Global 0.5-deg Wetland Methane Emissions and Uncertainty (WetCHARTs v1.0), 2009-2010

Bloom, A.A.; Bowman, K.; Lee, M.; Turner, A.J.; Schroeder, R; Worden, J.R.; Weidner, R.J.; McDonald, K.C.; and Jacob D.J.

This data set provides global monthly wetland methane (CH4) emissions and uncertainty data products derived from an ensemble of multiple terrestrial biosphere models, wetland extent scenarios, and CH4:C temperature dependencies. The data are at 0.5 by 0.5-degree resolution. Two model output data products are included in WetCHARTs v1.0: an output from the full ensemble for 2009-2010 and an output from a limited subset for 2001-2015. The intended use of the products is as a process-informed wetland CH4 emission and uncertainty data set for atmospheric chemistry and transport modelling (WetCHARTs).
