Bias correction of satellite and reanalysis products for daily rainfall occurrence and intensity

John Bagiliko, David Stern, Francis Feehi Torgbor +3

In data-sparse regions, satellite and reanalysis rainfall estimates (SREs) are vital but limited by inherent biases. This study evaluates bias correction (BC) methods, including tr…

Validation of satellite and reanalysis rainfall products against rain gauge observations in Ghana and Zambia

John Bagiliko, David Stern, Denis Ndanguza +1

Accurate rainfall data are crucial for effective climate services, especially in Sub-Saharan Africa, where agriculture depends heavily on rain-fed systems. The sparse distribution…
