This page offers access to a number of datasets which describe the exchange of methane between Earth's surface and atmosphere. They have been used in simulations of atmospheric CH4 using the GISS three-dimensional tracer transport model. An overview of the datasets and the model runs is given in Fung et al. (1991) (see References below).
Listed source strengths are global sums from the datasets. In many cases, they are arbitrary values assumed for mathematical convenience. See Fung et al. (1991) for a discussion of the actual source strengths and their uncertainties.
Individual files according to methane source may be downloaded via the following links; All are gzipped ASCII-text tables and none exceed 15-kb in length. All are at 1L×1° resolution.
