Air Temperature Estimation by Using Artificial Neural Network Models in the Greater Athens Area, Greece

Figure 2

Scatterplots of observed versus estimated 𝑇 values in (a) Nea Smirni (S1), (b) top (alt. 1086 m) of Pentelikon Mt. (S2), (c) middle (alt. 796 m) of Pentelikon Mt. (S3), and (d) Peristeri (S5) in the GAA, Greece, during winter of 2009-2010. 𝑇: air temperature, alt.: altitude, Mt.: mountain, GAA: greater Athens area, MLP1: multilayer perceptron model with 𝑇 as input parameter, MLP2: multilayer perceptron model with 𝑇 and time of the corresponding 𝑇 as input parameters, 𝑅² = coefficient of determination, MAE=mean absolute error, and 𝑃<0.05.
