Hydrometeor Classification of Winter Precipitation in Northern China Based on Multi-Platform Radar Observation System

Remote Sensing, 2021
Hydrometeor classification remains a challenge in winter precipitation cloud systems. To address this issue, 42 snowfall events were investigated based on a multi-platform radar observation system (i.e., X-band dual-polarization radar, Ka-band millimeter

Characteristics of Optical Properties and Heating Rates of Dust Aerosol over Taklimakan Desert and Tibetan Plateau in China Based on CALIPSO and SBDART

Remote Sensing, 2023
The spatial and temporal distributions of dust aerosol and its radiative heating effect over Taklimakan Desert (TD) and Tibetan Plateau (TP) were analyzed using the CALIPSO aerosol products and the SBDART model during 2007–2020.

Tropical deforestation causes large reductions in observed precipitation

Nature, 2023
A pan-tropical analysis using satellite, station-based and reanalysis datasets shows that deforestation causes reduced precipitation, and demonstrates that the effect increases with spatial scale. Tropical forests play a critical role in the hydrological

Effects of precipitation uncertainty on discharge calculations for main river basins [PDF]

, 2008
This study quantifies the uncertainty in discharge calculations caused by uncertainty in precipitation input for 294 river basins worldwide. Seven global gridded precipitation datasets are compared at river basin scale in terms of mean annual and ...

Changes in plant species richness distribution in Tibetan alpine grasslands under different precipitation scenarios [PDF]

, 2020
Species richness is the core of biodiversity-ecosystem functioning (BEF) research. Nevertheless, it is difficult to accurately predict changes in plant species richness under different climate scenarios, especially in alpine biomes.
