Abstract Tropical stratospheric aerosol injections are known to strengthen the wintertime Stratospheric Polar Vortex (SPV). Here, we revisit the circulation response to aerosol perturbations during the first month following injection using chemistry‐climate model simulations of regional nuclear war scenarios.

Physicochemical characterization of combustion generated inorganic nanoparticles
Combustion generated particulate matter is widely recognized to be the major pollutant in urban areas because of stationary combustor and vehicular traffic sources. Particularly the ultrafine fraction was proven to have the highest impact on human health

Interaction of Ladle Slag With Varying SiO2 Content and Recyclate‐Based MgO–C Refractories
Ladle slags (CaO/Al2O3 = 1) with 1–20 wt% SiO2 were investigated in contact with industrial MgO–C refractories fabricated from fresh magnesia and 50 wt% recyclate. The sessile drop method at 1600°C reveals intensive gas formation, delayed slag infiltration in recyclate‐based samples, and, under high‐SiO2 slag, formation of a dense MgAl2O4‐rich ...

Black Carbon Aerosol Size in Wild‐, Prescribed‐, and Agricultural‐Fire Smoke
Abstract Refractory black carbon (rBC), a primary aerosol material, is radiatively significant and a uniquely useful tracer of aerosol processes. Here we present analyses of open‐burning generated rBC size distributions observed both from a research aircraft and from ground‐based sampling.

THERMAL RADIATION OF SPHERICAL AND CYLINDRICAL SOOT PARTICLES [PDF]
The effect of soot shape on soot radiation from flame and smoke is considered in the present study. It is realized that soot particles generally conglomerate into different shapes. while the limiting bounds are being either spherical or long chains.

Size Distribution and Structure of Wall-Deposited Soot Particles in an Automotive-Size Diesel Engine
Wall-deposition of soot particles occurs during the cylinder liner wall/flame interaction, which can potentially deteriorate engine oil quality and alter the heat loss rate in a diesel engine.

Light Absorbing Particles Are Retained in Snow During Springtime Snowmelt in the Sierra Nevada, CA
Abstract Light absorbing impurities, such as black carbon (BC) and mineral dust (MD) particles, are important constituents of seasonal snowpacks, especially when they are present near the surface where they can influence snow albedo and energy balance.
