Description

The Global Inundation Extent from Multi-Satellites-MethaneCentric (GIEMS-MC) provides two harmonized times series maps at 0.25°x0.25° and monthly time step of wetland surfaces from 1992 to 2020: one representing inundated and saturated wetlands, and the other covering all wetlands, including peatlands. In addition, GIEMS-MC provides consistent 0.25°x0.25° maps of rice paddies (from MIRCA2000) and open permanent water categories (from GLWDv2) used in its production. Information on the dominant vegetation type and wetland type per pixel is also provided.

GIEMS-MC v1.1 is the version used in related publication :

Sci. Data, 17, 2985–3008, https://doi.org/10.5194/essd-17-2985-2025, 2025. 

The differences between GIEMS-MC v1.1 and v1.0 are minor. These include the inclusion of Deltas in ancillary information and the correction of typos.
