How much methane the world's wetlands release (monthly)

CMS: Global 0.5-deg Wetland Methane Emissions and Uncertainty (WetCHARTs v1.3.3)
biosphere NASA ORNL_CLOUD Level 4 netCDF-3
In plain English

What it measures. Monthly estimates of how much methane the world's wetlands release, on a half-degree global grid, along with a sense of the uncertainty in those numbers.

How it's made. Produced not from a satellite but from an ensemble of computer models that combine biosphere models, wetland-extent scenarios, and temperature sensitivities, covering 2001 to 2022.

How & where you'd use it. Intended as an input for atmospheric chemistry and transport models; the multiple model versions let researchers explore how uncertain wetland methane emissions really are.

Official description

This dataset provides global monthly wetland methane (CH4) emissions estimates at 0.5 by 0.5-degree resolution for the period 2001-01-01 to 2022-08-31 that were derived from an ensemble of multiple terrestrial biosphere models, wetland extent scenarios, and CH4:C temperature dependencies that encompass the main sources of uncertainty in wetland CH4 emissions. There are 18 model configurations. WetCHARTs v1.3.3 is an updated product of WetCHARTs v1.3.1 dataset. The intended use of this product is as a process-informed wetland CH4 emission data set for atmospheric chemistry and transport modeling. Users can compare estimates by model configuration to explore variability and sensitivity with respect to ensemble members. The data are provided in netCDF format.
