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

, 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.

Design, Build, and Initial Testing of a Portable Methane Measurement Platform

Sensors
The quantification of methane concentrations in air is essential for the quantification of methane emissions, which in turn is necessary to determine absolute emissions and the efficacy of emission mitigation strategies.

DPSR-based study and assessment of the influence pathways of Shanghai urban development level on river methane emission potential during 2011–2020

Ecological Indicators, 2023
Numerous studies have shown that urban rivers are becoming a source of methane emissions, which poses a challenge to developing a “net zero carbon city.” Most studies at this stage focus on the influence of single urban elements on river methane ...

A Review of Offshore Methane Quantification Methodologies

Atmosphere
Since pre-industrial times, anthropogenic methane emissions have increased and are partly responsible for a changing global climate. Natural gas and oil extraction activities are one significant source of anthropogenic methane.

Assessment of financial and environmental impacts of pre-mining methane drainage in Indian scenario: A case study using Jharia coal seams

Innovation and Green Development, 2023
Global coal deposits are often associated with trapped methane, whose nature and composition are similar to that of the natural gas. Compared to coal, this trapped methane is a superior as well as cleaner fuel but its fugitive emission from coal mines is

Variability in aerobic methane oxidation over the past 1.2 Myrs recorded in microbial biomarker signatures from Congo fan sediments [PDF]

, 2014
Methane (CH4) is a strong greenhouse gas known to have perturbed global climate in the past, especially when released in large quantities over short time periods from continental or marine sources.

Methane production, emission and control during MSW landfilling. [PDF]

, 2003
Until quite recently the major emphasis on landfill gas control has related to ‘postcompletion’ of landfill cells or phases, rather than during active waste disposal operations. Increasingly, odour control needs have changed that pattern through ad hoc
