基于风云四号卫星云图和ERA5与MERRA-2气象再分析资料的大尺度沙尘暴数据集

基于风云四号卫星云图和ERA5与MERRA-2气象再分析资料的大尺度沙尘暴数据集是根据气象卫星建立的一个大范围沙尘暴及相关天气信息数据库，可用于人工智能等领域的沙尘暴检测、沙尘暴预测等研究。数据库的数据主要来自中国最新的气象卫星风云四号（FY-4A），包含了可见光到长波红外的13个通道的卫星数据一级产品，以及沙尘检测的二级产品。另外，根据经纬度匹配在数据库中添加了气温、海平面气压等再分析数据作为沙尘暴产生和运动的天气资料。数据库以HDF（Hierarchical Data Format）的格式存储，每15分钟存储一个HDF文件。数据库另外包含一个注明时间、索引、文件路径的CSV文件。

The large-scale dust storm dataset, built upon FY-4 satellite cloud imagery and ERA5 and MERRA-2 meteorological reanalysis data, is a comprehensive database of large-scale dust storms and associated meteorological information established using meteorological satellite data. It can be applied to research such as dust storm detection and prediction in fields including artificial intelligence and other relevant domains. The data of this database primarily comes from China's latest meteorological satellite FY-4A, encompassing Level-1 products of satellite data across 13 channels spanning from visible light to long-wave infrared, as well as Level-2 products for dust detection. Additionally, reanalysis datasets including air temperature and sea level pressure are incorporated into the database through longitude-latitude matching, providing meteorological support for studying the generation and propagation of dust storms. The database is stored in HDF (Hierarchical Data Format) format, with one HDF file saved every 15 minutes. Furthermore, the database includes a CSV file that records timestamps, indices and corresponding file paths.
