Sentences with phrase «stratospheric chemistry»
"Stratospheric chemistry" refers to the chemical reactions and processes that occur in the stratosphere, a layer of Earth's atmosphere above the troposphere. It involves studying how different substances interact and change in this particular atmospheric region. Full definition
Through extensive modeling of stratospheric chemistry, the team found that calcite, a constituent of limestone, could counter ozone loss by neutralizing emissions - borne acids in the atmosphere, while also reflecting light and cooling the planet.

Other GCM calculations, which include interactive stratospheric chemistry with ozone, had more success in predicting an 11 - year climate cycle.
Ozone climatology: Some chemistry / aerosol models will run with interactive stratospheric chemistry while others will prescribe ozone in the stratosphere and only run with detailed tropospheric chemistry.
Takigawa, M., M. Takahashi, and H. Akiyoshi, 1999: Simulation of ozone and other chemical species using a Center for Climate Systems Research / National Institute for Environmental Studies atmospheric GCM with coupled stratospheric chemistry, J. Geophys.
Submission of all other fields are strongly encouraged (those that are available, e.g. models without stratospheric chemistry do not need to submit the stratospheric diagnostics).
By ruling out the unsuitable elements on the periodic table and then through modeling of stratospheric chemistry, the team landed on calcite, a constituent of rocks like limestone, marble and chalk, and one of the Earth's crust's most common compounds.
For a view from the ground, my friend and colleague, Hans Brenna, a climate researcher currently investigating the role of volcanoes on stratospheric chemistry, believes that the logical result of arguments against advocacy are a slippery slope.
«Stratospheric chemistry is complicated and we don't understand everything about it,» Keith said.
«Stratospheric chemistry is complicated and we don't understand everything about it.
He said experts must more closely study the feasibility of the idea and its possible effects on stratospheric chemistry.
Stratospheric chemistry isn't a straightforward science — it relies on atmospheric concentrations of ozone, oxygen, hydroxyl radicals (which are also necessary to convert methane to CO2, among other things), CO2, nitrogen, the availability of solar radiation in various wavelengths, humidity, prevailing winds, and so on.
The only one that is simple and cheap enough to be seriously discussed at the moment was put forward by Paul Crutzen, awardee of the Nobel Prize for advancing our understanding of the stratospheric chemistry to the ozone layer.
