MAPPING FOREST DISTURBANCES IN NORTHERN EURASIA

MODTrendr algorithm (Sulla-Menashe et al., 2014) was applied to 14-year time series of peak-summer Normalized Burn Ratio (NBR) composites derived from the MODIS Nadir BRDF-Adjusted Reflectance product (Schaaf et al., 2002). MODTrendr predicts timing (first year), duration (number of years) and magnitude (differenced Normalized Burn Ratio, dNBR) of the greatest forest disturbances. Only short-term disturbances of duration less than 6 years were considered.
