Table 6: Solar irradiance validation results. Each step represents the amount of data that overcome the validation level. \begin{table}
\begin{tabular}{c c c c c c c c c c c c|c c c} \hline \hline
**Name** & **Data Number per Day** & & & & & & & & & & & & & & **Total of** \\

Table 9 shows the results of the temperature validation procedure. In the first step, missing information was 8.64% on average. _Cerro Paramo_ AWS missed the most information amount, with 16.95% missing data. In the fixed range test, _Guapi_ had data missing of about 11.62%. In the step test, about 35.07% of the data did not pass the validation requirement. Considering the starting values as the base, 57.08% of the data overcame the quality control procedure. Table 10 shows, as Table 7, the record numbers by day. The results indicate that about 57.42% of the days had 88.46% of useful information. Finally, from the total amount of data that overcame the hourly validation test, only 68.03% of data were suitable for feeding the models. \begin{table}
