Evaluation of the simulated interannual variabilities of wetland extent against wetland calibration data at basin scale. Interannual variability in wetland area from GIEMS-2, WAD2M, and simulations based on SM from NCEP-DOE, MERRA-2, ERA5, and GLDAS-Noah v2.0 for Hudson Bay lowlands, Amazon basin, Congo basin, and West Siberian lowlands for the period 1980–2020, with the parameters calibrated with GIEMS-2 and WAD2M (denoted as SGIEMS-2 and SWAD2M), respectively. The spatial locations of the four wetland hotspots are shown in Fig. 1. For GLDAS-Noah v2.0, the time period only covers 1980–2014.
