text: Expressed as a percentage, the atmospheric dust spot efficiency can then be calculated from the following relationship: E = 100 × (1–Q1O2/Q2O1) where E = the atmospheric dust spot efficiency, %; Q1 = the total volume of air drawn through the upstream target; Q 2 = the total volume of air drawn through the downstream target; O 1 = the opacity of the dust spot on the upstream target = (T u1 – T u2 )/T
