    • Characterization and transport of aerosols over equatorial eastern Africa 

      Gatebe, C. K; Tyson, P. D; Annegarn, H. J; Helas, G; Kinyua, A. M; Piketh, S. J. (University of Nairobi, 2001-09)
      Measurements of the composition of aerosol partitioned into two size fractions, fine (particle aerodynamic equivalent diameter, dp <= 2.5 mum) and coarse (2.5 < dp <= 10 mum) were made at a high-altitude site over equatorial ...

    • A seasonal air transport climatology for Kenya 

      Gatebe, C K; Tyson, P D; Annegarn, H; Piketh, S; Helas, G (University of Nairobi, 1999-06)
      A climatology of air transport to and from Kenya has been developed using kinematic trajectory modeling. Significant months for trajectory analysis have been determined from a classification of synoptic circulation fields. ...
