BIOMASS BURNING
Item #d93dec44
 Two items from J. Geophys. Res., 98(D9), Sep. 20, 1993:
"Rainforest Burning and the Global Carbon Budget: Biomass, Combustion
Efficiency, and Charcoal Formation in the Brazilian Amazon," 16,733-16,743.
(See Global Climate Change Digest, Oct. 1993)
"A Seasonal Cycle in the Southwest Pacific Free Tropospheric Aerosol
Concentration," I.S. Kristament (Nat. Inst. Water/Atmos. Res., POB 31-311,
Lower Hutt, N.Z.), M.J. Harvey, J.B. Liley, 16,829-16,837. The pronounced spring
maximum observed at 30·S is likely a result of biomass burning in the
tropical Southern Hemisphere dry season.
Item #d93dec45
"Airborne Measurements of Gases and Particles from an Alaskan
Wildfire," J.D. Nance (Dept. Atmos. Sci., AK-40, Univ. Washington, Seattle
WA 98195), P.V. Hobbs, L.F. Radke, ibid., 98(D8), 14,873-14,882,
Aug. 20, 1993.
Results are generally consistent with other studies, with the possible
exception of relatively high CH4 emissions and large particle diameters.
Item #d93dec46
"Trace Gas Emissions from Tropical Biomass Fires: Yucatan Peninsula,
Mexico," W.R. Cofer (Atmos. Sci., NASA-Langley, Hampton VA 23681), J.S.
Levine et al., Atmos. Environ., 27A(12), 1903-1907, Aug. 1993.
Measured mixing ratios of CO2, CO, H2, CH4 and total non-methane
hydrocarbons (TNMHC) from two prescribed fires in forests similar in composition
to Brazilian rainforest. Found high TNMHC emission ratios.
Item #d93dec47
"Savanna Fires and Seasonal Temperatures: A Case for Research?"
C.G. Trapnell (2 Ivywell Rd., Bristol BS9 1NX, UK), Environ. Conserv.,
20(2), 168-170, Summer 1993.
A long-term resident of tropical Africa and agricultural specialist calls
for research on the link between biomass burning and seasonal temperatures, in
the framework of climate change.
Item #d93dec48
Comment on diurnal cycles in savanna fires, Nature, 363(6425),
120, May 13, 1993.
Item #d93dec49
"Global Distribution of Fires from Space," M.O. Andreae
(Biochem. Dept., M. Planck Inst. Chem., POB 3060, D-6500 Mainz, Ger.), Eos,
74(12), 129, 135, Mar. 23, 1993.
Analysis of the recently released collection of hand-held photographs from
the NASA Space Shuttle Earth Observations Project provides the first global and
long-term view of large biomass fires.
Item #d93dec50
"Some Trace Gas Emissions from North American Biomass Fires with an
Assessment of Regional and Global Fluxes from Biomass Burning," K.K.
Laursen (NCAR, POB 3000, Boulder CO 80307), P.V. Hobbs et al., J. Geophys.
Res., 97(D18), 20,687-20,701, Dec. 20, 1992.
Draws general conclusions from airborne measurements of 13 biomass fires in
North America. Extrapolation of results leads to an estimate of world emissions
of CH4, NMHC, H2 and NH3 of 8%, 17%, 24% and 7%, respectively.
