Observation data processing and quality control:
（ 1) Ensure 144 data every day (every 10min). In case of missing data, it shall be marked by - 6999; 10m wind speed is marked with - 6999 before November 12, 2013 due to instrument problems
（ 2) Eliminate the time with duplicate records
（ 3) Data that is obviously beyond the physical meaning or beyond the range of the instrument are deleted
（ 4) The part marked in red in the data is questionable data
（ 5) The format of date and time is unified, and the date and time are in the same column. For example, the time is: 10:30, September 10, 2013
（ 6) The naming rule is: AWS + site name
