REMOTE SENSING: Forest Fires
Wildfires are a
dominant influence on the biome, controlling forest successional
patterns, primary productivity, and carbon cycling. They also
inject large amounts of trace gases and smoke aerosol into the
atmosphere, both of which influence the Earth’s radiation balance.
Considering the remoteness and vast extent of the forest ecosystem,
satellite remote sensing is particularly well suited to documenting
the spatial and temporal distribution of fires so that their impact
may be quantified. Dr. Li and his former colleagues in Canada
developed an operational system composed of a suite of algorithms
that can detect fire hot spots, map fire burned scars, monitor fire
smoke, and model fire emissions. This pioneering system was
commercialized and has been employed at the Canadian Forest Services
and at NOAA.
