a Surface water body frequency map in 2016 for China, and (1, 2, 3) are its three zoom-in views for Qinghai Lake, Poyang Lake, and Taihu Lake, respectively. b The 28-year surface water body frequency map during 1989–2016. c Water body areas within China during 1989–2016 with different annual water frequencies. The permanent water body areas from the Joint Research Centre (JRC) data set2 during 1989–2015 are also shown.
