On March 28, 2023, the rating results of "Top Ten Progresses in Meteorological Science and Technology in China" were announced. "C-Coupler3 for Earth System Numerical Prediction", an achievement completed under the leadership of Professor Liu Li’s Research Group from the Department of Earth System Science (DESS), Tsinghua University was selected.The rating, led by the National Alliance for Int...
Electric power, the largest coal consumption sector in China, emits a large amount of carbon dioxide and air pollutants. The health risks incurred by coal-fired power pollution emissions cannot be ignored, and carbon dioxide emissions are always at a high level although a series of policies such as the elimination of backward production capacity, ultra-low emission transition and energy saving ...
Central Africa, boasting the second largest tropical moist forests and a large area of savannas, plays an important role in the global terrestrial ecosystem carbon cycle. Over the past few decades, however, deforestation and degradation in this region have produced a lot of carbon emissions, but at the same time, vegetation growth and restoration will give rise to carbon sequestration, so the d...
The solar photovoltaics (PV) industry has grown rapidly, raising very high requirements on high-quality solar radiation data (including total radiation data and Rdir and Rdif component data). Satellite-based remote sensing data inversion is the main means to obtain total radiation data. However, due to the inhomogeneity of time series caused by satellite replacement and technical iteration, the...
Plants absorb CO2 from the atmosphere through their canopy via process of photosynthesis, forming gross primary productivity (GPP), which plays an important role in realizing terrestrial ecosystem carbon sequestration and “carbon neutrality”. The changes of GPP is regulated by environmental changes via the physiological and structural properties of canopies (such as vegetation greenness). The...
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...
