区域热辐射数据

区域热辐射数据库利用空间分辨率约1000米，重返周期为1天的遥感卫星图像反演出热辐射。一个区域在生产活动中需要消耗能量，热辐射强弱的变化能够反应这个区域生产经营活动的变化。本数据集将短时间内可重复观测整个地球表面的卫星遥感数据与地表城市一一映射，从而构建出了城市的热辐射指标。本数据集包括世界主要城市（包含中国336个地级市）的日度、月度、季度以及年度指标。

The Regional Thermal Radiation Database retrieves thermal radiation from remote sensing satellite images with a spatial resolution of approximately 1000 meters and a revisit period of 1 day. Energy is consumed during production activities in a region, and changes in thermal radiation intensity can reflect variations in the production and business operations of that region. This dataset establishes one-to-one correspondences between satellite remote sensing data capable of repeatedly observing the entire Earth’s surface within a short timeframe and urban areas, thereby constructing thermal radiation indicators for cities. This dataset includes daily, monthly, quarterly, and annual indicators for major cities worldwide, including 336 prefecture-level cities in China.
