The emission rate of light‐absorbing aerosols, which contribute to climate forcing, has previously been calculated using mass emission factors combined with fuel‐use inventories. Several assumptions made in this calculation lead to overestimates that are significant, but as yet unevaluated. We propose a new measurement approach that augments, and may be preferable to, the mass‐based method for modeling radiative forcing by aerosols: direct measurement of the source strength of absorption. This quantity, in units of absorption cross‐section per unit time, may be used directly in models of atmospheric dispersion and transport to predict the three‐dimensional, time‐dependent distribution of the absorption of visible light by aerosols. In demonstration measurements made at a coal‐burning plant, the emitted absorption is an order of magnitude lower than would be inferred from the previous method of calculation.
