What are the greenhouse gas and air pollutant emissions factors?

» Some atmospheric gases absorb and re-emit infrared light from the atmosphere to the ground. The greenhouse effect causes a mean surface temperature that is 33 degrees Celsius higher than it would be otherwise. Without the greenhouse gas effect, the average temperature on Earth would be a frigid 18°C.

» Because of trace amounts of water vapor (H2O), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) in the atmosphere, the Earth has a natural greenhouse effect. These gases allow solar light to reach the Earth's surface, but also absorb infrared radiation generated by the Earth, causing the planet's surface to heat up. The natural greenhouse effect must be distinguished from the increased greenhouse effect. The natural greenhouse effect is created by naturally occurring levels of greenhouse gases and is essential to life. Without the natural greenhouse effect, the Earth's surface would be around 33 degrees Celsius colder.

» The enhanced greenhouse effect refers to the extra radioactive forcing caused by higher greenhouse gas concentrations caused by human activity. Carbon dioxide, methane, nitrous oxide, hydro chlorofluorocarbons (HCFCs), hydro fluorocarbons (HFCs), and ozone are the principal greenhouse gases whose concentrations are increasing in the lower atmosphere.

» The Global Atmosphere Watch (GAW) monitors, analyses, and disseminates greenhouse gas data gathered by fifty countries from the High Arctic to the South Pole.



The following greenhouse gases are being monitored:

• Carbon Dioxide (CO2) (incl. Δ14C, δ13C and δ18O in CO2, and O2/N2 Ratios)

• Methane (CH4)

• Nitrous Oxide (N2O)

• Halocarbons and SF6

• Molecular Hydrogen (H2)

The World Data Centre for Greenhouse Gases (WDCGG) of the Japan Meteorological Agency collects and distributes the data. GAW's Scientific Advisory Group for Greenhouse Gases (SAG-GHG) provides guidance on program development. The Greenhouse Gas Bulletin is published annually by GAW and informs on the current trends and atmospheric loads of the most prominent, long-lived greenhouse gases, carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), as well as a synopsis of the contributions of the smaller gases.

Global Greenhouse Gas Monitoring Infrastructure

Improving our Understanding of the Carbon Cycle

The GHG monitoring system will contribute to a better understanding of the carbon cycle.

The provision of globally consistent, gridded information on greenhouse gases and their fluxes with adequate time resolution would aid in the enhanced evaluation of greenhouse gas sources and sinks, as well as their link with the biosphere, the ocean, and permafrost regions.

Understanding the entire carbon cycle is critical for designing mitigation actions. "The global carbon cycle governs the quantity of carbon dioxide and methane that accumulates in the atmosphere, increasing the Earth's greenhouse effect. As a result, it is an important component of the global climate system. The carbon cycle also responds to climate change, and knowing the carbon cycle's potential to continue acting as a partial sink of fossil fuel emissions in the future will be critical in calculating the "allowable" fossil fuel emissions while maintaining concentrations below specific thresholds" (GEO Carbon Strategy).
