Regional Contrasts in Dust Emission Responses to Climate
Time-series analysis of Earth’s major dust source regions reveals common traits in responses of wind erosion to climate anomalies. Lag crosscorrelations of monthly mean aerosol optical depth, precipitation, vegetation, and wind speed are examined from 1979–1993. The response to monthly climate anomalies can differ greatly from the response to seasonal mean climate. The signs, magnitudes, and la...

متن کاملEmission metrics for quantifying regional climate impacts of aviation
This study examines the impacts of emissions from aviation in six source regions on global and regional temperatures. We consider the NOx-induced impacts on ozone and methane, aerosols and contrailcirrus formation and calculate the global and regional emission metrics global warming potential (GWP), global temperature change potential (GTP) and absolute regional temperature change potential (AR...
متن کاملResponses in Plants Exposed to Dust Pollution
Dust particles form a major part of air pollutants arising due to industrial processes and pose serious threat to the ecosystem. In India 30-35% of air pollutants comprises of dust particles. Activities such as coal mining, quarrying, stone crushing, thermal power plants, cement industries etc., adds huge quantities of dust to the environment. The current scenario of large scale deforestation; ...
متن کاملDust Emission Features in NGC
We present 0.35 to 2.5 μm spectra of the south and northwest filaments in the reflection nebula NGC 7023. These spectra were used to test the theory of Seahra & Duley that carbon nanoparticles are responsible for Extended Red Emission (ERE). Our spectra fail to show their predicted second emission band at 1.0 μm even though both filaments exhibit strong emission in the familiar 0.7 μm ERE band....
