Published July 1988 through June 1999
FROM VOLUME 8, NUMBER 1, JANUARY 1995
in J. Geophys. Res., 99(D11), Nov. 20, 1994:
"A Two-Dimensional Global Study of Tropospheric Ozone
Production," A. Strand (Nansen Environ. Sensing Ctr., N-5037
Bergen-Solheimsviken, Norway), O. Hov, 22,877-22,895. A
transport-chemistry model shows that a 50% cut in industrial VOC
emissions leads to about half the reduction in summertime O3
production as does a 50% cut in NOx emissions.
"Interannual Variability over the Eastern North Atlantic
Ocean: Chemical and Meteorological Evidence for Tropical
Influence on Regional-Scale Transport in the Extratropics,"
B.G. Doddridge (Dept. Meteor., Univ. Maryland, College Pk. MD
20742), P.A. Dirmeyer et al., 22,923-22,935. Estimates O3
production over western Europe using CO as a tracer for
short-lived anthropogenic precursors.
"Convective Transport over the Central United States and Its
Role in Regional CO and Ozone Budgets," A.M. Thompson
(NASA-Goddard, Greenbelt MD 20771), K.E. Pickering et al., J.
Geophys. Res., 99(D9), 18,703-18,711, Sep. 20, 1994.
The central U.S. acts as a chimney for the country. Boundary
layer venting of CO and other O3 precursors leads to efficient
free tropospheric O3 production, which contributes to high
background levels in the eastern U.S. and ozone export to the
"Evidence of a Long-Term Increase in Tropospheric Ozone from
Pic du Midi Data Series: Consequences: Positive Radiative
Forcing," A. Marenco, H. Gouget et al., J. Geophys. Res., 99(D8),
16,617-16,632, Aug. 20, 1994 (See Global Climate Change Digest,
"Experiment Probes Elevated Ozone Levels over the Tropical
South Atlantic Ocean," J. Fishman (MS 401A, NASA-Langley,
Hampton VA 23681), Eos, 380, Aug. 16, 1994.
TRACE-A (airborne) measurements give insight into the elevated
ozone levels found during September and October 1992. This ozone
anomaly is due to complex interaction of chemical and
meteorological processes. Complete interpretation of the results
is underway and incorporates the use of satellite imagery and a
meteorological model of the tropics.
"Relationship of Ozone and Carbon Monoxide over North
America," M. Chin (Dept. Earth & Planetary Sci., Harvard
Univ., Cambridge MA 02138), D.J. Jacob et al., J. Geophys.
Res., 99(D7), 14,565-14,573, July 20, 1994.
Field data that show a strong correlation between O3 and CO
concentrations in summer offer a test for evaluating the ability
of photochemical models to simulate O3 production. A
three-dimensional, continental-scale model gave a good
simulation. Explores the use of the DO3/DCO ratio as indication
of anthropogenic sources.
"Effects of Reductions in Stratospheric Ozone on
Tropospheric Chemistry Through Changes in Photolysis Rates,"
J.S. Fuglestvedt, J.E. Jonson, I.S.A. Isaksen, Tellus, 46B(3),
172-192, July 1994. (See Global Climate Change Digest, p.
"Climatology of Tropospheric Ozone in Southern Europe and
Its Relation to Potential Vorticity," M. Beekmann (CNRS,
Univ. Paris, Boite 102-4, Pl. Jussieu, 75252 Paris cedex 05,
France), G. Ancellet, G. Mégie, J. Geophys. Res., 99(D6),
12,841-12,853, June 20, 1994.
Statistical analysis of data from balloon-borne sondes shows
that the interannual variability of potential vorticity can cause
dynamically induced trends of ozone concentration, which must be
taken into account to accurately determine the portion from human
"Role of Deep Cloud Convection in the Ozone Budget of the
Troposphere," J. Lelieveld (Air Quality Dept., Wageningen
Univ., POB 8129, 6700 EV Wageningen, Neth.), P.J. Crutzen, Science, 264(5166),
1759-1761, June 17, 1994.
Model simulations suggest that the net result of upward and
downward transport processes is a 20% overall reduction in total
tropospheric O3. However, the net atmospheric oxidation
efficiency is enhanced by 10% to 20%
"Growth of Continental-Scale Metro-Agro-Plexes, Regional
Ozone Pollution, and World Food Production," W.L. Chameides,
P.S. Kasibhatla et al., Science, 264(5155), 74-77,
Apr. 1, 1994. (See Global Climate Change Digest, May 1994)
"Year 2020: Consequences of Population Growth and
Development on Deposition of Oxidized Nitrogen," J.N.
Galloway, H. Levy II, P.S. Kasibhatla, Ambio, 23(2),
120-123, Mar. 1994. (See Global Climate Change Digest, May
issue: "Surface Ozone," Atmos. Environ., 28(1),
Jan. 1994. Contains 15 papers that present data from a global
network and from several countries, and discuss trends,
meteorological parameters, anthropogenic influences, and the
stratospheric intrusion phenomenon and its impact on
