Gridded Dekadal Water Requirement Satisfaction Index (WRSI) for Africa

Gridded dekadal Water Requirement Satisfaction Index (SRSI) at uniform grid resolution of 0.05° by 0.05° used in Gascoigne et al. (2024).This spatially explicit index is an indicator of crop performance based on the availability of water to the crop during a growing season. Range of WRSI values: < 50: Failure; 50–60: Poor; 60–80: Mediocre; 80–95: Average; 95–99: Good; 99–100: Very Good; 0: N/A.Underlying data at resolution of 0.1°. Underlying data source: Verdin, J., and R.
