Cropland is a foundation for human survival and development. Accurate, detailed, and up-to-date information on cropland extent is crucial for accurate agricultural layout, and the assessment of food security. However, due to the lack of accuracy, robustness and transferability in traditional cropland mapping methods, it remains challenging to monitor cropland dynamics at high spatial and tempor...
A long term global daily soil moisture dataset derived from AMSR-E and AMSR2 released by the National Tibetan Plateau Data Center (TPDC) (https://data.tpdc.ac.cn) has recently realized near-real-time daily updating. The current product can provide global daily soil moisture data two days after the passage of a satellite.Based on AMSR-E/AMSR 2 Brightness Temperature (TB), this product uses a com...
Many economies set climate mitigation targets for 2020 at the 2009 15th Conference of the Parties conference of the United Nations Framework Convention on Climate Change in Copenhagen (COP15), which has become an important milestone in the global climate mitigation actions. How to track the completion of climate mitigation targets in countries around the world and analyze the climate mitigation...
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...
