Table 3 Estimations of mean annual maximum wetland extent and standard deviation (in Mkm2 units) for global and three latitude zones from simulations based on seven soil moisture data, with the parameters calibrated against GIEMS-2, RFW, SWAMPS, and G2017 (denoted as SGIEMS-2, SRFW, SSWAMPS, and SG2017) respectively.
From: Gridded maps of wetlands dynamics over mid-low latitudes for 1980–2020 based on TOPMODEL
