A new multiscalar drought dataset, SPEIbase, made available to the scientific and management community is presented. The multiscalar of the dataset allows finding the appropriate time scale of interest for a specific application, so potential uses of the dataset range over a wide variety of disciplines. The dataset (in three file) is distributed under an open license. Further work includes updating the dataset past December 2006, depending on the data availability.
