Processing and quality control of observed data :(1) ensure 144 pieces of data every day (every 10min), and mark by -6999 in case of data missing;Air temperature is between 1.1-1.6 and 2.7-3.12, and data is missing due to sensor problems.The soil temperature of 0cm is between 1.3-1.12 and 1.22-4.16, and data is missing due to sensor problems.The temperature of 10cm soil is between 4.5-4.16, and data is missing due to sensor problems.The station was demolished after April 16;(2) excluding the time with duplicate records;(3) data that obviously exceeds the physical significance or the range of the instrument is deleted;(4) the part marked with red letter in the data is the data in question;(5) date and time have the same format, and date and time are in the same column.For example, the time is: September 10, 2015, 10:30;(6) the naming rule is: AWS+ site name.
