abstract = "Sixteen years of analysis of clear-sky direct aerosol radiative
forcing is presented for the Amazon region, with calculations of
AERONET network, MODIS sensor and MERRA-2 reanalysis data. The
results showed that MERRA-2 reanalysis is an excellent tool for
calculating and providing the spatial distribution of aerosol
direct radiative forcing. In addition, the difference between
considering the reference state of the atmosphere without aerosol
loading and with natural aerosol to obtain the aerosol direct
radiative forcing is discussed. During the dry season, the monthly
average direct forcing at the top of atmosphere varied from -9.60
to -4.20W m\−2, and at the surface, it varied from -29.81
to -9.24W m\−26 , according to MERRA-2 reanalysis data and
the reference state of atmosphere without aerosol loading. Already
with the state of reference being the natural aerosols, the
average direct forcing at the top of atmosphere varied from -5.15
to -1.18W m\−2, and at the surface, it varied from -21.28
to -5.25W m\−2; this difference was associated with the
absorption of aerosols.",
