Fire Ecology

Table 2 Coefficients and goodness of fit of the best fit equations for the prediction of monthly Fire Density Index from Dead Ratio values for each vegetation type and region in Mexico, for the period 2003 to 2014. Veg_region: vegetation and region; Eq: best fit equation from Table 1; a, b, and rho are global parameters; a1 to a12 are parameters associated to the corresponding months (January to December) or group of months; RMSE: Root Mean Square Error; R²adj: adjusted R²; AIC: Akaike’s Information Criterion; AG: Agriculture; ARBSV: Arborous Secondary Vegetation; DTROPF: Deciduous Tropical Forest, PAS: Pastureland, PTROPF: Perennial Tropical Forest, SHSV: Shrubby Secondary Vegetation; TFOR: Temperate Forest; and NW: Northwest region, NE: Northeast region, C: Central region, S: South region

From: Temporal patterns of active fire density and its relationship with a satellite fuel greenness index by vegetation type and region in Mexico during 2003–2014
