Atmospheric correction (AC) is an essential procedure to quantitatively analyze remote sensing data. Atmospheric effect (AE) of satellite images can be corrected to obtain surface reflectance from top-of-atmospheric signal.This study is to introduce the atmospheric correction method of SPOT satellite image.The results show that AC is important, especially at visible bands.Neglecting AC can lead relative errors of reflectance to 64% and 32% at green and red bands, respectively.The physical mechanism of AE at visible, near-IR and shortwave IR bands is also explained.
