I have a huge series of raster maps in which the pixels vary their value (from 0 to 100) from map to map. Then I have a watersheds map (i.e. a map divided in subareas, shape or raster). How could I do to count how many time in each watershed (subarea) x pixels exceed a certain threshold (for example at least 3 pixels beyond the value of 80)?

Hi Elana,
You could run the Extract by Mask tool to extract the raster area intersecting the watersheds. Then, run the Extract by Attributes to see how many pixels are in the threshold (i.e. Value > 80).
