About this deal

The average temperature of the atmosphere at Earth's surface is 14 °C (57 °F; 287 K) [34] or 15 °C (59 °F; 288 K), [35] depending on the reference. Before this time, any oxygen produced by photosynthesis was consumed by the oxidation of reduced materials, notably iron. French aerial photographer Yann Arthus Bertrand spent ten years making a photographic inventory of the earth's surface. Because the thermopause lies at the lower boundary of the exosphere, it is also referred to as the exobase.

Above this altitude lies the heterosphere, which includes the exosphere and most of the thermosphere. A classic of its kind, this book will heighten everyone's awareness of today's urgent ecological issues. Atmospheric circulation is the large-scale movement of air through the troposphere, and the means (with ocean circulation) by which heat is distributed around Earth.Blue light is scattered more than other wavelengths by the gases in the atmosphere, surrounding Earth in a visibly blue layer at the stratosphere, above the clouds of the troposphere, when seen from space on board the ISS at an altitude of 335 km (208 mi) (the Moon is visible as a crescent in the far background). In addition to the images for which the original is renowned, this version includes 100 new photographs and seven new essays by experts on environmental issues. The early basic carbon isotopy ( isotope ratio proportions) strongly suggests conditions similar to the current, and that the fundamental features of the carbon cycle became established as early as 4 billion years ago. It extends from the thermopause (also known as the "exobase") at the top of the thermosphere to a poorly defined boundary with the solar wind and interplanetary medium.

These free-moving particles follow ballistic trajectories and may migrate in and out of the magnetosphere or the solar wind. The influence of life has to be taken into account rather soon in the history of the atmosphere because hints of early life-forms appear as early as 3. In May 2017, glints of light, seen as twinkling from an orbiting satellite a million miles away, were found to be reflected light from ice crystals in the atmosphere. mi; 39,000 ft) above Earth's surface to the stratopause at an altitude of about 50 to 55 km (31 to 34 mi; 164,000 to 180,000 ft). During the day the planetary boundary layer usually is well-mixed, whereas at night it becomes stably stratified with weak or intermittent mixing.The average molecular weight of dry air, which can be used to calculate densities or to convert between mole fraction and mass fraction, is about 28.

Arthus-Bertrand's breathtaking, full-colour photographs are accompanied by informative captions that illuminate what we see, and describe the environmental concerns related to each location. Atmospheric pressure is the total weight of the air above unit area at the point where the pressure is measured.

Animation shows the buildup of tropospheric CO 2 in the Northern Hemisphere with a maximum around May. The geocorona visible in the far ultraviolet (caused by neutral hydrogen) extends to at least 100,000 kilometres (62,000 mi). All-new captions and the addition of authoritative new texts by experts in various environmental fields illuminate Arthus-Bertrand's monumental achievement. His now-recognisable preferences are much in evidence, such as a person or animal to give scale or reference to a shot (the relationship between man and beast greatly informs his more traditional portrait work, such as Dogs and Cats, local markets, primitive enclosures and dwellings, seaweed, water as transport, life-sustainer, destroyer and habitat and an irresistible attraction to the flamingo's brilliant hue.
