Impact of Amazonian deforestation on precipitation reverses between seasons - Nature
Abstract Tropical deforestation was found to cause large reductions in precipitation using a range of observation-based datasets1. However, the limitations of satellite-based space-for-time statistical analysis have hindered understanding of the roles of reshaped mesoscale atmospheric circulation and regional precipitation recycling at different scales.
Asymmetric sensitivity of boreal forest resilience to forest gain and loss - Nature Ecology & Evolution
Abstract Forest gains and losses may have unequal effects on forest resilience, particularly given their distinct temporal dynamics. Here, we quantify the sensitivities of boreal forest resilience to forest cover gain and loss using a resilience indicator derived from the temporal autocorrelation (TAC) of the kernel normalized difference vegetation index from 2000 to 2020.
Small reduction in land surface albedo due to solar panel expansion worldwide - Communications Earth & Environment
Abstract Photovoltaic (PV) panel deployment for decarbonization may reduce local terrestrial albedo, triggering a positive radiative forcing that counteracts the desired negative radiative forcing from carbon emission reductions. Yet, this potential adverse impact remains uncertain due to limited observations at PV sites. Herein we employ a robust linear parameterization method to quantify PV-induced albedo changes based on satellite data globally.
Urgent need to improve modelled sensitivity of evaporation to vegetation change - Nature Water
Earth system model projections of vegetation–climate feedback frequently depend on inaccurate values of evaporation sensitivity to vegetation changes, potentially resulting in misleading conclusions. A promising avenue involves improving the transpiration partitioning parameterizations and incorporating groundwater connections to refine the modelled sensitivity.

Long-term gridded land evapotranspiration reconstruction using Deep Forest with high generalizability - Scientific Data
Abstract Previous datasets have limitations in generalizing evapotranspiration (ET) across various land cover types due to the scarcity and spatial heterogeneity of observations, along with the incomplete understanding of underlying physical mechanisms as a deeper contributing factor. To fill in these gaps, here we developed a global Highly Generalized Land (HG-Land) ET dataset at 0.5° spatial resolution with monthly values covering the satellite era (1982–2018).
A global-scale framework for hydropower development incorporating strict environmental constraints - Nature Water
Discharge dataset Our estimate of hydropower potential using the 38-year (1979–2016) global discharge dataset from the Terrestrial Hydrology Research Group at Princeton University21 contains discharge information on 2.89 million rivers globally. This dataset vectorizes the global river network using the latest global high-resolution MERIT DEM49,50 (3'' resolution), producing modelled river routes consistent with satellite-based information.
Two-Tier Synergic Governance of Greenhouse Gas Emissions and Air Pollution in China’s Megacity, Shenzhen: Impact Evaluation and Policy Implication
Synopsis Transdepartment and transregional cooperation to facilitate a two-tier synergic governance of GHG emissions and air pollution in megacities. 1.
Deforestation-induced warming over tropical mountain regions regulated by elevation
Abstract Agriculture is expanding in tropical mountainous areas, yet its climatic effect is poorly understood. Here, we investigate how elevation regulates the biophysical climate impacts of deforestation over tropical mountainous areas by integrating satellite-observed forest cover changes into a high-resolution land–atmosphere coupled model.
Searching high efficiency and environmentally benign leaching reagent for ion-adsorption rare earth based on the zeta potential of clay particles
To overcome the serious water pollution and landslides that occur in response to in situ ion-adsorption rare earth (IARE) leaching, it is essential to identify highly efficient and environmentally benign leaching reagents. Therefore, the leaching efficiency (LE) of IARE by different inorganic electrolytes at different concentrations was compared, and the landslide and ion releasing performance of tailings driven by water rinsing were evaluated based on the zeta potential of clay particles (CPs).
