CO emissions from fossil fuels are from a merge of several inventories (for

CO emissions from '''fossil fuels''' are from a merge of several inventories. The

CO biofuel emissions are from Yevich et al.[2003, Global Biogeochemical Cycles, 17 (4), 1095, doi:10.1029/2002GB001952]. To account for production of CO from co-emitted NMHC we apply scale

emission files have been merged by Bryan Duncan using code and

inventories provided by Bob Yantosca at Harvard University:

* Global emissions:

** Fossil fuel: 371.230 Tg

** Bio-fuel: 165.776 Tg

* EDGAR (2000) is the base global emissions for CO

* '''Note''':: Base emissions are overwritten in regional areas with

+ EPA/NEI99 over continental USA (1999)

+ EMEP over Europe (??)

+ BRAVO over Northern Mexico (??)

+ David Streets over SE Asia & China (2000)

+ David Streets over China only (2001)

* no diurnal variation

* seasonal variation (+/- 10%) applied to N. America and Europe >36 N as described in Duncan et al. (2007),except for China as Streets provides monthly emissions"

'''CO biofuel''' emissions are from Yevich et al.[2003, Global Biogeochemical Cycles, 17 (4), 1095, doi:10.1029/2002GB001952]. To account for production of CO from co-emitted NMHC we apply scale

factors to the direct emission sources from fossil fuels, biofuels, and

biomass burning following Duncan et al. [2007, JGR, 112, D22301, doi:10.1029/2007JD008459]: co_ff = 1.2 * co_ff_inventory; co_bf = 1.19 * co_bf_inventory; co_bb =

'''Isoprene''' and '''terpene''' emissions were calculated by the

GMI combo model based on Guenther et al. [1995, JGR, 100 (D5), 8,873-8,892]], using GEOS-4 meteorological fields; the estimation of the production of CO from '''biogenic NMHC'' is

described in Duncan et al. [2007]. A given CO source from the oxidation of

biogenic methanol was distributed according to the emission of isoprene as

described in Duncan et al. [2007]. CO produced from methane oxidation is accounted for by using the monthly CH4 fields and assuming a CO yield of 1. The monthly CH4 fields are based on the data from the NOAA GMD sites and distributed as a function of latitude [Bian et al., 2007].~~<br>~~
