TLDR
Wang et al. as mentioned in this paper developed the global Wetland Area and Dynamics for Methane Modeling (WAD2M) version 1.0 dataset, which combines a time series of surface inundation based on active and passive microwave remote sensing at a coarse-resolution with six static datasets that discriminate inland waters, agriculture, shoreline, and non-inundated wetlands.Abstract:
. Seasonal and interannual variations in global wetland
area are a strong driver of fluctuations in global methane (CH 4 )
emissions. Current maps of global wetland extent vary in their wetland
definition, causing substantial disagreement between and large uncertainty in
estimates of wetland methane emissions. To reconcile these differences for
large-scale wetland CH 4 modeling, we developed the global Wetland Area
and Dynamics for Methane Modeling (WAD2M) version 1.0 dataset at a
∼ 25 km resolution at the Equator (0.25 ∘ ) at a
monthly time step for 2000–2018. WAD2M combines a time series of surface
inundation based on active and passive microwave remote sensing at a coarse
resolution with six static datasets that discriminate inland waters,
agriculture, shoreline, and non-inundated wetlands. We excluded all
permanent water bodies (e.g., lakes, ponds, rivers, and reservoirs), coastal
wetlands (e.g., mangroves and sea grasses), and rice paddies to only
represent spatiotemporal patterns of inundated and non-inundated vegetated
wetlands. Globally, WAD2M estimates the long-term maximum wetland area at
13.0×106 km 2 (13.0 Mkm 2 ), which can be divided into three
categories: mean annual minimum of inundated and non-inundated wetlands at
3.5 Mkm 2 , seasonally inundated wetlands at 4.0 Mkm 2 (mean annual
maximum minus mean annual minimum), and intermittently inundated wetlands at
5.5 Mkm 2 (long-term maximum minus mean annual maximum). WAD2M shows
good spatial agreements with independent wetland inventories for major
wetland complexes, i.e., the Amazon Basin lowlands and West Siberian
lowlands, with Cohen's kappa coefficient of 0.54 and 0.70 respectively among
multiple wetland products. By evaluating the temporal variation in WAD2M
against modeled prognostic inundation (i.e., TOPMODEL) and satellite
observations of inundation and soil moisture, we show that it adequately
represents interannual variation as well as the effect of El
Nino–Southern Oscillation on global wetland extent. This wetland extent
dataset will improve estimates of wetland CH 4 fluxes for global-scale
land surface modeling. The dataset can be found at https://doi.org/10.5281/zenodo.3998454 (Zhang et al., 2020).read more

TL;DR: In this article, the authors present a metadata analysis of methane fluxes from all major natural, impacted and human-made aquatic ecosystems and conclude that aquatic emissions will probably increase due to urbanization, eutrophication and positive climate feedbacks.
