Major TOM Core VIIRS Nighttime Light数据集是一个基于可见光红外成像辐射计套件（VIIRS）日/夜波段（DNB）的年度辐射合成数据集，按照Major TOM网格进行组织。该数据集专注于地球观测、遥感和地理空间分析，特别是夜间灯光数据。数据集包含从2016年到2024年的全球数据，总共有2,108,341个补丁，每个补丁大小为1056×1056像素（分辨率为10米），总像素数超过2.3万亿。主要变量为median，表示年度辐射中值，单位为nW/cm²/sr，并计划未来提供其他模态数据（如平均值、最大值等）。空间覆盖范围从纬度75°N到65°S，经度180°W到180°E，使用Major TOM 10米网格，几乎每个陆地补丁每年至少出现一次，仅有少量重叠。数据集以Cloud Optimized ZIP（cozip）格式发布，支持通过HTTP范围请求高效获取单个补丁，无需下载整个分片。The Major TOM Core VIIRS Nighttime Light dataset consists of annual radiance composites from the Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB), packaged on the Major TOM grid. It focuses on earth observation, remote sensing, and geospatial analysis, particularly nighttime light data. The dataset spans from 2016 to 2024, with a total of 2,108,341 patches, each of size 1056×1056 pixels (10-meter resolution), and over 2.3 trillion total pixels. The primary variable is median, representing the median annual radiance in units of nW/cm²/sr, with additional modalities (e.g., average, max) planned for future release. Spatial coverage is global, using the Major TOM 10-meter grid, approximately from 75°N to 65°S latitude and full 180°W to 180°E longitude, with nearly every land patch included at least once per year and minimal overlaps. The dataset is published in Cloud Optimized ZIP (cozip) format, enabling efficient access to individual patches via HTTP range requests without downloading entire shards.
