3.27 events, the invasion of dust plumes greatly degraded the visibility over large areas of NC, with extreme low visibility of 50 and 500 m recorded at most sites on 15 and 28 March, respectively.
Comparison of the polluted dust plume and natural dust air mass …
2024年7月10日 · In this study, we illustrate the spatial distribution, the transport path of the dust and its influence on the air quality of downstream cities utilizing ground-based and space-borne measurements. Results indicate a more complicated pollution, coexisting of polluted dust stage S1 and pure dust stage S2.
Sulfate and nitrate elevation in reverse-transport dust plumes …
2023年2月15日 · Dust reverse-transport (DRT) events can occur in eastern China when dust plumes undergo a distinct turn caused by Asian highs or cyclones, resulting in the re-appearance of the dust plume in one place but with anthropogenic pollutants mixed in. In this study, three DRT events were identified at a coastal city, Qingdao.
Investigation of June 2020 giant Saharan dust storm using remote ...
2022年4月12日 · This paper investigates the characteristics and impact of a major Saharan dust storm during June 14th–19th 2020 on atmospheric radiative and thermodynamics properties over the Atlantic Ocean.
