Diurnal Variation of Two Greenhouse Gases in Beijing
|
Abstract:
One year continuous measurements on methane and carbon dioxide were carried out in Beijing.Their diurnal variation and relationship are studied in detail.Analyzing results indicate that diurnal variation of carbon dioxide has a pattern with two peaks,while methane's diurnal variation with one peak.Statistical analysis also shows that correlation of this two greenhouse gases' diurnal variation is highly significant.The pattern of these two greenhouse gases' diurnal variation can be attributed to periodical variation of daily meteorological factor and their source-sink structure.
