Enhanced CH emissions from global wildfires likely due to undetected small fires.

Monitoring methane (CH) emissions from terrestrial ecosystems is essential for assessing the relative contributions of natural and anthropogenic factors leading to climate change and shaping global climate goals. Fires are a significant source of atmospheric CH, with the increasing frequency of megafires amplifying their impact. Global fire emissions exhibit large spatiotemporal variations, making the magnitude and dynamics difficult to characterize accurately.

Mapping emissions in Cyprus using TROPOMI observations: evaluation of the flux-divergence scheme using multiple parameter sets.

The production of nitrogen oxides (NO = NO + NO ) is substantial in urban areas and from fossil fuel-fired power plants, causing both local and regional pollution, with severe consequences for human health. To estimate their emissions and implement air quality policies, authorities often rely on reported emission inventories. The island of Cyprus is de facto divided into two different political entities, and as a result, such emissions inventories are not systematically available for the whole island.

Recent methane surges reveal heightened emissions from tropical inundated areas.

Record breaking atmospheric methane growth rates were observed in 2020 and 2021 (15.2±0.5 and 17.

Low latency carbon budget analysis reveals a large decline of the land carbon sink in 2023.

In 2023, the CO growth rate was 3.37 ± 0.11 ppm at Mauna Loa, which was 86% above that of the previous year and hit a record high since observations began in 1958, while global fossil fuel CO emissions only increased by 0.

Refining the Global Picture: The Impact of Increased Resolution on CO Atmospheric Inversions Using OCO-2 XCO Retrievals.

The threat posed by the increasing concentration of carbon dioxide (CO) in the atmosphere motivates a detailed and precise estimation of CO emissions and removals over the globe. This study refines the spatial resolution of the CAMS/LSCE inversion system, achieving a global resolution of 0.7° latitude and 1.
