Retrieval of dominant methane (CH4) emission sources, the first high resolution(1-2m) dataset of storage tank in China in 2021

We presented a storage tank inventory of 92 typical cities with high volatile organic compounds, in response to the Three-Year Action Plan for Winning the Blue Sky Defense War, proposed by the State Council of China. It comprises of 14461 storage tanks, which are extracted based on high spatail resolution images of GaoFen-1, GaoFen-2, GaoFen-6, and Ziyuan satellites in year of 2021. It is the first inventory covering detailed distribution locations and boundaries of storage tanks. The inventory we aim to share provides a basic distribution of storage tanks in different sizes and will contribute to support environmentally friendly regulations proposal for more effective pollution control and energy resource management.

The uploaded dataset is created in ArcGIS 10.8.2 platform, and stored in the format of shapefile (.shp). In the attributes tables of the .shp files, the field, AreaOT_m2, stands for the area of a storage tank in square meters; and the two fields, Year_1 and Year_2, represent the years before and after the construction of the storage tank respectively.
