Here, we use canopy-scale measurements of isoprene fluxes from two tropical ecosystems in Malaysia--a rainforest and an oil palm plantation--and three models of atmospheric chemistry to explore the effects of isoprene fluxes on ground-level ozone. We show that isoprene emissions in these ...
Ground-Level Ozone and Regional Transport of Air Pollutants Air pollutants crossing the Canada-US international boundary from the northeastern Midwest were also found to be important factors for high O/sub 3/ ... YS Chung - 《Journal of Applied Meteorology》 被引量: 894发表: 1977年 Ground-...
Learn more about how ozone can be beneficial up high in the stratosphere but harmful at ground level. For more information about ground-level ozone: AirNow: Current ground level ozone levels where you live Health and Environment- Effects of ground-level ozone pollution. ...
What are the dangers associated with a hole in the ozone layer? What chemicals are being blamed for damaging the ozone layer? What gas causes ground-level ozone? How does ground-level ozone affect the environment? What are three negative health effects of ground-level ozone?
Elevated ground-level ozone, a result of human activity, is known to reduce plant productivity, but its influence on tropical forests remains unclear. Here we estimate how increased ozone exposure has affected tropical-forest productivity and the global carbon cycle. We experimentally measure the ozon...
level ozone formation occurs in the presence of sunlight, typically the ultraviolet (UV) spectrum, when nitrogen oxides (NOx), carbon monoxide (CO), non-methane hydrocarbons (NmHCs), methane (CH4), and volatile organic compounds (VOCs) react in the atmosphere. These are referred to as ozone ...
In addition, rising air temperatures will increase levels of important air pollutants, such as ground-level ozone, particularly in areas that are already polluted 此外,特别是在已被污染地区,气温升高将增加诸如地表臭氧等主要空气污染物的浓度。 UN term 对流层臭氧 UN term Show algorithmically gene...
we elucidate the spatiotemporal and seasonal variability of ground-level ozone (O3) in Malaysia using backward trajectory and Generative Additive Model. Concentrations of O3and other air pollutants (NO2, CO, SO2and PM2.5) from a total of 43 air quality stations across the country from 2107 to...
This report provides a synthesis of current knowledge on the effects of ground-level ozone on ecosystem services and biodiversity. Ecosystems provide an array of services upon which humans depend for food, fresh water, climate regulation... G Mills,S Wagg,H Harmens 被引量: 36发表: 2013年 Buil...
Such mathematical models could specify the amount of ozone that stems from human activity, detail its global circulation, and help scientists predict the possible effects of groundlevel ozone on climate and agriculture, Logan notes. Atlantic winds transport ozone eastward Sanchez is out for a month ...
