In this study, we found the revised bottom up estimates of C fluxes and stocks from agricultural systems to be higher than those based on IPCC 2006 guidelines.
For these interventions effects of the interventions on intermediate outcomes were estimated based on systematic reviews, while intervention costs were calculated using bottom up estimates of resource use and unit costs (Table 1).
Initial estimates of complexity have been based on the number of nucleotides, genes or cell types in a genome, but such bottom up estimates often fail to have useful properties [ 4, 5].
From the imprinting model introduced above, it is expected that imprinting may have an impact on additive genetic variance of a single locus, and hence affect the bottom up estimate of heritability, as evidenced in our analysis.
That contrasts with the bottom-up estimates arrived at by tallying the earnings projections of analysts who follow individual companies.
Since the 1990s, EPA has made an annual "bottom-up" estimate for the United States.
The discrepancies between top-down and bottom-up estimates may arise from factors influencing either or both of the methods.
At the start of each year between 1982 and 1998 analysts made bottom-up estimates of all companies in the S&P 500.
The contribution of public building reconstruction is minimal, because much of the economic damage is expected to occur with private houses in the present bottom-up estimate.
Finally, we derived the long-run autonomous energy efficiency indices (AEEIs) and elasticity of substitution (ESUB) values for China, and found that the aggregate Chinese AEEIs are somewhere between top-down and bottom-up estimates in the literature.
The revised estimates allow improved reconciliation of top-down and bottom-up estimates of methane emissions, will facilitate the development and evaluation of Earth system models, and provide consistent regional and global Tier 1 estimates for environmental assessments.
