Saharan Air Layer

Saharan Air Layer (SAL)

While some of the goals of this mission type may be accomplished as part of the Evolution of Easterly Wave missions, especially those close to Cape Verde, it is necessary to have some dedicated missions or modules where penetration and direct aerosol sampling of the dust layer is accomplished. One may envision some runs above the SAL, preferentially crossing its southwestern boundary to determine structure and gradients, followed by direct sampling within the dust layer and perhaps into the BL as well. (Dust layer is expected to be between 1.5 and 4.5 km, more or less.)
