Deep Convective Systems (DCSs) reaching scales of 100-1000 km play a pivotal role as the primary precipitation source in the tropics. Those systems can have large cloud shields, and thus not only affect severe precipitation patterns but als...
Dynamic calibration of low-cost PM2.5 sensors using trust-based consensus mechanisms [0.03%]
基于信任的共识机制下的低成本PM2.5传感器动态校准研究
Sachit Mahajan,Dirk Helbing
Sachit Mahajan
Low-cost particulate matter (PM) sensors enable high-resolution urban air quality monitoring but face challenges from offsets, scaling mismatches, and drift. We propose an adaptive trust-based calibration framework that first corrects syste...
Photochemistry of iron-containing secondary organic aerosol is impacted by relative humidity during formation [0.03%]
相对湿度影响含铁二次有机气溶胶生成过程中的光化学反应
Natasha M Garner,Fabian Mahrt,Jens Top et al.
Natasha M Garner et al.
Secondary organic aerosol (SOA) comprises most of the submicron atmospheric particle mass, and often becomes internally mixed with other particles. When SOA mixes with transition metal (e.g., iron) containing particles, metal-organic comple...
Finer resolutions and targeted process representations in earth system models improve hydrologic projections and hydroclimate impacts [0.03%]
地球系统模型中更精细的分辨率和有针对性的过程表征改善了水文预测和水文气候影响
Puja Das,Auroop R Ganguly
Puja Das
Earth system models inform water policy and interventions, but knowledge gaps in hydrologic representations limit the credibility of projections and impacts assessments. The literature does not provide conclusive evidence that incorporating...
A 2°C warming can double the frequency of extreme summer downpours in the Alps [0.03%]
《2摄氏度的升温可使阿尔卑斯山地区夏季暴雨频次增加一倍》

Nadav Peleg
Intense short-duration summer rainfall in mountainous areas can trigger a variety of natural hazards, including flash floods, debris flows, and urban floods. Warming is expected to intensify extreme sub-hourly rainfall events in response to...
Aircraft emissions of ultrafine particles characterized by real-world near runway measurements [0.03%]
基于机场现场连续观测的飞机尾气超细颗粒物排放特征研究

Jeff Maes et al.
Aircraft emissions of (ultra)fine particles during landing and take-off operations pose increasing human health hazards for airport employees and near-airport communities. Measurements of in-operation aircraft are therefore crucial for char...

Rocket emissions thin the stratospheric ozone layer. To understand if significant ozone losses could occur as the launch industry grows, we examine two scenarios. Our 'ambitious' scenario (2040 launches/year) yields a -0.29% depletion in an...
Disentangling density and geometry in weather regime dimensions using stochastic twins [0.03%]
基于随机配对方法揭示天气型的几何与密度特性

Paul Platzer
Large-scale atmospheric variability can be summarized by recurring patterns called weather regimes. Their properties, including predictability, have been studied using the local dimension, a geometrical estimate of degrees of freedom from m...
Impact of water vapor on stratospheric temperature after the 2022 Hunga Tonga eruption: direct radiative cooling versus indirect warming by facilitating large particle formation [0.03%]
2022年洪加汤加火山喷发后水蒸气对平流层温度的影响:直接辐射冷却与通过促进大粒子形成而产生的间接变暖效应
Xi Chen,Jun Wang,Meng Zhou et al.
Xi Chen et al.
The unprecedented water vapor amount (WV, 150-160 Tg) injected by the 2022 eruption of Hunga Tonga-Hunga Ha'apai not only directly cooled the stratosphere, but also facilitated the formation and growth of sulfate particles, indirectly heati...
Disentangling anthropogenic and dynamic contributions to recent ocean warming [0.03%]
解开近期海洋变暖中的人为因素与动力学因素的贡献关系
Jiheun Lee,Rémi Tailleux,Till Kuhlbrodt
Jiheun Lee
As the ocean absorbs over 90% of excess radiative heat, recent ocean warming is shaped by a combination of anthropogenic surface heat gain and dynamical processes redistributing heat. To distinguish these contributions, we introduce a novel...
