Comparision between observed and generated mean daily precipitation and maximum and minimum temperature in the time step for the Dangila station.
a) precipitation (mm), b) maximum temperature (°C), and c) minimum temperature (°C). Bega season = October–January, Belg season = February–May, and Kiremit season = June - September.

Percentage change in monthly, seasonal, and annual precipitation for the period 2010-2099 as compared to the baseline period (1990-2001) at Dangila station.
a) A2a scenario and b) B2a Scenario. Bega season = October–January, Belg season = February–May, and Kiremit season = June -September.
