Abstract Static volatile organic compound (VOC) rankings can identify abundant or reactive compounds, but their ozone relevance depends on the meteorological and photochemical state during ozone production. Here we combine yearlong hourly observations of speciated VOCs in urban B...

Six-fold reduction in ocean heat content estimate uncertainty since 1960
Abstract Ocean heat content (OHC) dominates Earth’s energy imbalance, but its uncertainty has not been fully understood. Here, we construct a Large-Ensemble to comprehensively quantify the OHC uncertainty from global to regional scales since 1955, and consider eight groups of err...

Global rice methane emissions tripled over six decades amid declining emission intensity
Abstract Rice paddies are among the largest anthropogenic sources of methane (CH4), yet substantial uncertainties persist in the long-term magnitude and spatiotemporal dynamics of the emissions. Here we show a spatially explicit global estimate of rice CH4 emissions from 1961 to...

Recent globally synchronous seasonal warm events unprecedented since 850 CE
Spatially synchronous extreme warm events can amplify environmental and societal impacts by affecting multiple regions simultaneously. However, previous studies have largely focused on June–August (JJA) events during the instrumental period, limiting understanding of their season...

Abstract Near‐surface wind speed (NSWS) regulates the intensity of land‐atmosphere fluxes and the viability of wind energy systems, playing a pivotal role in human adaptation to climate change. However, at the current stage, global climate models exhibit a wide inter‐model spread...

Abstract. With global sulfur emissions declining and concurrent marine iodine emissions rising, new particle formation (NPF) driven by iodic acid (HIO3) and iodous acid (HIO2) has become critical to global aerosol and cloud condensation nuclei (CCN) budget. However, the role of u...

Abstract. The interior of the Tibetan Plateau exerts a first-order influence on the Asian monsoon and regional climate, yet vertically resolved aerosol observations there are scarce, and no openly archived, multi-year, ground-based profile record has existed for this exceptionall...

Abstract Extreme precipitation has increased over many regions in recent decades, but the simulation and projection remain particularly challenging over complex terrains, such as the Tibetan Plateau (TP). Here, we investigate the future changes in precipitation extremes and persi...

Changes in the tropical rainfall seasonal cycle dominated by mesoscale convective systems
Global warming is reorganizing atmospheric circulation and hydroclimate, and tropical rainfall is a key manifestation of this response. Yet how these large-scale changes are translated into the tropical rainfall seasonal cycle remains uncertain because organized convection, which...

Abstract. The three-dimensional unstructured-mesh finite-element atmospheric dynamical framework is gaining significance owing to its flexibility in representing complex topography and capability for multi-scale simulations in high resolutions. However, this framework has substan...

ABSTRACT The anomalous summer melting of the Greenland Ice Sheet (GrIS) is one of the key signals of ongoing climate system changes. The complex spatiotemporal characteristics of GrIS and its impacts on global sea‐level rise have attracted increasing attention. Although previous...

Sodium Lidar observed multiple sodium layer structures and their dynamical coupling mechanism
Abstract. On the night of 13 June 2013, the University of Science and Technology of China (USTC) sodium lidar observed multiple sporadic sodium layers (SSLs) and enhanced sodium patterns (ESPs) over Hefei, China (31.8°N, 117.3°E). These structures appeared at different times, col...

Increasing Climate Constraint on Vegetation Productivity Under Rising CO 2 in Northeast Asia
Abstract Elevated atmospheric CO 2 enhances vegetation productivity through direct physiological and indirect climate‐mediated pathways. However, how the balance between these mechanisms evolves under continued CO 2 rise remains unclear. Here, we use CMIP6 Earth system models to...

Abstract Biomass burning (BB) is a major global sources of ozone (O 3 ) precursors, including nitrogen oxides (NO x ), carbon monoxide (CO), and volatile organic compounds (VOCs). Here, we combine Community Earth System Model 1 with airborne measurements from the NASA Atmospheric...

Abstract. Inconsistent changes in precipitation and flooding have spurred investigations into the underlying mechanisms, yet the quantitative understanding of interactions between precipitation, temperature, and land cover in streamflow dynamics remains limited. We investigate st...

Digital twin for city traffic emissions using deep vision and real time monitoring
Urban on-road air pollution remains a pervasive threat to public health, yet its management is fundamentally constrained by a lack of spatiotemporal precision in emission inventories. Conventional inventories rely on static, registration-based proxies that fail to capture the hig...

Advancing boundary-layer physics via Doppler wind LiDAR dynamic-thermodynamic profiling
Simultaneous, high-resolution measurements of boundary-layer dynamics and thermodynamics remain a longstanding observational challenge. We present a Doppler wind LiDAR–based retrieval that derives virtual potential temperature from TKE-budget buoyancy residuals, enabling concurre...
