Projections of future surface air temperature and precipitation for the Middle Awash River basins in Ethiopia using a statistical downscaling model (SDSM)
Author(s): Tesemash Abebe*
In recent decades, climate change has become a major environmental and socioeconomic challenge in Ethiopia. The study used the statistically downscaled daily data in 30-year intervals from the second generation of the Earth System Model (CanESM2) under three Representative Concentration Pathways (RCPs): RCP2.6, 4.5, and 8.5 for three future time slices; near-term (2010-2039), midcentury (2040-2069), and end-century (2071-2099). The observed maximum and minimum temperature and precipitation values are a good simulation of the modeled data during the calibration and validation periods using the Pearson coefficient (R), the correlation coefficient (R2), and the Nash-Sutcliffe efficiency (NSE). In three sampled stations (Awash Arba, Shewa Robt, and Erer), there is a minor difference between all considered scenarios during the 2020s. The results of maximum and minimum temperature are expec..
