The ingredients necessary to create a wildland fire are simple: a source of fuel, heat to bring the fuel to its ignition temperature, and oxygen to sustain the resulting combustion. As the fire burns, it releases smoke and other emissions. One of these emissions is carbon, the sixth most abundant element in the universe and an essential component of life on Earth. Carbon is continually cycled through processes such as burning and the decay of organic material. The integrated processes of wildland fire and carbon cycling form the cornerstones of Dr. Nancy French’s research.

Dr. French's use of remote sensing data and the application of remote sensing techniques in her research was recently highlighted by NASA's Earthdata website in their continuing series that asks the question "Who uses NASA Earth science data?"
