GDO Meteorological Drought Tracking (version 1.0.1)

Description

This indicator outlines persistent anomaly conditions of low precipitation, as discrete events in space and time, at the global scale and at near real-time, every ten days. By providing information on the duration and spatial extent of droughts, it allows for a structured and well-defined analysis of individual droughts, e.g. to follow evolution in space-time, to associate impacts, to link with other natural hazards, to search for patterns, etc. Derived from the ERA5 (fifth generation) reanalysis, drought events are identified with a three-dimensional density-based clustering algorithm (DBSCAN) on SPI-3. Events are classified as "consolidated" if their outline at a given ten-day period is stable through updates, or "provisional", when the spatio-temporal outline is likely to change with further updates. The technical details describing the methods for the computation of the indicator can be found in Cammalleri, et al. An event-oriented database of meteorological droughts in Europe based on spatio-temporal clustering. Sci Rep 13, 3145 (2023).
