The Summary for Policymakers (SPM) of the Synthesis Report (SYR) Sixth Assessment (AR6) Intergovernmental Panel on Climate Change (IPCC), is a component SYR which provides policy-relevant but policy-neutral summary SYR. It consistent with Sections and approved line by Governments at plenary session Change.
Abstract. The Amazon Basin plays key role in atmospheric chemistry, biodiversity and climate change. In this study we applied nanoelectrospray (nanoESI) ultra-high-resolution mass spectrometry (UHRMS) for the analysis of organic fraction PM2.5 aerosol samples collected during dry wet seasons at a site central Amazonia receiving background air masses, biomass burning urban pollution. Comprehensive spectral data evaluation methods (e.g. Kendrick defect, Van Krevelen diagrams, carbon oxidation...
Abstract Secondary organic aerosol (SOA) accounts for a dominant fraction of the submicron atmospheric particle mass, but knowledge formation, composition and climate effects SOA is incomplete limits our understanding overall in atmosphere. Organic oligomers were discovered as components over decade ago laboratory experiments have since been proposed to play role many processes. However, it remains unclear whether are relevant under ambient conditions because they often not clearly observed...
Abstract. We describe the motivation, design, and execution of Greenhouse gAs Uk Global Emissions (GAUGE) project. The overarching scientific objective GAUGE was to use atmospheric data estimate magnitude, distribution, uncertainty UK greenhouse gas (GHG, defined here as CO2, CH4, N2O) budget, 2013–2015. To address this objective, we established a multi-year interlinked measurement analysis programme, building on an tall-tower GHG network. calibrated network comprises ground-based, airborne,...
Abstract. High methane (CH4) mixing ratios (up to 4 ppm) have occurred sporadically at our measurement site in Haddenham, Cambridgeshire, since July 2012. Isotopic measurements and back trajectories show that the source is Waterbeach Waste Management Park 7 km SE of Haddenham. To investigate this further, were made on 30 June 1 2015 other locations nearer source. Landfill emissions been estimated using three different approaches scales; near WindTrax inversion dispersion model, middle...
The chemical breakdown of organic matter in landfills represents a significant source methane gas (CH4). Current estimates suggest that are responsible for between 3% and 19% global anthropogenic emissions. net CH4 emissions resulting from biogeochemical processes their modulation by microbes poorly constrained imprecise knowledge environmental constraints. uncertainty absolute is therefore considerable. This study investigates new method to estimate the temporal variability using...
Abstract. Early-career scientists (ECSs) are a large part of the workforce in science. While they produce new scientific knowledge that share publications, rarely invited to participate peer-review process. Barriers participation ECSs as peer reviewers include, among other things, their lack visibility editors, inexperience review process and confidence knowledge. Participation group reviews, e.g. for regional or global assessment reports, provides an opportunity advance skill set contribute...

Abstract The Intergovernmental Panel on Climate Change (IPCC) has been producing influential reports for over 35 years. As the IPCC’s Seventh Assessment Report (AR7) cycle begins, we offer our perspective as former members of IPCC Technical Support Units from Working Groups I, II & III, and Synthesis lessons learned during Sixth (AR6) cycle. We identify three broad issues that, if addressed, could reinforce sustain in continuing its mission to comprehensively assess scientific...
Abstract In its Sixth Assessment Report Cycle (AR6), the Intergovernmental Panel on Climate Change (IPCC) aims to strengthen communication of products. As only mandatory part IPCC reports specifically targeting a lay audience, Frequently Asked Questions (FAQs) provide an opportunity for broader key topics. AR6 has released three Special Reports that include FAQs, varying in number and structure, as well approach taken develop them. Using these this essay, we take stock current efforts...
Abstract. Methane is a strong contributor to global climate change, yet our current understanding and quantification of its sources their variability incomplete. There growing need for comparisons between emission estimates produced using bottom-up inventory approaches top-down inversion techniques based on atmospheric measurements, especially at higher spatial resolutions. To meet this need, study presents an approach the Inversion Technique Emissions Modelling (InTEM) framework...

Isotopic measurements and back trajectories show that the source is Waterbeach Waste management park 7 km SE of Haddenham. To investigate this further, were made on June 30th 1st 2015 other locations nearer source. Landfill emissions been estimated using three different approaches (WindTrax, Gaussian plume, NAME InTEM inversion) applied...
