Biomass burning releases significant amounts of trace gases and smoke aerosol into the atmosphere. This has an impact on the Earth's radiation budget, the magnitude of which has not yet been well quantified. Satellite remote sensing is well suited to assessing the area of…

Traditional biogeochernical theories suggest that ecosystem nitrogen retention is controlled by biotic N limitation, that stream N losses should increase with successional age, and that increasing N deposition will accelerate this process. These theories ignore the role of…
