| Zusammenfassung |
| The objective of this work was to improve the fire model coupled to Hadley Centre General Circulation Model GCM - HadCM3LC. Equations which are different to those in the initial model have been proposed and tested.
During this study the simple off-line model (not coupled with GCM) has been developed (performing much faster than GCM). It has been found, that results from off-line fire model and from GCM are in good agreement, and the off-line approach could successfully be employed in the process of fire-module development and optimisation.
The process of optimisation based on maximising the correlation coefficient between computed and observed burnt fraction: GFED (Global Fire Emissions Database). The final verification of optimal parameters found in off-line model has been done by their implementation to GCM. In effect of presented researches the correlation coefficient between improved fire model and observed burnt fraction has been increased from R=0.1549 (initial model) to R=0.4032 (modified one). Computed burnt area has been validated against other product of burnt area (L3JRC). |
