This research presents an assessment of fugitive methane emissions from a liquefied natural gas (LNG) power plant in Seoul, using a mobile greenhouse gas (GHG) measurement platform. Three key emission hotspots were identified, including continuous methane leaks and one stochastic super-emitter from the LNG power plant facilities. Our measurements revealed significant discrepancies compared to bottom-up inventories, which fail to capture these intermittent, high-emission events.

We evaluate a new model simulating soil uptake of methane and hydrogen from the atmosphere. Coupled to an atmospheric chemistry and land surface model, it accounts for weather and soil conditions. Our results match observations, showing accurate removal depending on soil properties, temperature, moisture, and atmospheric conditions. This work improves the model’s ability to represent natural cycles of methane and hydrogen.

We develop a hybrid inverse modeling framework that combines FDMB with 4D-Var to jointly optimize NOₓ and VOC emissions at hourly resolution. Using TROPOMI and surface observations, the system yields substantial diurnal emission adjustments and improves ozone simulations. The optimized emissions shift ozone sensitivity regimes and show that emissions from 1–2 hours earlier have the strongest influence on current O₃, providing actionable, time-resolved guidance for effective mitigation.

This study develops a high-resolution inverse modeling framework that combines ground-based and satellite CO2 observations to improve urban emission estimates in Seoul. By integrating atmospheric data and transport models, the research reduces uncertainties in CO2 emissions and reveals spatial and temporal patterns. The method offers a valuable tool for supporting climate policies and can be applied to other cities for better emission verification.

We investigated the responses of mangroves to temperature and solar radiation, and further projected future climate favourability for mangroves across East Asia. East Asian mangrove growth is positively linked to temperature and solar radiation, particularly in cumulative anomalies on seasonal time scales. Winter isotherm shifts suggest northward mangrove expansion under global warming, but low solar radiation from aerosol emissions in East Asia may still constrain their growth.

Changes in the carbon stocks of terrestrial ecosystems result in emissions and removals of CO2. These can be driven by anthropogenic activities (e.g., deforestation), natural processes (e.g., fires) or in response to rising CO2 (e.g., CO2 fertilization). This paper describes a dataset of CO2 emissions and removals derived from atmospheric CO2 observations. This pilot dataset informs current capabilities and future developments towards top-down monitoring and verification systems.

Space-borne greenhouse gas missions require ground-based validation networks capable of providing fiducial reference measurements. Here, considerable refinements of the calibration procedures for the COllaborative Carbon Column Observing Network (COCCON) are presented. Laboratory and solar side-by-side procedures for the characterization of the spectrometers have been refined and extended. Revised calibration factors for XCO2, XCO and XCH4 are provided, incorporating 47 new spectrometers.

Short summary
This study uses data and machine learning to better estimate methane emissions from a major landfill in South Korea. By considering local weather conditions like temperature and rain, the research improves how landfill methane is tracked over time. The results help us understand how climate affects emissions and provide tools that can be used worldwide to improve greenhouse gas monitoring and climate action planning.
