Objective

• Make data quality information easy to use for the water cycle community
  • Expert and non-specialist users alike
  • Human and machine users alike
• Connect users seamlessly to best practices in data quality handling, i.e., the science team recommendations for quality screening (filtering)
• Enable higher and more correct utilization of data quality indicators in data analysis

Quality Screening Process

Approach

• Implement easy-to-use Web Service
  • Users invoke as a Universal Resource Locator (URL)
  • Encodes science team recommendations into service
• Describe quality fields and recommendations in an ontology for extensibility, reusability and machine readability
• Support both server-side and user-side screening
  • Server-side screens data before sending
  • User-side supplies quality mask and portable tools for screening on the user’s computer
