Cover Story: The ability to map burn severity and to understand how it varies as a function of the time of year and return frequency is an important tool for landscape management and carbon accounting in tropical savannas. Different indices based on optical satellite images are typically used for mapping fire scars and for estimating burn severity. However, cloud cover is a major limitation for analyses using optical data. In this article, we demonstrated the potential of C-band synthetic aperture RADAR (SAR) data for burn severity mapping in tropical savanna landscapes. In conjunction with optical satellite data, we used terrestrial laser scanning (TLS) measurements to validate our findings, making this study unique. We found that the SAR data contributed valuable information which was correlated with optical observations and the TLS measurements following fires.View this paper.
