Arctic Boreal Annual Burned Area, Circumpolar Boreal Forest and Tundra, V2, 2002-2022

This dataset provides annual cumulative end-of-season burned area in circumpolar boreal forests and tundra for the years 2002-2022. The data were generated using the Arctic Boreal Burned Area (ABBA) version 2 algorithm with MODIS collection 6 products. The algorithm is based on Normalized Burned Ratio differencing (dNBR) and is designed specifically to capture late season fires. The annual MODIS Vegetation Continuous Fields (VCF) 250-m Collection 5.1 (MOD44B) product allowed for additional vegetation-dependent dNBR thresholds within the algorithm's processing steps. The spatial domain is circumpolar regions above 50 degrees north latitude. The data are provided in cloud-optimized GeoTIFF format with 463-m resolution.

本数据集提供了2002年至2022年环北极地区针叶林和苔原地区的年度累积季节末烧毁面积。数据采用北极森林烧毁面积（ABBA）版本2算法生成，该算法基于MODIS系列6产品。该算法基于归一化烧毁比差异（dNBR）原理，旨在专门捕捉季节末火灾。年度MODIS植被连续场（VCF）250米分辨率系列5.1（MOD44B）产品使得在算法处理步骤中能够设置额外的植被依赖性dNBR阈值。空间域为北纬50度以上的环北极地区。数据以云优化GeoTIFF格式提供，分辨率为463米。
