Detection of burnt areas in Yakutia on long-term NOAA satellites data (1985-2015)

摘要

The results of processing the long-term AVHRR/NOAA data set (1985-2015) to map burnt areas using an adaptedalgorithm based on detection the changes in the NDVI vegetation index in the boreal forests of Yakutia (Eastern Siberia)are presented. Additional verification of the reliability of the identified burnt areas is made on the basis of expertevaluation. A good agreement of the detection results with MODIS data (R = 0.97) was found for the period 2001-2015.The emissions into the atmosphere of combustion products from forest fires for the period under review were estimated.
