Detection and quantification of agricultural methane plumes using MethaneAIR through targeted scene selection, wavelet denoising, and divergence-integral analysis

Penelope Smale, Alexander Geddes, S. E. Mikaloff Fletcher, Zhan Zhang et autres

Methane is a potent greenhouse gas, and accurate emission estimates are essential for effective climate mitigation. Agricultural sources, particularly concentrated animal feeding operations (CAFOs), are significant anthropogenic contributors, yet their emissions remain difficult to quantify, contributing to uncertainty in inventories. MethaneAIR, an …

Unveiling Carbon Sequestration Dynamics in Bamboo Forests, China: An Observation-Based Approach Using Atmospheric Tracers

Shuangxi Fang, Oksana Tarasova, YanXia Li, Jocelyn Turnbull et autres

Bamboo, a perennial grass species, exhibits rapid growth rates surpassing many native trees, offering substantial potential for atmospheric carbon capture and subsequent sequestration into durable products. Despite this promise, the carbon sequestration capacity of bamboo forests and its variability under different land …

Southern Hemisphere tree rings as proxies to reconstruct Southern Ocean upwelling

Christian B. Lewis, Rachel Corran, S. E. Mikaloff Fletcher, Erik Behrens et autres

The Southern Ocean plays a key role in regulating global climate and acting as a carbon sink. This region, defined as south of 35° S, is accountable for 40 % of all oceanic anthropogenic CO 2 uptake and 75 % of ocean …

Latitudinal Distribution of Atmospheric Radiocarbon over the Southern Ocean Driven by Ocean Upwelling

Jocelyn Turnbull, Nikita Turton, Mus Hertoghs, Julia Collins et autres

The Southern Ocean is a key anthropogenic carbon dioxide (CO2) sink, yet the processes governing the rate of uptake remain only partly understood. We use observations of radiocarbon (∆14C) in CO2 from Southern Ocean shipboard transects to develop latitudinal gradients of ∆14C …

Inverse modelling of New Zealand's carbon dioxide balance estimates a larger than expected carbon sink

Beata Bukosa, S. E. Mikaloff Fletcher, Gordon Brailsford, Dan Smale et autres

Accurate national-scale greenhouse gas source and sink estimates are essential to track climate mitigation efforts. Inverse models can complement inventory-based approaches for emissions reporting by providing independent estimates underpinned by atmospheric measurements, yet few nations have developed this capability for carbon dioxide …
