Global map of the the average amount of precipitation that falls in the world each year.

Global map of the the average amount of precipitation that falls in the world each year. These long-term averages can be compared to short-term precipitation events to see how much they deviate, which allows to quantify the severity of extreme precipitation events and droughts. Departures from the climatology are a key way of understanding our changing weather patterns. Data is based on NASA’s IMERG Grand Average Climatology and given in millimetres per year, spanning the time period between June 2000 and May 2019. The Scientific colour map ‘navia‘ is used to represent data accurately and to all readers.
