Results obtained from the tank experiments on six different days showed that surface reflections contributed 5-66% to total upwelling water radiance at nadir and introduced an error of 20 to 54% in measured water reflectance. The coefficient of variation for the correction factor was estimated as 0.92, which indicated that correction factor was highly variable. The model was developed with diffuse light condition, sun altitude, wind speed and wavelength as input variable and correction factor as the output under lab conditions. The R2, RNS2, and RMSE were found to be 0.96, 0.96, and 0.0032, respectively for testing of the model on different set of data. Sun attitude and wind speed were the two major factors affecting correction factor at any VIS-NIR wavelength.Introducing a Mini-Catamaran to Perform reflectance Measurements Above and Below the Water Surface.
