The depth of the planetary boundary layer ranges from as little as about 100 metres (330ft) on clear, calm nights to 3,000m (9,800ft) or more during the afternoon in dry regions. Created by world-famous photographer and environmentalist Yann Arthus- Bertrand, every stunning aerial image tells a story about our changing planet.

Arthus-Bertrand's mission was to create a photographic record of the natural world at the start of a new millennium. The authoritative text is written by the widely respected environmentalist Lester Brown and other recognized experts in the fields of ecology, economics, geography and demography. As a national tour, it travelled around the UK over a period of 8 years, visiting cities including Bath, Birmingham, Norwich, Plymouth, Swansea, Oxford, Bristol, Edinburgh, Armagh and More London on the South Bank, London. This weight of the air above is equivalent to the weight from a 1 kg mass pressing down on every square centimetre of your skin!In a large format book, the pictures invite you to study the details and such softness is extremely disappointing. The troposphere is denser than all its overlying layers because a larger atmospheric weight sits on top of the troposphere and causes it to be most severely compressed. The author may have thought that the actual years don't matter, but it would still have been nice to know. In conclusion I will reiterate that with better captions, better print quality and a better layout, this is a much better book than the original "The Earth From The Air". Main article: Mesosphere Afterglow of the troposphere (orange), the stratosphere (blue) and the mesosphere (dark) at which atmospheric entry begins, leaving smoke trails, such as in this case of a spacecraft reentry.

In this newer and smaller book, the print quality has improved remarkably and since shrinking down any photo usually increases sharpness and decreases noise, the photos are actually better looking. The average temperature of the atmosphere at Earth's surface is 14°C (57°F; 287K) [34] or 15°C (59°F; 288K), [35] depending on the reference. The remaining gases are often referred to as trace gases, [12] among which are other greenhouse gases, principally carbon dioxide, methane, nitrous oxide, and ozone. It also aims to shed light on the part of his work never before revealed, a memoire of the time when photography was considered to be a tool for providing information rather than a true artistic medium.Users may opt out of the use of the DART cookie by visiting the Google ad and content network privacy policy. above Earth's surface to the stratopause at an altitude of about 50 to 55km (31 to 34mi; 164,000 to 180,000ft). Meteors begin to glow in this region, though the larger ones may not burn up until they penetrate more deeply. Although the thermosphere has a high proportion of molecules with high energy, it would not feel hot to a human in direct contact, because its density is too low to conduct a significant amount of energy to or from the skin. In the original book, although the photos were larger than life, the print and even original photo quality were mostly mediocre, but sometimes even unacceptably poor.

The mesosphere is the third highest layer of Earth's atmosphere, occupying the region above the stratosphere and below the thermosphere. NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery.NASA’s Commercial Crew Program is delivering on its goal of safe, cost-effective human transportation to and from the International Space Station from the U. The free outdoor exhibition is a spectacular presentation of over 120 large-scale aerial photographs of breathtaking views of our planet taken by world-famous photographer Yann Arthus-Bertrand. Systematic variations in the refractive index can lead to the bending of light rays over long optical paths. This time the captions actually provide some meaningful info about what is in the photo and just gently nudge us to think of various environmental impacts as well. Depending on solar activity, satellites can experience noticeable atmospheric drag at altitudes as high as 700–800km.
