Answer 2

Explanation:

NIR/SWIR Band Calibration

Water is strongly absorbing in the near- and short-wave infrared wavelengths [26,27]. In the absence of suspended particulate matter, the water reflectance in these bands is negligible and does not make a significant contribution to the TOA reflectance. With this assumption and given that the Raleigh reflectance can be accurately calculated [28–30], the remaining signal can be entirely attributed to aerosol reflectance. The GW94 algorithm uses two bands in the NIR (or alternatively the SWIR [31,32]) in the determination of the aerosol component to the TOA signal. The spectral relationship between the aerosol reflectance in the two NIR/SWIR bands is used to select a candidate aerosol type from as set of precalculated aerosol models. The total signal in the longer of the two wavelengths is used to derive the baseline aerosol reflectance, which is then used in combination with the retrieved aerosol model to extrapolate this aerosol signal into the visible wavelengths. This method has proven very effective for non- or weakly absorbing aerosols.
