Abstract

The problem of characteristic vertical profile of smoke released from
wildland fires is considered. A methodology for bottom-up evaluation of
this profile is suggested and a corresponding global dataset is
calculated. The profile estimation is based on: (i) a semi-empirical
formula for plume-top height recently suggested by the authors, (ii)
satellite observations of active wildland fires, and (iii)
meteorological conditions evaluated for each fire using output of the
numerical weather prediction model. Injection profiles of the plumes
from all fires recorded globally from March 2000 till November 2012 are
estimated with a time step of 1 h. The resulting 4-dimensional dataset
is split into daytime and nighttime subsets. The subsets are projected
onto a global grid with a resolution of 1 degrees x 1 degrees x 500 m,
aggregated to a monthly level, and normalised by total emissions in each
vertical column. Evaluation of the obtained dataset was performed in
several ways. Firstly, the quality of the semiempirical formula for
plume-top computations was evaluated using updated MISR fire Plume
Height Project data. Secondly, the upper percentiles of the profiles are
compared with an independent dataset of space lidar CALIOP. Thirdly, the
results are compared with the distribution suggested for AEROCOM
modelling community. Finally, the inter-annual variations of the
calculated profiles are estimated.
