[2003] PALM = Palmer et al. [2003] CARM = Carmichael et al. [2003] INVERSE = Inverse results using NOAA CMDL CO FOOTNOTE: a = FFBF from EDGAR/RIVM, BB from Van der Werf et al. [2003] b = Taken as minimum and maximum estimates for 4 cases of error covariance for each subset of MOPITT data. The two-sigma uncertainty is taken as twice the root mean square of the 4 error cases. c = Includes China, Korea and Japan d = Total southeast Asian CO emission (FFBF + BB) e = From Kasibhatla et al. [2002] and Pétron et al. [2002], respectively; (estimates representative of 1990s) f = Includes south and southeast Asia and China g = Doubled Streets et al. [2003] FFBF domestic emissions h = Suggested an underestimation of Streets et al. [2003] 66 Tg CO/yr BB emissions in Asia
