ABSTRACT: The three measurement periods: the TOMS Nimbus-7
TOMSN7L3 v008 from 1978 to 1993, the TOMS EP TOMSEPL3 v008 from 1996 to 2005
and the OMI OMTO3d v003 from 2004 to 2008 have allowed the presence of dust to
be observed in the 10° North to 20° North latitudinal band (10 - 20 band) of Africa. The 10 - 20 band has a permanent dust presence. The AERONET
data show AOD peaks exceeding 2 in Senegal and Niger (on an AOD scale). The statistical study reveals intra-annual
relationships in deposition. In Senegal, a significant deposition is
observed.
