Trace gases play a major role in controlling radiation exchanges in the atmosphere and consequently in determining the atmospheric circulation and, to a large extent, the climatic conditions at the Earth's surface. Coupling between the lower, the middle and the upper atmosphere, as well as ...
Hydrogen radicals are produced in the martian atmosphere by the photolysis of water vapour and subsequently initiate catalytic cycles that recycle carbon dioxide from its photolysis product carbon monoxide. These processes provide a qualitative explanation for the stability of the atmosphere of Mars, which...
Ever since the discovery of the ozone hole over the Antarctic and the recognition of the damaging effects of acid rain, the role of atmospheric aerosol particles in determining the chemical balance of the atmosphere has received much attention. Aerosol particles produced in combustion can also have...
Reactions of Mg-rich silicates with calcium carbonates/sulfates result in the formation of materials that could potentially be used for low-cost carbon dioxide removal from the atmosphere. Yuxuan Chen & Matthew W. Kanan Article | 12 February 2025 σ-Bond insertion reactions of two strained di...
Chemical kinetics relates to how quickly a medicine works in the body, towhether the processes that form and deplete ozone in the atmosphere are in balance,and to such industrial challenges as the development of new catalysts, materials thatspeed up reactions.Our goal in this chapter is to ...
Rising levels of carbon dioxide in the atmosphere are a major cause of climate change and now a new study has confirmed that atmospheric CO 2 is also affecting the ocean chemistry and potentially harming sea life. Montana State
First observation of micrometeoroid differential ablation in the atmosphere [1]Every day, billions of microgram-sized-extraterrestrial particles enter and ablate in the upper layers of the Earth's atmosphere, depositing their mass ... D.,Janches,L.,... - 《Geophysical Research Letters》 被引量...
Conversion of sodium chloride to hydrogen chloride in the atmosphere A reaction route is suggested, based on experimental results, for the conversion of sodium chloride particles to gaseous hydrogen chloride in the atmospher... RC Robbins,RD Cadle,DL Eckhardt 被引量: 181发表: 1959年 Airborne Stud...
, mankind’s use of Earth’s resources has grown so much that it seems justified to denominate the past two centuries into the future as a new geological epoch: ‘The Anthropocene’. This transition is also marked by major changes in the chemistry and chemical composition of the atmosphere....
limiting stage of the chain processIn this paper, we consider the unresolved problems of chemistry of the middle atmosphere related to the atmospheric lifetime of the O x family and its O 3 , O( 3 P ), and O( 1 D ) components, as well as problems associated with the odd oxygen ...
