Methane: Interhemispheric concentration gradient and atmospheric residence time.
The ground level concentrations of methane in the atmosphere have been measured to be in the range from 1.45 to 1.62 parts per million by volume (ppmv) of dry air in remote locations between 62 degrees N and 54 degrees S latitudes during the time period from November 1977 to July 1979. The average (+/-rms) concentration for the northern hemisphere was 1.57 +/- 0.02 ppmv in January 1978 and 1.59...
متن کاملAtmospheric methane and global change
Methane (CH4) is the most abundant organic trace gas in the atmosphere. In the distant past, variations in natural sources of methane were responsible for trends in atmospheric methane levels recorded in ice cores. Since the 1700s, rapidly growing human activities, particularly in the areas of agriculture, fossil fuel use, and waste disposal, have more than doubled methane emissions. Atmospheri...
متن کاملAtmospheric Methane: Trends and Impacts
The concentration of methane (CH4), the most abundant organic trace gas in the atmosphere, has increased dramatically over the last few centuries, more than doubling its concentration. The increasing concentrations of methane are of special concern because of its effects on climate and atmospheric chemistry. On a per molecule basis, additional methane is much more effective as a greenhouse gas ...

that of the host eye only. Previous work on the neuromuscular and various other systems including the retinotectal projection also indicate no direct inhibitory effect of 1TX on axoplasmic transport (12) nor on the capacity offibers to grow, arborize, and form synapses (13). Histology on 12 representative retinas revealed no pathology. The formation of gross retinotopography-as shown by the gro...
متن کاملRenewed growth of atmospheric methane
[1] Following almost a decade with little change in global atmospheric methane mole fraction, we present measurements from the Advanced Global Atmospheric Gases Experiment (AGAGE) and the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) networks that show renewed growth starting near the beginning of 2007. Remarkably, a similar growth rate is found at all monitori...
