Service Description: The “Water and Wetness Probability Index” (WWPI) layer is an additional product for expert users and indicates the occurrence of water and / or wet areas (with saturated soil moisture content) during a prolonged part of the year over a number of years. The index is derived from support layers calculated from seasonal compositesin which each pixel in a given layer is classified as “dry”, “wet” or “(open) water”. Based on the same seasonal composites as applied for the classification of water and wetness, the WWPI is derived for each “column” of pixels in the stack. The WWPI is calculated according to the number of WATER and WET occurrences, the latter with a weighting factor of 0.75 (this value was confirmed after the analysis of the streamlining results), divided by the total number of valid observations (sum of WATER, WET and DRY occurrences). The resulting product assembles the water and wet occurrence as an index on a scale between 0 (only dry observations) to 100 (only water observations).
