At the same time, the probe's Descent Imager and SpectralRadiometer (DISR) will take pictures of the methane clouds so that researchers can determine their size and shape.
The principle, apparatus, calibration methods of the spectralradiometer calibration for airborne multispectral scanners are described. The experimental results and discus-sions are given.
