  abstract = {{A}pproximately three years of sunphotometric measurements carried out in the locality of {B}idi (13.36 degrees {N}; 2.30 degrees {W}) in {B}urkina {F}aso ({W}est {A}frica) from {O}ctober 1986 to {J}anuary 1989 were used to estimate the atmospheric precipitable water vapour ({APW}) and the {A}ngstrom exponent values a. {A} study of the relationship between these two parameters on a seasonal time scale shows that an increase of water vapour in the {S}ahel is associated with a decrease of a values, indicating hygroscopic growth of aerosol particles. {T}his result shows that the {S}ahel aerosol particles may grow in size through water vapour absorption due to hygroscopic properties.},
