When it falls from the sky, it fertilizes ecosystems like the Amazon rainforest, which needs dust to provide key nutrients like phosphorus. Dust also seeds clouds, which scatter sunlight and cool the planet. Dust is naturally emitted into the atmosphere by deserts, and by examining the geological record in ice, for instance, researchers can see how dust has changed throughout eons.
These days, dust is very much affected by human action around the world. Due to irrigation, it is being dried out — and turning into a major dust source. Another word for dust or particulate matter is aerosol try not to think of the stuff that comes out of a spray can, which is entirely different. Dust is one big uncertainty holding back models that help scientists predict climate change. As the largest aerosol by mass, it has major impacts. It both absorbs and scatters sunlight to alternately warm or cool the planet.
In this context, there is a need to examine the effects of dust in our environment and climate through a fresh new perspective, which will help to reduce the large uncertainties in global and regional climate models in regards to current and future climate simulations. This Research Topic calls for papers that can significantly improve our understanding of the global dust cycle by employing remote sensing techniques, in situ observations, lab measurements, reanalysis data, and state-of-art numerical models.
We especially welcome new ideas that help to fill the gap in our current understanding of dust-climate-environment interactions through the integrated use of both observations and numerical modeling. Specifically, this Research Topic seeks to address challenges faced by the dust research community, including but not limited to: 1 Identification of global dust source regions in a fine spatial resolution e. Keywords : Mineral dust, dust cycle, dust-climate coupling, dust-radiation interactions, dust-cloud-rainfall interactions, health impacts, dust effect on environment and life remote sensing of atmospheric aerosols, spatiotemporal variability of atmospheric dust.
Important Note : All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review. With their unique mixes of varied contributions from Original Research to Review Articles, Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!
