# Canada 2023 Wildfires | ||
|
||
Canada's 2023 wildfire season represented the largest area burned in a single fire season in Canada’s modern history. Using the Tracking Intra- and | ||
Inter-year Change (TIIC) algorithm, wildfires occurring within Canada’s forested ecosystems during the 2023 fire season were detected at a 30-m | ||
resolution. Time series data used to identify wildfires originated from Sentinel-2A and -2B, and Landsat-8 and -9. Fires have been grouped into two | ||
classes based on detection period: summer fires and fall fires. Summer fires were detected between May 30 and September 17, and fall fires were | ||
detected between September 17 and October 25. For summer fires, burned pixels were identified by TIIC as changed and typed as fire. | ||
|
||
For the fall period, TIIC only detected changes within a 4-km buffer of NRCan fire perimeters (https://cwfis.cfs.nrcan.gc.ca/datamart). This | ||
approach was used to limit commission errors that can occur due to known limitations of mapping with optical data in the fall due to phenology, snow | ||
cover, or low sun angles. For the 2023 fire season, the TIIC algorithm detected 12.74 Mha of burned area in Canada’s forested ecozones, representing | ||
1.8% of the total forest-dominated ecozone area. Of the 12.74 Mha, 11.57 Mha (90.9%) was burned by summer fires and 1.16 Mha (9.1%) by fall fires | ||
