DRONE FOR MEASURING DATA REPRESENTATIVE OF THE CONTENT OF AT LEAST TWO GASES PRESENT IN THE ATMOSPHERE AWAY FROM THE GROUND AND ASSOCIATED MEASUREMENT METHODSaid drone (10) comprises a sensor (40) for measuring representative data, comprising at least one measuring cell open to the atmosphere, at...
aWe cannot say definitely that the temperature rises are due to the greenhouse effect , which is a phenomenon created by the heat energy radiated by the sun and greenhouse gases normally present in the atmosphere 我们不可能确定地说温度上升归结于温室效应,是热能创造的现象放热由太阳和温室气体通常当前...
Past, Present and Future Levels of Greenhouse Gases in the Atmosphere and Model Projections of Related Climatic Changes 来自 Semantic Scholar 喜欢 0 阅读量: 32 作者: E Roeckner 摘要: Ice core analyses of polar ice reveal a high correlation between climatic change and variations in the ...
If so, we may contemplate a heated primitive earth surrounded by a tenuous atmosphere consisting largely of the rare gases as at present represented, with the possible exception of helium. The greater part of the atmosphere, the water, and perhaps the helium, would have been emitted from the ...
aEven if all greenhouse gas emissions were eliminated today, the concentration of gases already in the atmosphere is high enough to produce the global warming effects we are now experiencing and will continue to experience for years to come. 即使今天消灭了所有导致温室效应的气体,气体的集中已经在大...
The Gases of the Atmosphere.~ BY DR. H. F. KELLER, Member of the Institute. (Concluded f r o m vol. cliii, p. 430.) The atomic theory of Dalton, which had just been an- nounced to the scientific world, moreover, required that the elements contained in a compound should be in...
Atmospheric gases hold in suspension great quantities of dust, pollen, smoke and other impurities which are always present in considerable, but variable amounts.The atmosphere has no definite upper limits but gradually thins until it becomes imperceptible. Until recently it was assumed that the air ...

In contrast, the three industrial fluorinated gases –hydrofluorocarbons (HFC),perfluorocarbons (PFC)andsulphur hexafluoride (SF6)– are solely man-made during industrial processes and do not occur in nature. Though they are present in very small concentrations in the atmosphere, they trap heat ve...
Venus - Atmosphere, Greenhouse, Gases: Venus has the most massive atmosphere of the terrestrial planets, which include Mercury, Earth, and Mars. Its gaseous envelope is composed of more than 96 percent carbon dioxide and 3.5 percent molecular nitrogen. T
