Compilation of global soil GHG estimates

I collected reported global estimates of soil CO2 emission, CH4 uptake, and N2O emission (natural soil). Data of Figure 5 in Hashimoto (2012). Please see the paper (open access) for details, especially the caption of Figure 5.

Japanese forests' gridded soil CO2 emission, CH4 uptake flux, and N2O emission (and snow, soil temperature, and soil water (water filled pore space))

Soil greenhouse gas fluxes were estimated using a simple semi-empirical model for Japanese forests. Also, snow, soil temperature (5cm), and soil water (water filled pore space (5cm)) were estimated. Described in the publication, Hashimoto, S., T. Morishita, T. Sakata and S. Ishizuka (2011) Increasing trends of soil greenhouse gas fluxes in Japanese forests from 1980 to 2009.
