The Network Enabled Verification Service (NEVS): Evaluating weather forecast quality in NextGen

The NextGen 4-D Weather Single Authoritative Source (SAS) will require an ongoing evaluation of weather data quality, with emphasis on the air traffic planning processes and the impact weather has on safety and efficiency. The Network Enabled Verification Service (NEVS), currently under development at NOAA's Earth System Research Laboratory (ESRL), will fulfill this SAS requirement, incorporating innovative user-specific verification concepts with an operationally robust engineering solution.

The complex data analysis provided by NEVS has forced a break from the traditional stovepipe architectures found in most legacy verification systems. The NEVS architecture, adopting an approach compatible with the NextGen Network Enabled Weather (NNEW) Service Oriented Architecture (SOA), defines three distinct layers: production, integration, and analysis. The integration layer, built on a relational data model, enables dynamic data mapping driven by the user problem domain and sophisticated data joining. This unique aspect of NEVS allows data analysis across traditional weather and ATM boundaries.

This paper will explore the scientific concepts that are fundamental to NEVS, describe engineering advances of NEVS, demonstrate the current capabilities of NEVS, and outline development plans for IOC.
