[:ja]ジャック・フィッシャー宇宙飛行士がISSから撮影した月です。地球に目を向けると、雲の低さがわかります。ISSは高度400kmの軌道ですが、巻雲や積乱雲はせいぜい10km強ですから、40分の1程度です。
また、対流圏は10~13km程度、成層圏が50km程度まであるので、画像からもなんとなくわかりますが、大気の厚さの方があることがわかります。

[Earthview Wonders] No.271: Moon over Earth
Asronaut captured from ISS the moon over the Earth. The low altitude of clouds is notable seen from ISS. ISS’ orbit is approximately 400km while cirrus clouds rise up to 10-13km at the highest (one fortieth).
As can be recognized from the image, the thickness of the atmosphere is clear, with troposphere up to 10-13km and stratosphere up to 50km at the highest.
