The files include the data used by Girardin and Mudelsee (2007) for calibrating the FireOcc model (LFDB_FireOcc.txt) and predicting past (DroughtReconstructions.txt) and future (ECHAM4-CGCM3_simulations.txt) changes in FireOcc. The generated FireOcc estimates are found in the file FireOcc_estimates.txt. Estimates of occurrence rates of extreme fire years are presented in the file XTREND_output.txt.

RAMPFIT is a software program for estimating change-points in a time series. RAMPFIT has been used by Girardin and Mudelsee (2007) to detect changes in the FireOcc time series. The provided executable (rampfit.exe) runs under Windows operating systems. In addition to RAMPFIT, the freeware Gnuplot viewer has to be installed to visualize results. Further information:

(1) readme.txt file included in the software file contains hints for installation;

(2) Mudelsee (2000) paper contains the mathematics and also a short manual;

(3) rampfit.for source code included in the software file has details on numerical implementation.
