Data Source: RP5 website

Download Data style: select UTF-8 encoding. unzip to get xxx.csv file after download

Calculation target: Contains the average temperature per month and the average temperature of each day of the current month, named by month and stored in the corresponding file.

Data format:

Attention:

1. daily average temperature includes times: 02,08,14,20. The initial data contains no use when 05,11,17,23 in the time.
2. There may be missing times for some dates in the file, and if so, the day is not calculated. The total number of days to calculate the average monthly temperature does not include this day of absence.
