Abstract:

Two empirical approaches to atmospheric correction of NOAA-11 NDVI data are illustrated for the arid lands of Central Australia, using (1) radiosonde data and (2) temperature differences ( T4-T5 ) between bands 4 and 5 of NOAA (split-window). Scattering angle is also shown to influence NDVI data in the Central Australian region. The split-window approach provides the better relationship and can be summarized by a linear formula. The use of preflight or sensor degradation calibrations of bands 1 and 2 have no significant influence on the strength of atmospheric correction procedures tested.
