The stratosphere is the stable (stratified) layer of atmosphere extending from the tropopause upward to a height of about 50 km (Fig. The stratosphere is highly stable because the air temperature increases with height up to the stratopause, which is the height of the temperature :// G.

Speight, in Environmental Organic Chemistry for Engineers, The Troposphere. The troposphere is the lowest layer of atmosphere of the Earth and the layers to which changes can greatly influence the floral and faunal environments. Atmosphere of the Earth: it extends from Earth's surface to an average height of approximately 12 km although this altitude actually varies Only trace amounts of helium, carbon dioxide, oxygen, and other gases are present.

Many weather satellites orbit Earth in the exosphere. The lower part of the exosphere includes low-Earth orbit, while medium-Earth orbit is higher in the atmosphere. The upper boundary of the exosphere is visible in satellite images of ://   CHLOROFLUOROCARBONS Chlorofluorocarbons (CFCs) are a class of chemicals that contain only atoms of carbon, chlorine, and fluorine.

As a group, they are unreactive, stable, and poorly soluble in water. Commercially, the most important CFCs were derivatives of methane and :// /chemistry/compounds-and-elements/chlorofluorocarbons. weather, state of the atmosphere at a given time and place with regard to temperature, air pressure (see barometer barometer, instrument for measuring atmospheric pressure.

The character of the snow surface after a snowfall depends on the original form of the crystals and on the weather conditions present when the snow fell. For example, when a snowfall is accompanied by strong winds, the snow crystals are broken into smaller fragments that can become more densely :// Some present research activities are summarized below.

The research interest that underlies my research is the physics of the upper ocean and feedbacks with the atmosphere. Of particular interest are low frequency, large scale phenomena, and the role of the upper ocean as a conduit between the interior ocean and the   CHAPTER STRATOSPHERIC OZONE.

The stratospheric ozone layer, centered at about 20 km above the surface of the Earth (Figure ), protects life on Earth by absorbing UV radiation from the this chapter we examine the mechanisms controlling the abundance of ozone in the stratosphere and the effect of human   See Present-day global budget of CO gives a global budget of CO for the present-day atmosphere.

Fossil fuel combustion and biomass burning (principally associated with tropical agriculture) are large anthropogenic sources, and oxidation of CH4 is another major source (See Sources of CO).Most of the CO in the present-day troposphere is anthropogenic.

The main sink of CO is CESM Project. The CESM project is supported primarily by the National Science Foundation (NSF).Administration of the CESM is maintained by the Climate and Global Dynamics Laboratory (CGD) at the National Center for Atmospheric Research (NCAR).; CESM is a fully-coupled, community, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and Wind velocities in the atmosphere are measured in terms of a local Cartesian coordinate system inscribed on a sphere.

Although ozone is present in small concentrations throughout the atmosphere, most (around 90%) exists in the stratosphere, a layer 10 to 50 kilometres above the Earth’s :// The atmosphere surrounds Earth and protects us by blocking out dangerous rays from the sun.

The atmosphere is a mixture of gases that becomes thinner until it gradually reaches space. It is composed of Nitrogen (78%), Oxygen (21%), and other gases (1%). Oxygen is essential to   From this point of view, this book actually devotes too little space to history.

Also, the state of the atmosphere in close proximity to the Earth's surface and its importance to the environmental conditions experienced by fuels are discussed.
