NASA的大气层照片显示大气的层次 蒋迅 老师《从航天器看地球大气层》 http://www.sciencenet.cn/m/user_content.aspx?id=354650 里第一张图片的大图，以及最后一张图。 下载 它们。 可是，从照片还可以清晰地看到大气层的不同层次是怎么看出来的？ 相关：Take a deep breath and then read this http://astrobob.areavoices.com/2010/06/16/take-a-deep-breath-and-then-read-this/ 以下图片无商业用途。 (1) Sunset from the ISS http://www.internet-d.com/?p=9581 Explanation: What are these strange color bands being seen from the International Space Station? The Sun setting through Earths atmosphere. Pictured above, a sunset captured last month by the ISSs Expedition 23 crew shows in vivid detail many layers of the Earths thin atmosphere. Part of the Earth experiencing night crosses the bottom of the image. Above that, appearing in deep orange and yellow, is the Earths troposphere, which contains 80 percent of the atmosphere by mass and almost all of the clouds in the sky. Above the troposphere, seen as a light blue band with white clouds, is the stratosphere, part of the Earths atmosphere where airplanes fly and some hardy bacteria float. Above the stratosphere, visible as a darker blue bands, are higher and thinner atmospheric levels that gradually fade away into the cold dark vacuum of outer space. Sunset is not an uncommon sight for occupants of the International Space Station, because it can be seen as many as 16 times a day.
