The importance of measuring and monitoring fire related ecosystem characteristics in forests is recognized and is the focus of several new studies. In this paper we present a discussion on the use of remote sensing for the study of boreal forest fire scar characteristics. Remote measurements of geophysical parameters and model inputs are discussed. It is recognized that remote measurements need to be combined with field measurements and modeling. Specific examples on recent work using infrared remote sensing for fire scar studies are presented and discussed in detail. Results of this work have shown that shortwave infrared systems can be used to map fire severity. Thermal infrared systems can be used to monitor surface temperature changes, to map thermal characteristics of the burn scar surface, and can potentially be used in the modeling of surface energy fluxes. Generally, remote sensing can provide unique information at a variety of scales for the study of fire ecology.
