Regional Spatiotemporal Patterns of Fire in the Eurasian Subarctic Based on Satellite Imagery

The fire risks in the vast Eurasian Subarctic are increasing, raising concerns for both local and global climate systems. Although some studies have addressed this problem, their conclusions only draw from relatively lower resolution data, and the sub-regional analysis of fire patterns in this area...
