High-altitude tracking by chemical smokes
Dilute smokes, those that scatter light radially, can provide proper contrast only at predawn; for daylight tracking proper contrast can be provided only by dense smoke that backscatters 90% or more of incident light; it is estimated that 100 lb of chemicals and equipment are required to produce 2 ft smoke track between 60,000 and 200,000 ft in daylight.
