Global Peatland Fractional Coverage¶
Peatlands, as waterlogged terrestrial wetland ecosystems, store vast amounts of soil carbon and freshwater, playing a crucial role in the global carbon and hydrologic cycles. The Peat-ML dataset is a spatially continuous global map of peatland fractional coverage generated using machine learning models trained with climate, geomorphological, soil data, and remotely-sensed vegetation indices. Available peatland coverage maps from 14 regions, along with non-peatland ecoregions, were used to develop a statistical model with an average r-squared of 0.73 and errors of 9.11% (root mean square) and -0.36% (bias). The dataset is available in NetCDF format and published in 2021. For more information, you can access the associated research paper here.
The original datasets are available as NetCDF with a model accuracy with R² = 0.73, RMSE = 9.11%, MBE = -0.36%. You can download the Peat-ML Dataset (2021) here. Additional details are available in the paper Melton et al., 2022
