Characterizing the spectral-temporal response of burned savannah using in situ spectroradiometry and infrared thermometry

The spectral evolution of a savannah site in north-east Namibia was recorde d in situ for 13 days after it burned, using a portable spectroradiometer ( 704 bands in the range 0.35 to 2.5 mu m) and an infrared thermometer (one b and, 6 to 14 mu m). Analysis of the data reveals strengths and limitations of single spectral bands for the detection of burned savannah at different days after the fire, with important implications for the potential use of s atellite sensors, in particular MODIS.
