  • mesoscale modeling of smoke transport from equatorial southeast asian maritime continent to the philippines first comparison of ensemble analysis with in situ observations
    Journal of Geophysical Research, 2017
    Co-Authors: Jun Wang, Jeffrey S Reid, Derek J Posselt, Peng Xian, E J Hyer
    Abstract:

    Atmospheric transport of smoke from equatorial Southeast Asian Maritime Continent (Indonesia, Singapore, and Malaysia) to the Philippines was recently verified by the first-ever measurement of aerosol composition in the region of the Sulu Sea from a research vessel named Vasco. However, numerical modeling of such transport can have large uncertainties due to the lack of observations for parameterization schemes and for describing fire emission and Meteorology in this region. These uncertainties are analyzed here, for the first time, with an ensemble of twenty-four WRF-Chem simulations. The ensemble reproduces the time series of observed surface non-sea-salt PM2.5 concentrations observed from the Vasco vessel during 17 - 30 September 2011, and overall agrees with satellite (CALIPSO and MODIS) and AERONET data. The difference of Meteorology between NCEP's FNL and ECMWF's ERA renders the biggest spread in the ensemble (up to 20 µg m-3 or 200% in surface PM2.5), with FNL showing systematically superior results. The second biggest uncertainty is from fire emissions; the 2-day maximum FLAMBE emission is superior than the instantaneous one. While Grell-Devenyi (G3) and Betts-Miller-Janjic (BMJ) cumulus schemes only produce a difference of 3 µg m-3 of surface PM2.5 over the Sulu Sea, the ensemble mean agrees best with CMORPH's spatial distribution of precipitation. Simulation with FNL-G3, 2-day maximum FLAMBE and 800-m injection height outperforms other ensemble members. Finally, the global transport model (NAAPS) outperforms all WRF-Chem simulations in describing smoke transport on 20 Sep. 2011, suggesting the challenges to model Tropical Meteorology at mesoscale and finer scale.
