FROM VOLUME 8, NUMBER 4, APRIL 1995
BIOGEOCHEMICAL CYCLES: CARBON MONOXIDE
Radical-Initiated Photooxidation of Isoprene: An Estimate of
Global CO Production," A. Miyoshi (Dept. Reaction Chem.,
Univ. Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo 113, Japan), S.
Hatakeyama, N. Washida, J. Geophys. Res., 99(D9),
18,779-18,787, Sep. 20, 1994. Estimates global CO production from
natural hydrocarbons to be 200 ± 60 Tg C/yr.
"Ozone and Carbon Monoxide Measurements at a Remote Maritime
Location, Mace Head, Ireland, from 1990 to 1992," R.G.
Derwent (U.K. Meteor. Off., Bracknell, Berkshire RG12 2S7, UK),
P.G. Simmonds, W.J. Collins, Atmos. Environ., 28(16),
2623-2637, Sep. 1994. CO concentrations for northwest Europe
increased over the period by about 0.8 ppb/yr.
"Global Decrease in Atmospheric Carbon Monoxide
Concentration," (see Global Climate Change Digest,
"Carbon Monoxide Budget in the Northern Hemisphere,"
P.S. Bakwin (CIRES, Univ. Colorado, Boulder CO 80309), P.P. Tans,
P.C. Novelli, Geophys. Res. Lett., 21(6), 433-436,
Mar. 15, 1994.
Used a simple two-box model to examine the impact of shrinking
emissions and increasing OH on global abundance, and found each
contributes about equally in reducing CO levels in the
troposphere by about 1.8 ± 0.8 ppb/yr on average.
"Routine, Continuous Measurement of Carbon Monoxide with
Parts per Billion Precision," D.D. Parrish (Aeron. Lab.,
NOAA, Boulder CO 80303), J.S. Holloway, F.C. Fehsenfeld, Environ.
Sci. Technol., 28(9), 1615-1618, Sep. 1994.
"Reevaluation of the NOAA/CMDL Carbon Monoxide Reference
Scale and Comparisons with CO Reference Gases at NASA-Langley and
the Fraunhofer Institut," P.C. Novelli (CIRES, Univ.
Colorado, Boulder CO 80309), J.E. Collins Jr. et al., J.
Geophys. Res., 99(D6), 12,833-12,839, June 20, 1994.
