Ozone (O3) is a constituent of the troposphere (it is also an important constituent of some regions of the stratosphere commonly known as the ozone layer). The troposphere extends from the Earth's surface to between 12 and 20 kilometers above sea level and consists of many layers. Ozone is more concentrated above the mixing layer, or ground layer. Ground-level ozone, though less concentrated than ozone aloft, is more of a problem because of its health effects.
Photochemical and chemical reactions involving it drive many of the chemical processes that occur in the atmosphere by day and by night. At abnormally high concentrations brought about by human activities (largely incomplete combustion of fossil fuels, such as gasoline, diesel, etc.), it is a pollutant, and a constituent of smog. Many highly energetic reactions produce it, ranging from combustion to photocopying. Often laser printers will have a smell of ozone , which in high concentrations is toxic. Ozone is a powerful oxidizing agent readily reacting with other chemical compounds to make many possibly toxic oxides.

This UCARConnect animation explains what ground-level ozone is, how it is created, the harm it can do, why it's most common in summer months, and what people can do to minimize its creation.

Local weather forecast warnings about unhealthy air could become much more common around the country. A recent scientific study by the National Center for Atmospheric Research warns of a whopping 70% increase in the number of days with unhealthy summertime ozone levels by the year 2050.
The Atmosphere, the Ocean and Environmental Change (GG 140) There are two ozone problems in the atmosphere. Tropospheric ozone in the form of photochemical smog is sometimes dangerously high whereas stratospheric ozone concentration is sometimes dangerously low. Photochemical smog is created through chemical reactions between UV radiation from the run and nitrogen oxides that are emitted from automobiles. High concentrations of tropospheric ozone are dangerous because of the damage ozone can cause to a person's airway if it is inhaled. The EPA has specified limits of ozone concentration but several counties in the USA exceed these limits. The primary air pollutants from which ozone is created have a peak concentration twice a day typically, which is associated with rush hour times ...

Talk of Jack Fishman Saint Louis University, USA at the Anthropocene Symposium, Mainz, 2 December 2013. The scientific symposium has been organized by the Max Planck Institute for Chemistry in celebration of the 80th birthday of Paul Crutzen, winner of the Nobel Prize for Chemistry in 1995.

In the first global assessment of the impact of ozone on climate warming, scientists at the NASA Goddard Institute for Space Studies (GISS), New York, evaluated how ozone in the lowest part of the atmosphere (the troposphere) changed temperatures over the past 100 years. Using the best available estimates of global emissions of gases that create ozone, the GISS computer model study reveals how much this single air pollutant and greenhouse gas has contributed to warming in specific regions of the world. Ozone was responsible for one-third to half of the observed warming trend in the Arctic during winter and spring, according to the new research. Ozone is transported from the industrialized countries in the Northern Hemisphere to the Arctic quite efficiently during these seasons. The finding...
A supplemental video from the 2012 review by Elizabeth A. Ainsworth, Craig R. Yendrek, Stephen Sitch, William J. Collins, and Lisa D. Emberson, "The Effects of Tropospheric Ozone on Net Primary Productivity and Implications for Climate Change," from the Annual Review of Plant Biology: http://www.annualreviews.org/doi/abs/10.1146/annurev-arplant-042110-103829 This animation shows surface ozone images from real-time simulations of MOZART-4 available for chemical forecasts. Estimates of surface ozone concentrations are provided at 6 hr time intervals from July 1, 2010 to June 30, 2011. The Model for Ozone and Related chemical Tracers, version 4 (MOZART-4) is a global chemical transport model for the troposphere, driven by offline meteorology, and is fully described in Emmons et al. (2). Thes...
Natalia Nykiel i Auer, na antenie Czwórki, podczas audycji "Podsiadówka" wykonali napisany razem utwór "Ground level". Zachęcamy do śledzenia kolejnych odsłon cyklu Żywy Gig. Następna premiera już w grudniu. Muzyka: Auer Tekst oraz wykonanie: Natalia Nykiel Video: Natasza Kotarska i Sebastian Kurdelski Koncept: Digital Kingdom
(option A) the stake has to be at the highest point the 2x4 must be straight. check the level as you go around in circles making sure there is no gap under the 2x4. I spray water to compact the sand also i bought grass seeds to prevent erosion . after it was level. (option B) set the stake at the at the lowest point and dig out all of the high points, more labor intensive in most cases. drill thru the top 2x4 clearance hole then drill a pilot hole into the 2x4 in ground so it's easier to nail in.I used a landscaping nail

If I had a dollar for every time I came across a wooden deck that was built to close to the ground, I would probably have enough money, for a nice steak dinner. Anyway, this video will provide you with a few things to think about before you build a wood deck near ground level or on top of your soil or landscaping. Ventilation is important and you must have some type of access to remove any debris that can accumulate or cause damage, under your wood deck. If you found this video useful, then you should check out our websites and other videos.

Last night I did the gta 5 flying school missions, and thought I might make a few videos out of them! I hope the tips I give are of use to the people struggling, I want to see all my subscribers on that leader board! If there is any mission you want to see me doing or any tutorials you want me to make then please tell me in the comments. I will have a lot more playtime next week, so I will be catching up on all the videos I haven't been making lately :D Check out my other YouTube channels more GTA V videos: ► Tonksi - http://goo.gl/cd85Iy ► TonksiPlays - http://goo.gl/cirVBh ► OriginalsCrew - http://goo.gl/qhg4V6 Follow me on other social media to follow my GTA 5 Online adventures: ✔ Twitter - http://goo.gl/MSl4iF ✔ Twitch - http://goo.gl/wtGQAE ✔ Reddit - http://goo.gl/ewkucY Join...

It just depends how close to ground level you are
It just depends how close to ground level you are
Can you see the hurt can you see the pain
Can you feel the rain comin' like a train of thought
Yeah ee Yeah
It just depends how close to ground level you are

Whether rain or shine whether yours or mine
Say I won't go blind for no philistine no more

C'mon
We' re sick of seein' poverty
Yeah ee Yeah
We' re sick of seein' misery
We' re sick of the fatality
Yeah ee Yeah
In every locality
Are we just killing time
Waiting for a sign
Like a battle cry
Or a long goodbye no no
It just depends how close to ground level you are

C'mon
They'll use you as artillery
They want you in the military
Ya gott know your enemy
Yeah ee Yeah
But we all know the killer be
They act so viciously
Wearin' pure diguise they camouflage their eyes
All around there's spies no-one realise no no
It just depends how close to ground level you are
So get on train of thought
