Uncertainties in remote sensing reflectance from MODIS-Terra

A validation analysis of the remote sensing reflectance (RRS) derived from the MODIS instrument on-board Terra (MODIS-T) is conducted with field RRS data obtained at three fixed sites served with autonomous radiometers in the coastal North Adriatic and at two locations in the Baltic Sea, and during oceanographic campaigns in the Baltic, Black and Mediterranean Seas and the English Channel. Validation results show a mean relative difference psi of 10-13% at 531 and 547 nm, and 23-36% at 667 nm. There are much larger deviations in statistics for shorter wavelengths with large psi and bias values in the Baltic Sea. The root-mean-square differences tend to decrease with wavelength from 0.0011-0.0014 sr^-1 at 412 nm to 0.0002-0.0005 sr^-1 at 667 nm. Overall, the uncertainties shown for MODIS-T are very consistent with those associated with MODIS on-board Aqua.
