Goodness of the adopted fitting relations. a the geometric mean diameter (GMD) of the emitted black carbon (BC) particles estimated by the combustor inlet temperature (T3) and the black carbon (BC) mass emission index (EIm(BC)) (defined as the mass of the emitted BC particles due to the combustion of one kilogram of fuel (g kg−1-fuel)); b the geometric standard deviation (GSD) estimated by EIm(BC). The vertical error bars represent the standard deviation of the estimations. The horizontal error bars are the uncertainties in the measurements if available
