We estimated the missing global carbon flux component – global belowground autotrophic respiration (RA), using global published observations with the linkage of global variables with random forest. Globally, annual mean RA was 43.8 ± 0.4 Pg C yr-1, with a temporally increasing trend of 0.025 ± 0.006 Pg C yr-2 in 1980–2012. Precipitation dominated 56 % of global areas of the spatial pattern of RA. The RA database also has great potential to serve as a benchmark for future data–model comparisons.
