WebVIIRS Corrected Reflectance Imagery. The VIIRS Corrected Reflectance imagery is only produced in near real-time. It provides continuity from the MODIS Corrected Reflectance imagery that was developed to provide natural-looking images by removing gross atmospheric effects such as Rayleigh scattering from the visible bands. WebSpecifically, we use Rayleigh-corrected TOA reflectance (ρ rc) in the 443–2300 nm range as input, along with a multilayer perceptron (MLP H ρ rc), for the retrieval of H. More than 78,000 matchup points of ρ rc and H (0–25 m) were used to train MLP H ρ rc , which resulted in a Mean Absolute Percentage Difference (MARD) of 8.8% and a coefficient of …
