Figure 3 (a-e) The correlation coefficient (CCF) of Niño 3 anomaly-fire count at various lag times (ie. 
negative lag number). Positive lag numbers (lead time) were ignored since current and past fire events 
cannot be explained and attributed to future ENSO variations. The higher the coefficient the stronger the 
ENSO-fire correlation; horizontal black line depicts the 0.5 confidence limits; (a) 1982-83, (b) 1986-87, (c) 
1991-92, (d) 1993-94, and (e) 1997-98. (f) The 16-month sum of Niño 3 anomaly, from January of Year 0 to 
April of Year 1, versus the 16-month cumulative all-Borneo fire counts over the same time period for the
