About this data
The dataset provides a global assessment of changes in average precipitation by providing the precipitation anomaly and provides a global assessment of extreme precipitation through the use of two precipitation indices, i.e. very heavy precipitation days and frequency of extreme precipitation events. Exposure indicators to extreme precipitation have been prepared jointly by the Organisation for Economic Co-operation and Development (OECD) and the International Energy Agency (IEA). Please see the working paper for a more complete description of the methods. The datasets span the period 1979-2022, depending on data availability and are the result of the use of a variety of geospatial data sources as referenced in the Working Paper. The dataset has a global coverage on a national level; on the sub-national TL2 level (i.e. large subnational regions) results are reported for all OECD countries as well as for Argentina, Brazil, China, India, Indonesia and South Africa. A number of aggregates are included: Euro area, European Union, Advanced economies, Emerging market economies, G7, G20, OECD, OECD Europe, OECD Asia Oceania, OECD Americas and the LAC region.
