Fine particles in the air produced by road transport trap more radiation in the earth's atmosphere than previously estimated, and therefore may contribute more to global warming than realised, according to new research. In contrast, the impact of particles from shipping appears to reflect more radiation than previously thought, whilst the effect of particles from aviation is comparatively small.

Although there have been significant advances in the understanding and monitoring of atmospheric processes in the last decade, a recent study suggests that uncertainties in their assessment continue to grow and more complex studies are required to understand the precise relationship between atmospheric chemicals, such as air pollutants, and climate change.

Using hydrogen as an energy carrier can help reduce air pollution and greenhouse gas (GHG) emissions associated with fossil fuels, according to recent research. However, if used on a large-scale, it is important that hydrogen does not leak significantly into the atmosphere as it might have some negative environmental effects, such as increasing the lifetime of methane, increasing climate effects and causing some depletion of the ozone layer.

Planting trees in urban areas has been recognised as a cost-effective means of reducing air pollution for several major cities worldwide. In a new study, the impact of tree species diversity on levels of ozone pollution in Rome was assessed. The results suggest that different species of tree complement each other in providing this important ecosystem service.

Levels of air pollution significantly increase on the island of Svalbard in the Norwegian Arctic when tourist cruise ships are present, according to a recent study. With shipping levels rising in the region, the researchers recommend that stricter emissions regulations are introduced in order to limit the impact of pollution on the Arctic environment.

Four ozone-depleting gases, previously undetected in the atmosphere, have been found by new research. The work suggests that more than 74 000 tonnes of these human-made substances have been released since 1978, and that two are continuing to accumulate in the atmosphere. However, it is not yet known where they come from.

Nitrous oxide (N₂O) is a potent greenhouse gas and atmospheric pollutant. A new study proposes tackling both problems by removing N₂O from the atmosphere using a combination of two innovative technologies — photocatalytic breakdown of the N₂O to nitrogen and oxygen, and this within a solar chimney power plant that generates renewable electricity. Although some way off from commercial development, the researchers say this approach is feasible, and they outline how these two technologies can be integrated to reduce the climate impact and polluting effects of N₂O emissions.

It is important to understand the extent to which atmospheric (air) pollution damages plants (i.e. its phytotoxicity) as well as the wider ecosystem (i.e. its ecotoxicity). For this reason, researchers have adapted the Organisation for Economic Cooperation and Development (OECD) Vegetative Vigour Test1 for the assessment of the ecotoxicity of samples of aerosol (suspensions of fine solid particles or liquid droplets in air). Typically, the test involves spraying the trial liquid on above-ground portions of the plant, such as the leaves. The adapted protocol involves extracting water-soluble aerosol compounds from aerosol samples to spray on the plant. The new protocol is sensitive enough to determine phytotoxicity and establish a clear cause–effect relationship, and as such has the potential to serve as a useful tool for the assessment of the effects of air pollution on environmental and human health.

A modeling framework for evaluating the impact of weather conditions on farming and harvest operations applies real-time, field-level weather data and forecasts of meteorological and climatological conditions together with user-provided and/or observed feedback of a present state of a harvest-related condition to agronomic models and to generate a plurality of harvest advisory outputs for precision agriculture. A harvest advisory model simulates and predicts the impacts of this weather information and user-provided and/or observed feedback in one or more physical, empirical, or artificial intelligence models of precision agriculture to analyze crops, plants, soils, and resulting agricultural commodities, and provides harvest advisory outputs to a diagnostic support tool for users to enhance farming and harvest decision-making, whether by providing pre-, post-, or in situ-harvest operations and crop analyzes.

Combinations of atmosphere control members are used to control the atmosphere within a sealed container which contains a respiring biological material. The combination makes use of a first ACM having a first R ratio (the ratio of carbon dioxide permeability to oxygen permeability) and a second ACM having a second R ratio, the first R ratio being substantially greater than 1.0, and the second R ratio being less than the first R ratio. This combination (31, 321, 322, 331, 332) can form part of the sealed container (1) itself, or can be part of an assembly (31, 32, 34) through which the packaging atmosphere within the sealed container (1) is circulated.

A PV panel uses an array of small silicon sphere diodes (10-300 microns in diameter) connected in parallel. The spheres are embedded in an uncured aluminum-containing layer, and the aluminum-containing layer is heated to anneal the aluminum-containing layer as well as p-dope the bottom surface of the spheres. A phosphorus-containing layer is deposited over the spheres to dope the top surface n-type, forming a pn junction. The phosphorus layer is then removed. A conductor is deposited to contact the top surface. Alternatively, the spheres are deposited with a p-type core and an n-type outer shell. After deposition, the top surface is etched to expose the core. A first conductor layer contacts the bottom surface, and a second conductor layer contacts the exposed core. A liquid lens material is deposited over the rounded top surface of the spheres and cured to provide conformal lenses designed to increase the PV panel efficiency.

A pressure-stable cylinder/piston unit which blocks water vapor and oxygen and is designed for a needle-free injector, with a chamber arranged in a cylinder, which blocks water vapor and oxygen, and designed for long-term and sterile storage of an injection solution, an end wall with at least one nozzle bore or one outlet element, a pressure-stable outer cylinder, and a pressure-stable piston arranged movably in the chamber and blocking water vapor and oxygen. Methods for bubble-free, automatic or manual filling of the cylinder/piston unit, also at atmospheric pressure are also disclosed.

An inflatable dummy target comprising a chassis of inflatable ducts wrapped with a sheet. The chassis of inflatable ducts can include one or more ring shaped ducts and one or more elongate ducts. The chassis can include at least two ring shaped ducts interconnected by one or more elongate ducts. The dummy target can include several attached axi-symmetrical sections, each section have a chassis of inflatable ducts. Each section can be conical, frustoconical or cylindrical, thereby achieving a concave or convex dummy target geometry.

Sean “Slug” Daley of Atmosphere is a proud son of Minneapolis whose devotion to that city shines through not only in his music, but also in the label he co-founded in large part to help bring shine to his city’s scene, Rhymesayers.

Atmosphere started when Daley was in high school (see above), but the group really started making waves in the early 2000s, with the release of music that would be collected on the album Lucy Ford: The Atmosphere EPs.

The introspective, personal songs on Lucy Ford and follow-up projects like God Loves Ugly and Seven’s Travels struck a chord with a huge audience, and Atmosphere’s constant touring, of a kind much more akin to rock bands than rap acts, helped the group’s following grow to a point where they received airplay on MTV2, performed at large festivals, and received serious attention from big record labels. Rhymesayers, meanwhile, released well-regarded projects from the likes of Brother Ali, Eyedea and Abilities, Blueprint, MF DOOM, and many others.

Atmosphere’s latest album, released this past August, is Fishing Blues.

One of the most fascinating things about planet Earth is the way that life shapes the Earth and the Earth shapes life.
