Sentences with phrase «surface ozone»

I wonder could that have allowed a great deal of extra incoming UV - B to warm surface ozone (both man - made and natural) lending to increased surface temperatures?

That's one conclusion from a new health assessment based on the Tropospheric Ozone Assessment Report or TOAR, an effort by the International Global Atmospheric Chemistry Project to create the world's most comprehensive database of surface ozone observations from all available ozone monitoring stations around the globe.

A 2006 study in the journal Atmospheric Chemistry and Physics found that an increase in shipping could cause surface ozone levels to double or triple in the summer time, compared with the early 2000s.

Figure 3: Percentage difference in monthly mean surface ozone concentrations in March, between the run in which spring and summer sea ice is removed («extreme scenario») and the run in which no perturbations were applied.

The goal of this paper, TOAR - Health, is to present the global distribution and trends of ozone using all available surface ozone observations and relying on ozone metrics that are relevant to human health.

«We created the largest database of surface ozone from hourly observations at more than 4,800 monitoring sites worldwide, and we're making these data freely available to anyone who wants to investigate the impact of ozone on human health, vegetation, and climate.»

The TOAR database of surface ozone metrics is now publicly available and can be used by scientists and policymakers around the world to quantify the impacts of ozone on human health and vegetation.

Methane, which is increasing in the atmosphere, contributes to increased ozone globally and will enhance baseline levels of surface ozone across the United States.

Consistency for surface ozone levels was more difficult to achieve due to the influence of emissions from up - wind regions.

The point being that w / out ongoing decimation from soot, wind, ozone (surface ozone pollution that warms from UV), the AO and greenhouse gases, the ice would have been more likely to recover from the impact of such an event.

Impact: Replacing old ozone analyzers at existing stations and adding new sites on the west and east coast of the U.S. would increase the reliability and scope of surface ozone measurements (which may be impacted by industrial activity in Asia).

Research led by the Universities of Leicester and Edinburgh and 12 other research institutions show where surface ozone levels are important for human health.

All data have undergone quality control and validation by the air quality agencies that collected the data (TOAR - Surface Ozone Database).

Emissions from vehicles, power plants, industrial operations, and other human activities are a primary cause of surface ozone, which is one of six main pollutants regulated in the U.S. by the Clean Air Act.

These ozone health metrics are derived based on of clinical and epidemiological studies that examine health outcomes associated with short - and long - term exposure of surface ozone that are typically based on daily maximum 8 - hour running mean ozone (MDA8) mixing ratios.

The springtime stratospheric ozone hole & surface ozone also have an impact, and the combination of soot & surface ozone would exceed the impact from greenhouse gases (soot deposition alone is on par with greenhouse gases in the boreal thaw).

Again, no mention of soot or surface ozone.

Hotter summers and more frequent fires will lead to more cases of heat stroke and deaths, and to higher levels of near - surface ozone and smoke, which would cause more «code red» air quality days.

We have developed the Integrated Climate and Air Quality Modeling System (ICAMS) through the one - way nesting of global — regional models to examine the changes in the surface ozone...

Exposure to surface ozone has detrimental impacts on vegetation and crop yields.
