Abstract:
The Intensified Automatic surface Weather observation System (IAWS) is becoming accomplished with the enhancement of the observation system in China. Local IAW S network has been set up in many areas and much attention has been paid to the application of IAWS data. Because of the special characteristic of IAWS, the appl ication is postponed by the problem of data quality in some degree. In order to facilitate the study on IAWS data Quality Assurance(QA) procedures in our countr y, three aspects are analyzed in this paper. First, the speciality of IAWS is analyzed by comparing the characteristics of IAWS data and Conventional Manu al surface eather observation System (CMWS) data.Second，the experiences of building up the IAWS QA procedure in other countries are introduced as reference. At las t, the differences are analyzed between the IAWS QA and CMWS QA, and the key as pects and problems are pointed out to be notified during the setup of IAWS QA. R esults show that the IAWS QA is different from CMWS QA in some aspects. More att ention should be paid in management of IAWS operation, the automatic quality co ntrol at station level, as well as manual quality control and quality monitoring .
