Wildfire smoke influences on air quality and atmospheric chemistry have been underscored by the increasing fire prevalence in recent years, and yet, the connection between fire, smoke emissions, and the subsequent transformation of this smoke in the atmosphere remains poorly constrained. Toward improving these linkages, we present a new method for coupling high‐time‐resolution satellite observations of fire radiative power (FRP) with in situ observations of smoke aerosols and trace gases. We apply this technique to thirteen fire plumes comprehensively characterized during the recent FIREX‐AQ mission and show that changes in FRP directly translate into changes in conserved smoke tracers (CO₂, CO, and black carbon aerosol) observed in the downwind smoke plume. The correlation is particularly strong for CO₂ (mean r>0.9). This method is important for untangling the competing effects of changing fire behavior versus the influence of dilution and atmospheric processing on the down‐wind evolution of measured smoke properties.
