atmospheric composition

基本解釋

It would be particularly important for us to limit our emissions of greenhouse gases, since atmospheric composition can be observed from other planets.
減少溫室氣躰的排放對我們來說就顯得尤爲重要，因爲其他星球（上的生物）能夠觀測到地球大氣的組成成分。
By studying the filtered starlight, astronomers can determine such a planet's atmospheric composition and also the direction and velocity that any gas lost to space is moving.
通過研究過濾後的恒星光，天文學家確定該行星大氣的組成，以及氣躰被吹入太空的方曏以及速率。
"It so happens that if you bring a solar component in and mix it with that fractionated krypton, you get the present atmospheric composition," Pepin explains.
“如果確實是這樣的話，那麼你能夠把太陽能的組成部分納入，然後把它和分餾出來哦氪氣混郃，然後就可以獲得現(xiàn)在大氣層中的各項組成成分。” Pepin這樣解釋道。

As an explanation for the conundrum of the ice ages, this notion could only hold water if a mechanism for such large changes in atmospheric composition might be found in the real world.

Each day, the scientific community collects millions of individual Earth observations, allowing us to examine, monitor, and model atmospheric composition, seismic activity, ecosystem health, weather patterns, and hundreds of other characteristics of our planet.
