Accurate offshore surface wind forecasting is crucial for navigation safety and disaster prevention. Sea surface roughness is a key factor affecting offshore windsite forecasting. However, significant biases exist in forecasting sea surface winds due to the uncertainties in estimating sea surface roughness. However , traditional methods for calculating sea surface roughness, which primarily rel...
Accurate precipitation forecast, especially heavy precipitation forecast, is challenging in weather forecasts. Heavy precipitation always brings about flash floods, urban waterlogging, heavy snow, and other disasters, making it imperative to improve the forecast performance of precipitation, especially heavy precipitation. Certain bias is still found in current precipitation forecast. For examp...
Population dynamics profoundly shape societal development and economic growth. The size and composition, through the population consumption and production trends, are correlated with multiple societal issues. As cities are the fundamental units for decision-making processes, city-level population data is vital for policy makers in areas of urban planning, shrinking cities, GHG emission projecti...
Accurate and reliable l land use/land cover (LULC) data are typically utilized as a crucial basis for research on resource management and ecological and environmental evaluation. Land resource surveys and remote sensing are main methods for understanding and grasping LULC changes. However, current LULC products lack updates and do not have sufficient access to finer-scale land survey statistics...
Recently, Professor Bai Yuqi’s team of the Department of Earth System Science (DESS), Tsinghua University and Researcher Li Fang’s team from the Institute of Atmospheric Physics (IAP), Chinese Academy of Sciences have jointly completed the research on the regional health effect of landscape fire emissions in China during 2021-2100. Based on the projected future population and landscape fire s...
On November 19, the 2023 China Report of the Lancet Countdown on Health and Climate Change (China Report) was launched in Beijing. This report was authored by 76 experts from 26 major institutions both domestically and internationally, led by the Lancet Countdown Regional Centre for Asia based in the Department of Earth System Science at Tsinghua University. The Vice President of Tsinghua Unive...
Land surface process is a key process in Earth’s surface system, and accurate estimation of land surface state plays an important role in improving the performance of an Earth system model. The Land surface data assimilation system improves the observability and predictability of land surface state variables by integrating the advantages of multi-source Earth observation data and land surface ...
China has been plagued by floods in history, where the flood losses account for about 10% of the world. In recent years, under the impact of climate change, extreme weather events such as heavy rainstorms and severe precipitation have occurred frequently, increasing the frequency and intensity of fluvial floods. Meanwhile, as China and other other developing countries undergo rapid urbanization...
