Sentences with phrase «ozone chemistry»

There they spread globally and can influence the composition of the air for many years — with far - reaching consequences for ozone chemistry, aerosol formation and climate.

This in turn has been linked to solar UV / ozone chemistry translated through atmospheric pathways to polar surface pressure.

Isoprene, an organic compound produced and emitted into the atmosphere by many tree species, plays an important role in tropospheric ozone chemistry and in formation of SOA particles.

Sassi, F., B.A. Boville, D. Kinnison, and R.R. Garica, 2005: The effects of interactive ozone chemistry on simulations of the middle atmosphere, Geophys.

Simone Tilmes, a project scientist at the National Center for Atmospheric Research in Boulder, Colorado, added that salt often includes iodine, a reactive element that could not just impact ozone chemistry in the troposphere but also affect chemical reactions in the stratosphere.

At the same time — research is showing a solar UV / ozone chemistry influence in modulating atmospheric flows and polar pressure fields.

The authors of the paper I started with suggest that solar UV / ozone chemistry affects are translated through atmospheric pathways to modulate surface pressure at the poles.

Users of chemistry - climate models (CCMs) with particular focus on long - term numerical simulations using CCMs for the detailed investigation of model feedbacks between ozone chemistry, ozone depleting substance (ODS) trends, and climate.

Much work is being done on improving the realism of such effects — particularly through ozone chemistry (which enhances the signal), and aerosol pathways (which don't appear to have much of a global effect i.e. Dunne et al. (2016)-RRB-.

Having said that, modelling aviation effects is complicated — involving ozone chemistry, strat / trop exchange, aerosols, CO2, contrails, water vapour etc. — all of which interact to some degree, and which have very different timescales.

This is important for the light that it shines on tropospheric ozone chemistry («bad ozone») which is a contributing factor to global warming (albeit one which is about only about 20 % as important as CO2).

Thus while in theory, a revision in ozone chemistry, or soil respiration or aerosol properties might impact the full ESM, it won't affect the more basic stuff (like the sensitivity to CO2).

In the field of planetary and atmospheric sensing, linear arrays capable of simultaneously measuring height - resolved spectral features would have a major impact on issues such as climate change and ozone chemistry,» explains Peter de Maagt, ESA's project manager for Star Tiger.

There have been many explanations put borth inlcluding deep ocean heating, ozone chemistry, volcanoes reducing incident energy, trade winds and, of course, Cowtan and Way along with this latest data set that shows the energy imbalance is still tracking CO2.

The details of the ocean and atmospheric links are fascinating — it is postulated that it starts with solar uv / ozone chemistry modulating ocean and atmospheric circulation throughout the system.

The mechanism involves solar UV / ozones chemistry.

There is considerable interest in a sun and NAM (and SAM) connections via UV / ozone chemistry and modulating Earth system flows — especially equator to pole stratospheric and tropospheric pathways.

A number of leading scientists, for instance, Paul Crutzen, who had won a Nobel Prize for his work on atmospheric ozone chemistry, told Jim that he had put together just the sort of comprehensive and convincing presentation that was needed.

The mechanism is UV / ozone chemistry modulating both the northern and southern annular modes — spinning up winds and currents at lower latitudes and biasing the system to more or less upwelling in the eastern Pacific.

Yet this is completely misleading since neither climate sensitivity nor CO2 driven future warming will be at all affected by any revisions in ozone chemistry — mainly for the reason that most climate models don't consider ozone chemistry at all.

In a new study, we examined how Arctic sea ice retreat could impact oxidation and tropospheric ozone chemistry.
