The infrared bands of chlorofluorocarbons and chlorocarbons enhance the atmospheric greenhouse effect. This enhancement may lead to an appreciable increase in the global surface temperature if the atmospheric concentrations of these compounds reach values of the order of 2 parts per billion. 

Greenhouse effect of chlorofluorocarbons and other trace gases

A comparison is made of the radiative (greenhouse) forcing of the climate system due to changes of atmospheric chlorofluorocarbons and other trace gases. It is found that CFCs, defined to include

Greenhouse effect due to atmospheric nitrous oxide

The greenhouse effect due to nitrous oxide in the present atmosphere is about 0.8°K. Increase in atmospheric N_2O due to perturbation of the nitrogen cycle by man may lead to an increase in surface

Infrared intensities of some chlorofluorocarbons capable of perturbing the global climate

The absolute intensities of the strong infrared absorption bands of several chlorofluorocarbons (CFCs) located in the atmospheric window have been measured. The CFCs studied in the present

This paper describes recent efforts to assess the risk of anthropogenic increases of UV-B radiation and changes of climate at the earth's surface. The main intent of the paper is to provide the

Atmospheric Fluorocarbons: Possible Effects of a Large Increase on the Global Climate

For the past two years there has been growing concern over the potential environmental effects of fluorocarbons (chlorofluoromethanes, primarily CF2C12 and CFC13) in the atmosphere. Originating

Greenhouse Effects due to Man-Made Perturbations of Trace Gases

A one-dimensional radiative-convective model for the atmospheric thermal structure is used to compute the change in the surface temperature of the earth for large assumed increases in the trace gas concentrations; doubling the N2O, CH4, and NH3 concentrations is found to cause additive increases inthe surface temperature.

The Effects of Chlorofluoromethanes on Climate

The chlorofluoromethanes, CFCl3, CF2Cl2 are chemically quite inert. Their atmospheric destruction is slow and takes place essentially in the stratosphere. With present release rates the tropospheric

Chlorocarbon emission scenarios: Potential impact on stratospheric ozone

Prior analyses of chlorocarbons and their effects on stratospheric ozone have primarily concentrated on examining potential perturbations from two chlorofluorocarbons, CFCl3 (CFC-11) and CF2Cl2



Stratospheric Ozone Destruction by Man-Made Chlorofluoromethanes

Present usage levels of chlorofluoromethanes can lead to chlorine-catalyzed ozone destruction rates that will exceed natural sinks of ozone by 1985 or 1990.

Stratospheric sink for chlorofluoromethanes: chlorine atomc-atalysed destruction of ozone

Chlorofluoromethanes are being added to the environment in steadily increasing amounts. These compounds are chemically inert and may remain in the atmosphere for 40–150 years, and concentrations can

Atmospheric halocarbons and stratospheric ozone

ODD chlorine1 is a more potent catalyst for the destruction of ozone than is odd nitrogen2. Molina and Rowland3 warn that chlorine released during the photochemical destruction of fluorocarbons

Atmospheric Carbon Dioxide and Aerosols: Effects of Large Increases on Global Climate

Effects on the global temperature of large increases in carbon dioxide and aerosol densities in the atmosphere of Earth have been computed. It is found that, although the addition of carbon dioxide

Estimate of late 1974 stratospheric concentration of gaseous chlorine compounds (ClX)

We estimate the total concentration [ClX] versus altitude of Cl‐containing molecules, principally HCl, Cl and ClO. The predicted present stratospheric concentrations appear to be due to photolysis

The water‐vapour infra‐red continuum

All published work on the water-vapour continuum in the region 8 μ to 50 μ is reviewed in the light of some new experimental results in the 11 to 21 -μ region. This new work employed a 15.5 m

Vibrational Intensities. VIII. CH3 and CD3 Chloride, Bromide, and Iodide

Absolute intensity measurements have been made on the fundamental vibrations of methyl chloride, bromide, and iodide, and their fully deuterated derivatives, by integrating the optical density over
