Classification of Aerosol Types over Ghardaia, Algeria, Based on MODIS Data
Zaiani Mohamed, Djafer Djelloul, and Chouireb Fatima
Abstract—Anthropogenic and natural aerosols are important
atmospheric constituents that significantly contribute to the
Earth’s radiation budget but remain uncertainties due to the
poor understanding of their properties and their direct effects
on scattering and absorption of solar radiation and their ability
to stay in atmosphere for a very short time. The aerosol
properties retrieved from the Moderate Resolution Imaging
Spectroradiometer (MODIS) measurements collected during
the period 2004-2012 are used for the first time to identify the
types of aerosols over Ghardaia city. Two parameters are used
for aerosol analyses, the Aerosol Optical Thickness (AOT) and
the Angstrom exponent (α). The obtained results show different
types of aerosols, representing biomass-burning, urban,
maritime and dust aerosols. The aerosol type discrimination
shows a clear domination of urban aerosols compared to
maritime, dust and biomass-burning aerosols. They represent
respectively the fractions of 54 %, 32%, 13 % and 1%.
Index Terms—Aerosol optical thickness, aerosols, dust aerosols, urban aerosols, maritime aerosols, biomass-burning aerosols, angstrom exponent, angstrom coefficient.
