What is it about?
The SADA is an annually-resolved hydroclimate atlas in South America that spans the continent south of 12°S from 1400 to 2000 CE. Based on 286 tree ring records and instrumentally based estimates of soil moisture, the SADA complements six drought atlases world wide filling a geographical gap in the Southern Hemisphere.

Why is it important?
This study addresses a critical gap in our understanding of the recent hydroclimatic changes in South America by recreating 600 years of South American hydroclimate variability. We noted that widespread droughts and extreme rainfall events have become more frequent over the last 60 years on the continent. Our research offers the unique possibility of putting these recent unprecedented hydrologic extremes in a 600 years context.
