Wildfires are the most prevalent natural disturbance in Canadian boreal forests, which could cause postfire land surface temperature change (ΔLST) through biophysical processes. Here, we used multiple remote sensing products and spatial GIS analysis methods to investigate the fire-induced daytime and nighttime LST change over Canada’s boreal forest from 2004 to 2017. We further examined the differences of ΔLST among three forest types. We found a pronounced asymmetry in diurnal ΔLST, characterized by daytime warming in contrast to nighttime cooling. The differences in the effects of forest fires on diurnal surface temperature were also exhibited among three forest types. The effect of wildfires on diurnal surface temperature is more significant in evergreen forest areas than in deciduous forest areas. These results also revealed that species composition has a strong influence on the climate effects of fire in boreal regions.
