### Relations and Similarity Analysis for AT, RH, SR, BP, PR, and SD
At the same time, the acceptable PS values (\(>\)75%) were revealed in all the station pairs of G1 and G2, and one pair (i.e., C5 vs. JP213) of G4 groups. Regarding SR, strong relations, such as r-values (\(\geq\)0.85) and AAE (in the range 16.41 and 63.39 \(W\)/m\({}^{2}\)), and unacceptable similarities, such as PS value (\(\leq\)32.38%) were observed. Regarding BP, data for only one station pair (i.e., C4 vs. JE323 in group G1) was available; where strong relations, such as r-value (=0.98) and AAE (=1.82 kPa), and unacceptable similarities, such as PS value (=0%) were revealed. Regarding PR, there were two station-pairs (i.e., C1 vs. C4 in group G1, and C5 vs. JP213 in G4); where moderate-to-strong relations, such as \(r\)-_values_ (\(\geq\)0.69) and AAE (\(\leq\)22.71 mm), and unacceptable similarities, such as PS value (\(\leq\)32.12%) were observed. Regarding SD, data for only one station-pair (i.e., C1 vs. C4 in group G1) was available; where strong relations, such as r-value (=0.95) and AAE (=2.83 cm), and acceptable similarities, such as PS value (=76.40%) were found. G3 Group: Among all seven groups, G3 was the largest one comprising 19 station pairs where the weather parameters of AT, PR, RH, BP, SR, and SD were measured. The station pair-wise relations and similarity measures are given in Table 3. In the case of AT, strong relations, such as r-values (\(\geq\)0.97) and AAE (in the range 0.56 and 2.72 \({}^{\circ}\)C) for all the station pairs, and unacceptable similarities, such as PS value (\(\leq\)44.82%) for all the stations except the C3 vs. JP104 pair (with having an acceptable similarity with a magnitude of 84.80%), were found. Regarding RH, strong relations, such as r-values (\(\geq\)0.80) and AAE (\(\leq\)9.14%), were observed for all the station pairs. At the same time, the acceptable PS values (\(\geq\)75%) were witnessed for 14 out of 19 station pairs. Regarding SR, strong relations, such as r-values (\(\geq\)0.85) and AAE values (\(\leq\)70.79 W/m\({}^{2}\)), and unacceptable similarities, such as PS values including \(\leq\)64.79% were seen. Regarding BP, data for only one station pair (i.e., C3 vs. JE306) was available. Both moderate relations, such as r-value (=0.66) and AAE (=5.97 kPa), and acceptable similarities, such as PS value (=82.27%) were found. Regarding PR, there were three station pairs (i.e., C3 vs. JP107, C3 vs. JP311, and JP  
JP 311) available. Moderate relations, such as r-values (between 0.31 and 0.57) and AAE (\(\leq\)1.20 mm), and unacceptable similarities, such as PS value (\(\leq\)2.73%) were seen. G5, G6, and G7 Groups: The outcomes of relation and similarity analysis are presented in Table 4 for G5 (i.e., L1, L2, R2, and JE306), G6 (i.e., C2, C4 and JE323), and G7 (i.e., JE308 and JE312) for the relevant weather parameters, such as AT, PR, RH, SR, BP, and SD. In the case of AT, strong relations, such as r-values (\(\geq\)0.98) and AAE (in the range 0.88 and 2.20 \({}^{\circ}\)C), and unacceptable similarities (\(\leq\)68.79%), were observed for all station pairs. Regarding RH, strong relations, such as r-values (\(\geq\)0.86) and AAE (\(\leq\)7.53%), and acceptable similarities, such as PS values (-75%) were found for all the station pairs. Regarding SR, strong relations, such as r-values (\(\geq\)0.84) and AAE (in the range 23.10 and 73.52 W /m\({}^{2}\)), and unacceptable similarities, such as PS value (\(\leq\)36.93%) were observed. Regarding BP, weak-to-moderate-strong relations, such as r-values (=0.14, 0.37, and \(\geq\) 0.77) and AAE (\(\geq\)7.86 kPa), and acceptable similarities, such as PS value (\(\geq\)92.85%) were witnessed for three station pairs. For example, R2 vs. JE306 in G5, C2 vs. JE323 in G6, and JE308 vs. JE312 in G7. However, two station pairs of G6 (i.e., C2 vs. C4 and C4 vs. JE323) showed very weak similarity (\(\leq\)0.44%).
