### Analysis of the Distribution of Articles among Journals and Research Areas  
We found a total of 45,673 publications referencing EO satellite data that had been published in 1895 journals (Table S1). However, as shown in Table 1, more than half of all journals (1239) have published no more than five articles that reference the use of satellite data, and 678 journals have published only one paper. Only 13 journals were found to have published more than 500 articles referencing EO satellites; a total of 19,999 articles have been published in these journals and account for 43.79% of the total. Only 67 journals have published more than 100 papers. In terms of the number of published papers, the top 10 journals were found to be Remote Sensing (4627), the International Journal of Remote Sensing (4038), Remote Sensing of Environment (3443), IEEE Transactions on Geoscience and Remote Sensing (1491), the Journal of Geophysical Research: Atmospheres (953), IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing (920), the International Journal of Applied Earth Observation and Geoinformation (853), Photogrammetric Engineering and Remote Sensing (808), the ISPRS Journal of Photogrammetry and Remote Sensing (636), and the Journal of Applied Remote Sensing (636). Most of these journals serve one or more parts of the remote sensing and EO community. Some publish documents, reports, codes, and informational articles on photogrammetry, spatial information systems, computer vision, imaging sciences, etc.  
Among the journals involved in different EO satellites, similar journals have published a large number of articles (most of these journals have published a small number of articles referencing EO satellite data). Some journals have become the focus for articles referencing EO satellite data, these include Remote Sensing, the International Journal of Remote Sensing, and Remote Sensing of Environment. These journals have published high-quality papers that promote the application of EO satellite data, thus improving the understanding of the application of EO satellite data to Earth system science and sustainable development (Table S1).  
As shown in Table S1, the United States is the most important host country for the top 13 journals referencing EO satellite data. This means that the United States provides a significant support for remote sensing applications and thus for promoting an understanding of the Earth and its environment. From the percentages of articles referencing EO satellite data, it can be seen that EO satellites have gradually become an essential foundation of the research carried out by the remote sensing and Earth science communities, and Remote Sensing, the International Journal of Remote Sensing, and Remote Sensing of Environment significantly contribute to the application of EO satellite data.  
The main research disciplines to which the papers referencing EO satellites were related were obtained from the WoS website (Table S2). The WoS schema comprises  
\begin{table}
\begin{tabular}{c c c c} \hline \hline
**Number of Articles Per Journal** & **Number of Journals** & **Number of Articles** & **Percentage of the Number of Articles (\%)** \\ \hline

Table 1: Classification of journals by the number of articles referencing EO satellites.  
252 subjects such as science, social sciences, and arts and humanities. The most significant research areas included remote sensing (20,998), imaging science photographic technology (18,066), environmental sciences ecology (17,408), and geology (12,290) for each of which there were more than 10,000 publications.
