Springtime ozone distributions for 1984, 1995–2008 in the mid-troposphere (3.0–8.0 Springtime ozone levels above western North America are rising primarily due to air flowing eastward from the Pacific Ocean, a trend that is largest when the air originates in Asia. The US EPA recently proposed new tougher ground-level ozone standards.
The two combine in the atmosphere to make either nitric acid or peroxynitrous acid; the so-called branching ratio of these two chemicals is important in models of ozone production. This means less of the hydroxyl radical and nitrogen dioxide go away, leading to proportionately more ozone, mostly in polluted areas, Okumura said.
solar, wind, hydroelectric, and nuclear) as compared to the eastern US (EUS), where the electricity market is dominated by pollutant and precursor emitting combustion sources (i.e., coal, oil, natural gas, and biomass). Across scenarios, we found the more cars that transitioned to electric power, the better for summertime ozone levels.
The California Air Resources Board’s latest state inventory of greenhouse gas emissions shows that California’s GHG emissions continue to decrease. In-State Hydro, Solar, and Wind Electricity Generation.
However, emissions do not just remain in conurbations; particles and gaseous pollutants can be transported thousands of kilometers by the wind. The transport and transformation of plumes from selected European and Asian major population centers (MPCs) will now be investigated with special focus on the rate of formation of ozone and aerosols.
The committee that wrote the report focused on monetizing the damage of major air pollutants—sulfur dioxide, nitrogen oxides, ozone, and particulate matter—on human health, grain crops and timber yields, buildings, and recreation. Most vehicle and fuel combinations had similar levels of greenhouse gas emissions in 2005.
Concentrations of carbon dioxide in the atmosphere surged at a record-breaking speed in 2016 to the highest level in 800,000 years, according to the World Meteorological Organization’s Greenhouse Gas Bulletin. Concentrations of CO 2 are now 145% of pre-industrial (before 1750) levels, according to the Greenhouse Gas Bulletin.
will partner with LLNL and ANL to increase the efficiency and reduce start-up times of gas turbine combustors in a project titled “Ultra-Clean Transient Turbine Combustor”. Project will be co-funded by the Building Technologies Office and the Advanced Manufacturing Office. VAST Power Systems, Inc.
In addition, other studies have shown that increases in PM 2.5 , NO 2 , and ozone were associated with lower test scores that were “equivalent to the effects of short-term reductions of thousands of dollars in district median household income.”
The bill also modifies the Clean Air Act to require the development of greenhouse gas emissions standards for all other mobile sources—e.g., Within three years of enactment, the EPA would need to determine the lifecycle greenhouse gas emissions of all transportation fuels and determine the fuel emission baseline.
This SAE spec would make it so you could go to a gas station and they would have the proper voltage and plug for your car. Neutral Kaitou KID @ Apr 19th 2009 4:45PM not if the electricity is from ultra efficient solar panels, hydroelectric dams or wind. Or Cell phone companies agreeing on all cellphone using a mini-usb plug.
This proposal reduces emissions contributing to fine particle (PM 2.5 ) and ozone nonattainment that often travel across state lines. SO 2 and NO x react in the atmosphere to form fine particle pollution and ground-level ozone (smog), which are linked to widespread illnesses and premature deaths. NO x emissions would drop by 52%.
According to Forbes , studies have found that solar and wind power is often cheaper than power from fossil fuels, even without financial assistance, and their daily operations undercut even the most cost-effective coal plants. than gas-fueled vehicles. . It uses the power of wind pushing turbines to collect energy.
Depletion of Antarctic ozone is a more important factor than increasing greenhouse gases in shifting the Southern Hemisphere jet stream in a southward direction, according to researchers at Penn State. Understanding the differences between these two forcings is important in predicting what will happen as the ozone hole recovers.
