LSDSSIMR: Large-Scale Dust Storm Database Based on Satellite Images and Meteorological Reanalysis Data

In recent years, dust storms have occurred frequently, significantly affecting people's daily lives. Therefore, the detection, monitoring, and early warning of dust storms have a great social significance. Previous methods have mainly been based on atmospheric motion to build physical models for weather forecasting. Although there are many meteorological applications based on deep learning, to the best of authors' knowledge, there is no dust storm database with a high spatiotemporal resolution, which is essential for deep learning methods. Since meteorological satellites can observe the Earth's atmosphere from a spatial perspective at a large scale, in this article, a dust storm database is constructed using multichannel and dust label data from the Fengyun-4 A geosynchronous orbiting satellite, namely the large-scale dust storm database based on satellite images and meteorological reanalysis data (LSDSSIMR), with a temporal resolution of 15 min and a spatial resolution of 4 km from March to May of each year during 2020–2022. Meteorological reanalysis data are added to LSDSSIMR for spatiotemporal prediction methods. Each data file is stored in an HDF5 format, and the final LSDSSIMR contains nearly 5400 HDF5 files. Moreover, some traditional dust detection methods based on spectral analysis are executed as a benchmark.
