  • Methods for atmospheric correction of solar-wavelength hyperspectral imagery over land
    Patent number: 7337065
    Abstract: This invention discloses several improved methods of correcting for atmospheric effects on a remote image of the Earth's surface taken from above, wherein the image comprises a number of simultaneously acquired images of the same scene, each including a large number of pixels, each at a different wavelength band, and including infrared through ultraviolet wavelengths. One method is for retrieving the aerosol/haze amount (i.e., visible range) from an assumed ratio of in-band reflectances, rather than from an assumed reflectance value. Another method is for identifying cloud-containing pixels. This is used to improve the calculation of the spatially averaged radiance L*e and reflectance ?e images in standard equations. Another method greatly reduces the number of mathematical operations required to generate the reflectance values.
