Sentences with phrase «for halocarbons»

Totally different for halocarbons in the 8 - 12um range compared with CO2 at 15um — for example.

Not exact matches

Some greenhouse gases (most of the halocarbons, for example) have no natural source.

Results show that the globally and annually averaged radiative forcing caused by the observed loss of sea ice in the Arctic between 1979 and 2007 is approximately 0.1 W m − 2; a complete removal of Arctic sea ice results in a forcing of about 0.7 W m − 2, while a more realistic ice - free - summer scenario (no ice for one month, decreased ice at all other times of the year) results in a forcing of about 0.3 W m − 2, similar to present - day anthropogenic forcing caused by halocarbons.

Consequently, the most advanced climate models now require, in addition to concentrations or emissions of greenhouse gases (CO2, CH4, N2O and halocarbons), emissions of reactive gases and aerosol precursor compounds (SO2, NOx, VOC, BC, OC and NH3), to model atmospheric chemistry and interactions with the climate system.6 For most variables, a sectoral differentiation would improve the quality of the calculations (e.g. from power plants and agricultural burning).

Requirements for the preparation and implementation of pollution prevention plans for sound end - of - life management of halocarbon refrigerants were also recently published.

We validated parameterization of the model diffusivity using CH4 and three halocarbon species (CFC11, CFC113, and CCl4) for which atmospheric histories have been estimated from emission scenarios and real - time measurements (60 — 62).

The introduction of halocarbons in the mid-20th century has contributed an additional +0.34 Wm for a total forcing by WMGHGs of +2.45 Wm with a 15 % margin of uncertainty.
