plays an important role in atmospheric pollution
and in climate change. However, the current emission inventory of
open biomass burning is generally of highly uncertainty because of
missing small fire data and limited resolution because of the lack
of localized vegetation data. In this study, the MODIS (MODerate Resolution
Imaging Spectroradiometer) burned area product MCD64Al combined with
the active fire product MCD14 ML, as well as a high-resolution land
cover data set, were applied to develop a high-resolution emission
inventory of open biomass burning in China in 2013. Total CO, CH4, NOx, NMVOC (nonmethane volatile
organic compounds), SO2, NH3, PM2.5, PM10, OC (organic carbon), BC (black carbon), and CO2 emissions were estimated to be 1.03 × 104, 666, 536, 1.91 × 103, 87, 138, 1.45 × 103, 2.09 × 103, 741, 137, and 2.45 × 105 Gg, respectively. The provinces that contributed the most
emissions included Heilongjiang, Henan, Shandong, and Jilin. The major
source for all pollutants was cropland burning, whereas Xizang, Xinjiang,
and Heilongjiang had greater emissions from natural vegetation. The
temporal distribution of average provincial emissions showed that
the peaks were in June and October. This study updated the emission
information that may support future research and policy-making on
air pollution control and GHG emission abatement.
