SPATIO-TEMPORAL FIRE PATTERNS IN THE OF THE PARANA RIVER COASTAL COMPLEX

Fire occurrences at the of Parana River Coastal Complex during the 2004-2008 period were studied through hotspot data analysis. Spatial information from different remote sensors (MODIS, ERS, Goes, NOAA) and sources (CONAE, ESA, INPE) was evaluated. The MODIS Aqua sensor (downloaded and processed by CONAE), showed a high hotspot detection performance. For this sensor, an algorithm was developed that allows the interpretation of hotspot data as fire, applying previous knowledge of the fire behavior in the study area. Maps, tables and figures were elaborated. Descriptive statistics, normality (Shapiro Willks) and variance tests (Kruskal Wallis) were carried out. No statistically significant differences (SSD) were founded between hotspots and fire occurrence to different months and seasons. SSD were found between 2004, 2006 and 2008 on the one hand, and 2005 and 2007 on the other. Taking into account these results, fires at the Parana River Coastal Complex are, in general, of short duration and small extent, with a seasonal pattern of occurrence (in spring-summer), and vary from year to year. Exceptional periods (2008) can be identified by the changes of these parameters. This information is presented as a suitable tool for the study and management of fire in the study area.
