Investigation of the global methane budget over 1980–2017 using GFDL-AM4.1 [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
Changes in atmospheric methane abundance have implications for both chemistry and climate as methane is both a strong greenhouse gas and an important precursor for tropospheric ozone.

Hotspot Detection and Estimation of Methane Emissions from Landfill Final Cover

open access: yesAtmosphere, 2023
The main objectives of this study were to identify methane hotspots through spatial distribution tests of the surface methane concentration above a landfill final cover and to investigate the effects of rainfall, atmospheric pressure, ground temperature,

The impact of air pollutant and methane emission controls on tropospheric ozone and radiative forcing: CTM calculations for the period 1990-2030 [PDF]

open access: yes, 2004
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), carbon monoxide (CO), non-methane volatile organic ...

Composting and Methane Emissions of Coffee By-Products [PDF]

open access: yesAtmosphere, 2021
In the last 20 years, the demand for coffee production has increased detrimentally, heightening the need for production, which is currently driving the increase in land cultivation for coffee. However, this increase in production ultimately leads to the amplification of waste produced.

Four-dimensional variational data assimilation for inverse modelling of atmospheric methane emissions: method and comparison with synthesis inversion [PDF]

open access: yes, 2008
A four-dimensional variational (4D-Var) data assimilation system for inverse modelling of atmospheric methane emissions is presented. The system is based on the TM5 atmospheric transport model.

THE CONTRIBUTION OF HYDROTHERMAL «SMOKERS», MUD VOLCANOES AND GAS SEEPS TO THE EARTH’S HEAT EFFECT

open access: yesГеологія і корисні копалини Світового океану, 2021
The problem of increasing the concentration in the atmosphere of one of the dangerous heat gases - methane, the main component of natural gas. Many countries, especially the developed world, are now experiencing a trend towards tougher heat gas emissions

The Lore of Low Methane Livestock:Co-Producing Technology and Animals for Reduced Climate Change Impact [PDF]

open access: yes, 2013
Methane emissions from sheep and cattle production have gained increasing profile in the context of climate change. Policy and scientific research communities have suggested a number of technological approaches to mitigate these emissions.

Role of climate feedback on methane and ozone studied with a coupled ocean-atmosphere-chemistry model. [PDF]

open access: yes, 2001
We present results from two experiments carried out with a coupled ocean-atmosphere-tropospheric chemistry model run continously over the period 1990 to 2100.

Reduced methane emissions from large-scale changes in water management of China’s rice paddies during 1980-2000 [PDF]

open access: yes, 2002
Decreased methane emissions from paddy rice may have contributed to the decline in the rate of increase of global atmospheric methane (CH4) concentration over the last 20 years. In China, midseason paddy drainage, which reduces growing season CH4 fluxes,
