Quality Checks on Continuous Rainfall Records: A Case Study

The records obtained from the rain gauge stations may contain missing information or other forms of human or machine errors, which might hamper with analysis or lead to incorrect inferences drawn from the data. It is pertinent that the data should be screened and suitable quality checks be applied on the records before using them for hydrological analysis. In this paper, the statistical quality checks suitable for checking the quality of hourly time history of rainfall from a site are discussed along with example applications as a case study.
