Against the backdrops of global warming, the overall warming and wetting of the Tibetan Plateau (TP) has led to the increase of land evapotranspiration and the adjustment of surface energy budget. What are impacts of these surface energy changes on precipitation? To address the above question, Yang Kun's Research Group of the Department of Earth System Science (DESS), Tsinghua University analyz...
Soils store four times as much carbon as vegetation. Loss of soil organic carbon may accelerate global warming, whereas promoting soil carbon storage to sequester more carbon dioxide (CO2) as soil organic carbon can help mitigate climate change. A recent research led by Tsinghua University and Cornell University revealed that microorganisms are by far the most influential factor in soil carbon ...
Mangroves, as one of the ecosystems with the highest soil carbon density and carbon fixation rate in the world, have extremely high value for ecological service. Affected by human activities, the mangrove area is rapidly decreasing at a rate of 1-2% per year. In order to restore the ecological function of mangroves, China and many other countries have carried out a large number of ecological re...
How well can current mainstream LSMs simulate the global land-atmosphere interaction? Here’s some information~ Among Earth system models, the simulation ability of land surface models (LSMs) on global land-atmosphere interaction significantly affects the accuracy of weather and climate forecast. However, due to the lack of global observation data, it is difficult to evaluate the simulation a...
The National Tibetan Plateau Data Center, as a research paper relational database, has recently published “A global daily soil moisture dataset derived from Chinese FengYun-3B Microwave Radiation Imager (MWRI) (2010–2019) (https://doi.org/10.11888/Terre.tpdc.271954) co-developed by Associate Professor Lu Hui’s team of the Department of Earth System Science (DESS), Tsinghua University and Res...
The National Tibetan Plateau Data Center of China, as a research paper related data warehouse, has recently published “A long-term (1979-2020) high-resolution (1/30°) precipitation dataset for the Third Polar region (TPHiPr)” developed by Professor Yang Kun’s Research Group of Tsinghua University. The related article titled “TPHiPr: a long-term (1979–2020) high-accuracy precipitation datas...
The eastern Tibetan Plateau is rich in soil organic matter (SOM), which increases the amount of water the soil can hold while decreasing the rate at which heat moves through it. Previous studies have mostly discussed the impact of SOM on soil hydrothermal state from the perspective of soil thermal properties based on land surface process model, but how the plateau SOM influences the coupled lan...
With the increasing shortage of fossil energy and air pollution, solar energy sees its rapid development as a clean and renewable energy. Developing and utilizing solar energy is one of the important ways to achieve the goals of “carbon neutrality and carbon peaking” in China. Seasonal extremely low solar radiation events seriously threaten the stability of photovoltaic power generation sys...
