Correction: Min, S., et al. Recent Ground Subsidence in the North China Plain, China, Revealed by Sentinel-1A Datasets. Remote Sensing 2020, 12, 3579

The authors wish to make the following corrections to this paper [1]:

In the original article, there was a mistake in Figure 3 as published. During the review process, the reviewer recommends using the percentages of the changes to replace the specific number changes of the area of subsidence exceeding 50 mm among the three sub-plains (Section 4.1, Paragraph 2). Therefore, we revised the relevant text based on the reviewer’s suggestion. Moreover, the specific number changes are shown by Figure 3c. However, due to our negligence, Figure 3c did not use the latest version in the online version. And which leads to the difference between the area of subsidence exceeding 50 mm in Figure 3c and the area of subsidence exceeding 50 mm in Paragraph 2 (Section 4.1). To avoid misunderstanding, we intend to revise Figure 3. The corrected Figure 3 appears below. The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.
