LAC Drought Atlas

Historical drought frequency analysis for the countries of Latin America and the Caribbean.

This maproom shows the results of the Regional Frequency Analysis using L-Moments. The complete analysis is described in Nuñez et al. (2010).

The Drought Atlas was developed in colaboration with the International Center for Integrated Water Resource Management (ICIWaRM) and the European Joint Research Centre (JRC).

Regional workshops were organized with support from the Flanders-UNESCO Trust Fund (FUST) and in collaboration with the EU-funded projects Euroclima and RALCEA.
