*3.1. Assessment of the Quality of the Simulated Climate Data for the Baseline Period*

The monthly averages of P (mm), Tmax and Tmin (◦C), and Nr (MJm<sup>−</sup>2) were recorded on the two meteorological stations of BBA and Setif departments, during the BP (1981–2010) are indicated in Figure 2. These recorded monthly averages are compared with those simulated by the climate model ICHEC\_KNMI for this same BP. Additionally, in Figure 2, the RMSE values for each of the above four climate parameters are indicated. Thus, for the BBA station, Tmax, Tmin, and Nr are simulated with great precision as shown by the low values of their respective RMSE 1.998 ◦C, 2.029 ◦C, and 2.193 MJm−2, (Figure 2a,c,g). However, the P were simulated with less precision (RMSE = 6.674 mm), as indicated in Figure 2e. Thus, for the months of the period from October to March, the simulated P are overestimated. However, the simulated P for the months April to September are underestimated compared to the P recorded on the BBA station during the BP. Figure 2b,d,h show that Tmax, Tmin, and Nr, respectively, at the Sétif station, are simulated with good precision as indicated by the low values of their respective RMSEs (0.439 ◦C, 1.381 ◦C, and 2.785 MJm−2). However, the P simulated with relatively lower accuracy as shown in Figure 2f and the relatively higher RMSE value (9.875 mm).
