◎ Dataset of daily climate data from Chinese surface stations for global exchange (V3.0)

"The dataset (V3.0) of daily values of climate data from Chinese surface stations for global exchange" includes such daily data as pressure, temperature, precipitation amount, evaporation amount, relative humidity, wind direction, wind speed, sunshine duration, and 0cm surface soil temperature from 194 stations in China since January 1951. The data volume is 1.89 GB.

  • Quality
  • After quality control, the quality and integrity of various elements in 1951-2010 has been improved, relative to the similar data and products that were published previously, availability of various weather elements is generally above 99%, and correct data rate approaches to nearly 100%. The dataset of daily values of climate data (V3.0) from Chinese surface stations for global exchange is mainly based on the rectified basic dataset of CLIMAT data files (A0/A1/A) from the national level surface stations in 1951-2010, which have been archived under the project for building up basic surface meteorological data. During the work by CMA from March 2011 to June 2012 to build up such basic surface data, repeated verifications and quality controls were targeted to the observational data in CLIMAT files from the national level stations in 1951-2010, during which a large number of wrong data were rectified, and the missing digitalized data were supplemented, and this work has improved the data quality noticeably. Furthermore, in the process of dataset production, the weather element data in 1951-2010 in the dataset has been under quality control, all suspicious and incorrect data have been rechecked and rectified manually, and eventually all element data are flagged with quality control codes.
