  abstract = {{W}e examined the relationships between fires detected by the {A}long {T}rack {S}canning {R}adiometer, algorithm 2 ({ATSR}-2) and the {M}oderate {R}esolution {I}maging {S}pectrometer ({MODIS}) sensors and local-scale atmospheric conditions in {N}ew {C}aledonia ({SW} {P}acific similar to 165.5 degrees {E}, 21.5 degrees {S}) during the 1996-2008 ({ATSR}) and 2000-2008 ({MODIS}) time periods. {A} total of 3707 ({MODIS}) hotspots, representing 949 distinct fires, and 83 ({ATSR}) hotspots were observed during the study period. {T}he annual mean frequency of hotspots peaks around the transition between the dry-cool season and the wet-warm season, that is, in {S}eptember-{D}ecember, when dry soils and fuels could be combined with increasing temperatures. {T}he antecedent local-scale maximum temperature and rainfall anomalies recorded at the closest meteorological station were analyzed. {W}hile the signal in maximum temperature is weak and not robust among the fire records, the local-scale anomalies of rainfall are always clearly negative for at least 3 months before the fires (i.e., between {J}une and {D}ecember). {T}he {E}ffective {D}rought {I}ndex ({EDI}), based on rainfall only, and the {F}ire {W}eather {I}ndex ({FWI}), which combines rainfall, temperature, relative humidity, and wind speed, show similar behaviors before fires. {T}his suggests that a simple rainfall index, as well as a more comprehensive one, is able to diagnose fire risks. {A}t interannual time scale, cross-correlation analysis reveals that the seasonal {J}une-{A}ugust {N}ino 3.4 sea surface temperature index is strongly correlated (r = 0.78 for a second-order polynomial fit) with the monthly frequency of all {MODIS} hotspots in {S}eptember-{D}ecember, suggesting a strong potential predictability of fire variations in {N}ew {C}aledonia with a lead time of 1-4 months.},
