Daily energy release component (ERC) values from the Jemez RAWS station for the period 1966 to 2009, derived using FireFamily Plus. Fire season, defined when ERC exceeds the 90th percentile value, begins on average on 1 April and ends on 1 August, but we extended the fire season to 1 September to account for the lag in 100-hour and 1000-hour fuels. Historical records show a bimodal fire season in extreme years. Time series values are for average (green line) and maximum (red line) observed ERC values. The 90th percentile value is indicated by the gray line and the 97th percentile value is indicated by the black line.
