Abstract: Relationships between the daily values of total precipitable water in the atmosphere and the surface humidity parameters are presented from sunphotometric investigations made daily during the year 1981 and 1982. Turbidity ...

Abstract: This paper presents results of 14 months of ground-based measurements of spectral aerosol optical thickness and horizontal extinction together with related studies such as relations between these parameters, meteorological ...

Abstract: We present a collection of experimental data concerning turbulent characteristics of the convective boundary layer. These data were obtained by means of instrumented aircraft during numerous experiments carried out above ...

Abstract: Spectral aerosol optical depths were measured in seven localities of Niger (West African Sahel) from February 1986 to June 1987. Results of these observations, together with related climatic parameters, are presented and ...
