This includes the fields time_step, which is merely informative, and describes the time interval between two consecutive values, and the lower_time_bound and upper_time_bound, which are the values that should be summed to each verification time to unequivocally delimit the time span encompassed by each value. In essence, the dictionary is a comma-sepparated text file (csv), that by default is identified with the same name than the argument dataset of the loadSeasonalForecast function. The dictionaries for the currently available datasets are included in the ecomsUDG.Raccess package, within the ''dictionaries'' folder.
