Figure 4.
The top charts display raw and Mean Deviation Correction adjusted tenth percentiles, where the correction smooths the monthly variations and aligns model data more closely. The bottom charts show raw and adjusted ninetieth percentiles, with clear reduction in extreme precipitation differences between models. Observations and outputs from A C C E S S C M 2, E C Earth 3, H a d G E M 3 G C 3 1 L, M I R O C E S 2 L, and M P I E S M 1.2 H R models are compared. The adjustment improves agreement across models throughout the months, as shown on the horizontal axis, while the vertical axis indicates precipitation in millimetres per day.Performance of multiplicative delta change (MDC) bias correction technique on 10th and 90th percentiles of CMIP6 precipitation datasets over southern Ethiopia
