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
