"Detection of Biomass Burning Smoke from TOMS Measurements,"
N.C. Hsu (Hughes STX, 7701 Greenbelt Rd. (#400), Greenbelt MD 20770), J.R.
Herman et al., Geophys. Res. Lett., 23(7), 745-748, Apr. 1,
Demonstrates the ability of the TOMS instrument to detect and track smoke
and soot aerosols generated by biomass burning in South America, using a
14.5-year gridded data set of tropospheric absorbing aerosol index derived from
the Nimbus-7 Total Ozone Mapping Spectrometer. TOMS data can distinguish between
absorbing particles (smoke and dust) and non-absorbing particles (clouds and
"Fluxes of Nitric Oxide from Soils Following the Clearing and
Burning of a Secondary Tropical Rain Forest," J.C. Neff (Atmos. Chem. Div.,
NCAR, POB 3000, Boulder CO 80307), M. Keller et al., J. Geophys. Res.,
100(D12), 25,913-25,922, Dec. 20, 1995.
At sites in the Atlantic Lowlands of Costa Rica, clearing and burning of a
secondary tropical rainforest caused a significant increase in soil NO release,
which peaked for 1-3 days following burning, and remained elevated for 3-4
months. A number of experiments on soil cores reveal some of the relevant
"Spatial and Temporal Distribution of Tropical Biomass Burning,"
W.M. Hao (Intermountain Fire Sci. Lab., USDA Forest Serv., POB 8089, Missoula MT
59807), M.-H. Liu, Global Biogeochem. Cycles, 8(4), 495-503,
Presents a database for the temporal and spatial distribution of the amount
of biomass burned in tropical America, Africa, and Asia during the late 1970s,
at a 5° latitude-longitude resolution. The contributions to total biomass
burned are: savanna fires (50%), shifting cultivation (24%), deforestation
(10%), fuel wood use (11%), and burning of agricultural residues (5%). Land use
changes during the last decade could have a profound impact on the amount of
biomass burned and the amount of trace gases and aerosol particles emitted.
