Distribution of dicarboxylic acids and carbon isotopic compositions in aerosols from 1997 Indonesian forest fires
Open accessAbstract
Fine aerosol particles collected in Southeast Asia during 1997 Indonesian forest fires were studied for the concentrations of total carbon (TC), water‐soluble organic carbon (WSOC) and low molecular weight dicarboxylic acids (C 2‐C 12) as well as carbon isotopic ratios of TC (δ 13 C TC). TC and WSOC showed a large increase during the heavy forest fire event. At the same period, dicarboxylic acids, dominated by oxalic (C 2) followed by succinic (C 4) and malonic (C 3) acids, also showed a concentration increase. Furthermore, the δ 13 C TC showed a decrease from ca. −25.5 to −27.5‰ during an intensified forest fire event, suggesting an addition of organic aerosols derived from C3 plants whose δ 13 C are lighter. These results indicate that the aerosol particles in Southeast Asia were significantly affected by the combustion processes of vegetations during the 1997 Indonesian forest fires that were extensively induced by El Ninõ event.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
