List of data provided

---------------------------------------------------

The data is annual June-September (JJAS) precipitation means for:

- Observed anomalies over 1920-2018 respect to 1955-1984 average over the Sahel (lon: 20°W-30°E, lat: 10°N-20°N)

- Model anomalies over 1920-2018 respect to 1955-1984 average over the Sahel (lon: 20°W-30°E, lat: 10°N-20°N)

- Observed precipitation difference 1980-1990 mean - 1950-1960 mean

- Model differences between 1.5x and 0.2x aerosol scalings over 1955-1984

- Trends in relative precipitation anomalies (baseline 1955-1984) over decline (1955-1984) and recovery (1985-2014) period over the Sahel (lon: 20°W-30°E, lat: 10°N-20°N)
