Abstract Satellite data are effective for mapping wildfires, particularly in remote locations where monitoring is rare. Geolocated fire detections can be used for enhanced fire management and fire modelling through daily fire progression mapping. Here we present the Canadian Fire Spread Dataset (CFSDS), encompassing interpolated progressions for fires >1,000 ha in Canada from 2002–2021, representing the day-of-burning and 50 environmental covariates for every pixel.

1 INTRODUCTION The circumpolar boreal biome contains approximately one-third of the world's forests, making it a globally important carbon store (Bradshaw & Warkentin, 2015; Gauthier et al., 2015). Wildfires are the major stand-renewing disturbance across much of the boreal forest (Guindon et al., 2014; Jones et al., 2022), and account for approximately 1.9 Mha of area burned each year in Canada (Hanes et al., 2019).
