Downward Shortwave Radiation (DSR) refers to the portion of solar radiation at the top of the atmosphere (TOA) that finally reaches the Earth's surface after undergoing multiple absorption and scattering processes by atmospheric gases, clouds, aerosols and other substances. It is the primary energy source for the biosphere and biogeochemical cycles, and plays a critical role in accurately simulating processes such as vegetation photosynthesis, surface-atmosphere sensible/latent heat exchange, and the water cycle.

Solar Energy Monitoring: Downward shortwave radiation products can be applied to climate resource surveys, forestry development planning, as well as guiding agricultural production, management and planting.

Photovoltaic Power Generation Assessment: As baseline data, it enables scientific evaluation of photovoltaic power generation potential and supports early-stage site selection decision-making for photovoltaic power station construction, thereby providing a basis for clean energy development planning.

Evapotranspiration: It provides multi-spatiotemporal-scale driving data for remote sensing monitoring and estimation of soil evaporation and plant transpiration.

Carbon Stock Survey: Based on different vegetation types, as well as soil, atmospheric, hydrological and climatic conditions, it analyzes vegetation carbon sequestration capacity and carbon stock status, providing support for the carbon peak and carbon neutrality strategies and decision-making.
