# Forecasting Daily Temperatures with Different Time Interval Data Using Deep Neural Networks
## 4 Data
### Basic Statistics
#### 4.3.1 Hourly Data  
Tables 8-10 show the basic statistics for the hourly unit data for the three selected regions; these basic statistics show clear differences between the three regions. In particular, the temperature, amount \begin{table}

Table 7: Missing values for solar radiation. of water precipitation, and atmospheric pressure in Seongsan and Daegwallyeong clearly show such regional characteristics. We note here that the solar radiation quantity in Seongsan was not measured; therefore, in this experiment, there is one less variable than other regions. \begin{table}
