EOWetMet: Pan-Arctic Average Wetland Methane Flux Dataset (2015-2024)

The EOWetMet Pan-Arctic Average Wetland Methane Flux Dataset provides period-average methane flux maps for northern and Arctic wetlands derived from the products developed within the EOWetMet Database. The dataset is intended to support rapid visualization, comparison, and assessment of large-scale methane emission patterns across the pan-Arctic domain. The dataset includes average methane flux products derived from the EOWetMet Random Forest methane upscaling framework using four wetland and land-cover map configurations: PAWM, BAWLD, WAD2M, and MODIS IGBP. The 9 km products summarize the daily methane flux dataset, while the 500 m products summarize the monthly methane flux dataset. All EOWetMet summary products represent averages computed over the full 2015-2024 study period. The repository also includes benchmark average methane products derived from CarbonTracker and the WetCHARTs ensemble at their native spatial resolutions. These benchmark products represent averages computed over the full temporal coverage available from their respective source datasets (2015-2023 for CarbonTracker and 2015-2022 for WetCHARTs). The products are provided to facilitate comparison between EOWetMet methane flux estimates and widely used top-down and bottom-up methane emission datasets.
