Abstract. Remote-sensing (RS)-based estimates of Arctic dust are oftentimes overestimated due to a failure in separating out the contribution from that spatially homogeneous clouds or low-altitude cloud-like plumes. A variety illustrations given with particular emphasis on questionable claims using brightness temperature differences (BTDs) as signature indicator transported mid-latitude deserts generated by local sources. While there is little dispute about presence both Asian and across...
We investigated the climatological-scale, monthly binned, seasonal variation of AERONET/Dubovik retrievals across six stations in North American and European Arctic (multiyear sampling periods ranging from 8 to 17 years). A robust, spring-to-summer (StoS) increase radius peak fine mode (FM) component particle size distribution (PSD) was observed for five stations. The FM aerosol optical depth (AOD) effective at individual showed, respectively, a negligible moderate StoS decrease significant...
The Nile Delta major cities, particularly Cairo, experienced stagnant air pollution episodes, known as Black Cloud, every year over the past decade during autumn. Low-elevated thermal inversion layers play a crucial role in intensifying impacts. Carbon monoxide, ozone, atmospheric temperature, water vapor, and methane measurements from tropospheric emission spectrometer (TES) on board Aura have been used to assess dominant component below layer. In this study, time series analysis,...

Abstract. The suggestion of Huang et al. (2015) on the climatological-scale transport Asian dust to Arctic appears be an important and worthwhile assertion. It is unfortunate that authors undermined, a certain degree, quality assertion by misinterpretation critical 24 March 2010 event (which was chosen illustrate their generalized, claim). They attempted characterize key using AERONET/AEROCAN retrievals taken day later misinterpreted those largely cloud-dominated as being...
