Abstract The annual mean Surface Air Temperature (SAT) observed during 1757–1762 in central Beijing was 3.1°C lower than that of the nearby Autonomous Weather Stations (AWS) in recent 6 years (2015–2020). The change was much larger than the averaged global warming of the past cen...

Deciphering riverine CODMn sources: driver identification and carbon cycle impacts
The large-scale monitoring of riverine organic pollution is of significant practical importance for river basin ecological management and sustainable development to replace the traditional monitoring stations. The development for remote sensing of riverine chemical oxygen demand...
