Aerosol Optical Depth Pathways and Sources; Lake Victoria Basin*

Aerosol Optical and Micro-Physical Characteristic Derived from AERONET in Kenya*

“…The increasing size of the circle symbols indicates an increasing of AOD.number of instantaneous data of 75. A 120 hours (5 days) back trajectories at different altitudes of 1,130, 2,000 and 3,000 meters above mean sea level was used since this station is at an altitude of 1,125 m. Generally, observations showFigure 9shows most of the trajectories were originated from the southern hemisphere from south east direction.Figure 9(a), the trajectories at the altitude of 1,130 m amsl (red cycles) starts from the coastline of Mozambique in Indian Ocean and propagates along the coastline of Tanzania as it enters into Kenya, located at the border of Tanzania and the coast side of Kenya[15] [16]. This trajectory passes through industrial, agricultural and urban areas of Kenya toward western region of Kenya which might have carried large amounts of fine mode particles and industrial pollutants.…”
