Atmospheric aerosol samples were collected in the Ivory Coast, primarily at
Lamto (6°N, 5°W) between 1979 and 1981. The samples were analysed for total
particulate carbon concentration and isotopic composition (13C/12C) by mass
spectrometry. Observed concentrations were found high compared to values
reported for temperate regions. Fine particulate carbon in the submicrometersize
range accounted fo... hiện toàn bộ
A photochemical scheme including a detailed description of multiple seattering
up to solar zenith angles of 960 has been used to study a number of different
datasets. The good agreement of the model with these datasets and the
improvement over previous intercomparisons emphasise the importance of both the
diffuse radiation field at wavelengths below 310 nm and multiple scattering at
solar zenith a... hiện toàn bộ
