Autor: T. Eidhammer, A. Gettelman, K. Thayer-Calder, D. Watson-Parris, G. Elsaesser, H. Morrison, M. van Lier-Walqui, C. Song, D. McCoy

Publikováno v: Geoscientific Model Development, Vol 17, Pp 7835-7853 (2024)

This paper documents the methodology and preliminary results from a perturbed parameter ensemble (PPE) technique, where multiple parameters are varied simultaneously and the parameter values are determined with Latin hypercube sampling. This is done

Interactions between atmospheric composition and climate change – progress in understanding and future opportunities from AerChemMIP, PDRMIP, and RFMIP

Publikováno v: Geoscientific Model Development, Vol 17, Pp 2387-2417 (2024)

The climate science community aims to improve our understanding of climate change due to anthropogenic influences on atmospheric composition and the Earth's surface. Yet not all climate interactions are fully understood, and uncertainty in climate mo

Has Reducing Ship Emissions Brought Forward Global Warming?

Autor: A. Gettelman, M. W. Christensen, M. S. Diamond, E. Gryspeerdt, P. Manshausen, P. Stier, D. Watson‐Parris, M. Yang, M. Yoshioka, T. Yuan

Publikováno v: Geophysical Research Letters, Vol 51, Iss 15, Pp n/a-n/a (2024)

Abstract Ships brighten low marine clouds from emissions of sulfur and aerosols, resulting in visible “ship tracks”. In 2020, new shipping regulations mandated an ∼80% reduction in the allowed fuel sulfur content. Recent observations indicate t

How well are aerosol–cloud interactions represented in climate models? – Part 1: Understanding the sulfate aerosol production from the 2014–15 Holuhraun eruption

Autor: G. Jordan, F. Malavelle, Y. Chen, A. Peace, E. Duncan, D. G. Partridge, P. Kim, D. Watson-Parris, T. Takemura, D. Neubauer, G. Myhre, R. Skeie, A. Laakso, J. Haywood

Publikováno v: Atmospheric Chemistry and Physics, Vol 24, Pp 1939-1960 (2024)

For over 6 months, the 2014–2015 effusive eruption at Holuhraun, Iceland, injected considerable amounts of sulfur dioxide (SO2) into the lower troposphere with a daily rate of up to one-third of the global emission rate, causing extensive air pollu

Integration of genomic aberrations to predict clinical outcomes for patients with gastroesophageal adenocarcinoma receiving neoadjuvant chemotherapy

Publikováno v: ESMO Gastrointestinal Oncology, Vol 3, Iss , Pp 100010- (2024)

Background: Esophageal cancer [esophagogastric adenocarcinoma (OGA)] shows heterogeneity at the molecular level, leading to lower efficacy rates and highlighting the need for personalized treatment strategies. We have developed a computational model

Rapid saturation of cloud water adjustments to shipping emissions

Autor: P. Manshausen, D. Watson-Parris, M. W. Christensen, J.-P. Jalkanen, P. Stier

Publikováno v: Atmospheric Chemistry and Physics, Vol 23, Pp 12545-12555 (2023)

Human aerosol emissions change cloud properties by providing additional cloud condensation nuclei. This increases cloud droplet numbers, which in turn affects other cloud properties like liquid-water content and ultimately cloud albedo. These adjustm

Publikováno v: Atmospheric Chemistry and Physics, Vol 23, Pp 8749-8768 (2023)

Aerosol radiative forcing uncertainty affects estimates of climate sensitivity and limits model skill in terms of making climate projections. Efforts to improve the representations of physical processes in climate models, including extensive comparis

Source attribution of cloud condensation nuclei and their impact on stratocumulus clouds and radiation in the south-eastern Atlantic

Autor: H. Che, P. Stier, D. Watson-Parris, H. Gordon, L. Deaconu

Publikováno v: Atmospheric Chemistry and Physics, Vol 22, Pp 10789-10807 (2022)

The semi-permanent stratocumulus clouds over the south-eastern Atlantic Ocean (SEA) can act as an “air conditioner” to the regional and global climate system. The interaction of aerosols and clouds becomes important in this region and can lead to
