Small bias, large errors: a dual-perspective evaluation of numerical model near-surface wind direction over beijing megacity

Abstract Accurate surface wind fields are essential for understanding moisture transport and heavy rainfall forecasts, yet the ability of kilometer-scale numerical models to capture wind direction over heterogeneous surfaces remains poorly quantified. Using the EARS1km reanalysis...

Seasonally Regionalized Interdecadal Decrease in Extreme Precipitation Over the Tropical Indo‐Western Pacific Region Around 2008/2009

Abstract Increase in extreme precipitation is expected with global warming that leads to an increase in atmospheric moisture content. Here, we present evidence for interdecadal decrease in extreme precipitation frequency and amount around 2008/2009 over the tropical Indo‐western...

UAV-Satellite Integration Reveals Continuous Methane Emission Variability from Chinese Coal Mine Ventilation Shafts

Abstract Satellite quantification of coal mine methane lacks validation for continuously operating ventilation systems with high temporal variability. We integrate 75 unmanned aerial vehicle (UAV) flights (30 successful, 13 days) with 6.5 years of satellite observations at a Chin...

Hierarchical ecohydrological controls on drought-driven ecosystem stability in alpine and temperate grasslands across the Qinghai–Tibetan and Mongolian plateaus

Study region This study examines alpine and temperate grasslands across the Qinghai–Tibetan Plateau (TP) and the Mongolian Plateau (MP) during 2001–2023, representing two contrasting hydroclimatic settings in Asia. Study focus This study aims to compare drought regimes, drought-r...

Improved representation of isoprene-derived secondary organic aerosol in CAM6-Chem reveals regional contrasts in its long-term changes over China

Abstract. Isoprene-derived secondary organic aerosol (ISOA) is an important component of atmospheric organic aerosol, but its formation remains incompletely represented in global chemical models, creating uncertainty in ISOA changes and their drivers. In this study, we updated th...

Performance Evaluation of IMERG and GSMaP Hourly Precipitation Products for Landfalling Typhoon Rainfall in China

This study systematically evaluates the performance of GPM_IMERG and GSMaP_Gauge hourly precipitation products in typhoon rainfall over Mainland China. Using hourly gauge observations from the China Meteorological Administration (CMA)’s national basic meteorological stations as r...
