Abstract
In this work we perform an initial assessment of the accuracy of two publicly available MODIS burned area products, MCD64A1 C6 and MODIS FireCCI51, at national scale in a Mediterranean region. The research focused on two fire seasons for the years 2016 and 2017 and comparison was performed against a higher resolution Sentinel-2 dataset. The specific objectives were to assess their capabilities in detection of fire events occurring primarily in forest and semi-natural lands and also to investigate their spatial uncertainties. The analysis combined monthly fire observations and accuracy metrics derived from error matrices. Satisfactory performance was achieved by the two products in detection of larger fires (> 100 ha) whereas their spatial performance exhibited good agreement with the reference data. MCD64A1 C6 exhibited a more consistent performance overall and the 250 m FireCCI51 product exhibited relatively higher sensitivity in detection of smaller (<100 ha) fires. Although additional work is required for a more rigorous assessment of the variability of these burned area products, our research has implications for their usability in fire-related applications at finer scales.
