LAC Dryland Atlas

Atlas of Arid, Semi-arid and Subhumid Zones of Latin America and the Caribbean.

This maproom shows the analysis of Aridity, Climatic Agressivity, Seasonality and Monthly Deficit of the countries in Latin America and the Caribbean, with a focus on the drylands. The complete analysis is described in Verbist et al. (2010).
