First ground-based FTIR observations of methane in the inner tropics over several years
First ground-based FTIR observations methane the inner tropics
2010/8/16
Total column concentrations of methane have been retrieved from ground-based solar absorption FTIR spectra in the near-infrared recorded in Paramaribo (Suriname). The methane FTIR observations are com...
PTR-MS measurements of non-methane volatile organic compounds during an intensive field campaign at the summit of Mount Tai, China, in June 2006
PTR-MS measurements non-methane volatile organic compounds an intensive field campaign June 2006
2010/8/16
Owing to recent industrialization, Central East China has become a significant source of air pollutants. To examine the processes controlling the chemistry and transport of tropospheric ozone, we perf...
Characterization of methane retrievals from the IASI space-borne sounder
methane retrievals IASI space-borne sounder
2009/11/9
Although the global methane (CH4) concentration has more than doubled since pre-industrial times, local emission sources are still poorly identified and quantified. Instruments onboard satellites can ...
Tropospheric methane in the tropics – first year from IASI hyperspectral infrared observations
Tropospheric methane tropics IASI hyperspectral infrared observations
2009/9/11
Simultaneous observations from the Infrared Atmospheric Sounding Interferometer (IASI) and from the Advanced Microwave Sounding Unit (AMSU), launched together onboard the European MetOp platform in Oc...
Validation of version-4.61 methane and nitrous oxide observed by MIPAS
version-4.61 methane nitrous oxide MIPAS
2009/3/12
The ENVISAT validation programme for the atmospheric instruments MIPAS, SCIAMACHY and GOMOS is based on a number of balloon-borne, aircraft, satellite and ground-based correlative measurements. In par...
Halogen Occultation Experiment (HALOE) and balloon-borne in situ measurements of methane in stratosphere and their relation to the quasi-biennial oscillation（QBO）
Halogen Occultation Experiment HALOE quasi-biennial oscillation QBO
2009/3/11
Measurements of methane have been made from various observational platforms in the atmosphere. In this article, we have compared four high precision balloon-borne measurements from Hyderabad (17.5°N),...
Trends and inter-annual variability of methane emissions derived from 1979-1993 global CTM simulations
Trends and inter-annual variability methane emissions global CTM simulations
2009/3/10
The trend and interannual variability of methane sources are derived from multi-annual simulations of tropospheric photochemistry using a 3-D global chemistry-transport model. Our semi-inverse analysi...
The impact of air pollutant and methane emission controls on tropospheric ozone and radiative forcing: CTM calculations for the period 1990-2030
air pollutant methane emission tropospheric ozone CTM
2009/2/12
To explore the relationship between tropospheric ozone and radiative forcing with changing emissions, we compiled two sets of global scenarios for the emissions of the ozone precursors methane (CH4), ...
Atmospheric methane and carbon dioxide from SCIAMACHY satellite data: initial comparison with chemistry and transport models
Atmospheric methane carbon dioxide SCIAMACHY satellite data chemistry and transport models

The remote sensing of the atmospheric greenhouse gases methane (CH4) and carbon dioxide (CO2) in the troposphere from instrumentation aboard satellites is a new area of research. In this manuscript, r...
Methane emission from tropical savanna Trachypogon sp. grasses
Methane emission tropical savanna Trachypogon sp. grasses
2009/1/20
Methane flux measurements from the soil-grass system were made during the wet season in unperturbed plots and plots where standing dry and green Trachypogon sp. grasses were clipped to just above the ...
Effects of methane outgassing on the Black Sea atmosphere
Effects of methane outgassing Black Sea atmosphere
2009/1/19
Methane in air and seawater was measured in the Eastern Black Sea during the 10–18 December 1999 BIGBLACK project cruise. The measurements allowed for the calculation of supersaturation ratios and me...

In situ continuous hourly measurements of C2–C8 non-methane hydrocarbons (NMHCS) have been performed from March to October 2006 at two coastal locations (natural and rural) on the island of Crete, in ...
The atmospheric cycling of radiomethane and the“fossil fraction”of the methane source
radiomethane fossil fraction methane
2008/12/8
The cycling of 14CH4 ("radiomethane") through the atmosphere has been strongly perturbed in the industrial era by the release of 14C-free methane from geologic reservoirs ("fossil methane" emissions),...
