Abstract: The Parameter Weighting Operation is employed in Giovanni-3 so that one parameter (SDS) is weighted by another when computing any average (or similar statistical quantity such as standard deviation). The averaging can be conducted either spatially or temporally.
Note: In Giovanni-3, Parameter Weighting is currently only applied to the computation of the MODIS &Aerosol Small Mode Fraction& which is weighted by Aerosol Optical Depth (AOD). In this case, a valid weight is defined to be any AOD ≥ 0. (Note that this definition is equivalent to resetting any negative measurement of AOD to 0 for the purpose of the weighting operation.)
