DataData

Viewed in context of WMO World Weather Watch Optimize the integration of GOS, GTS and Data-processing System

1. Specifications for data representation (codes, exchange formats, database design, storage of observational data)

2. Designing proper procedures in the area of data processing and telecommunications, allowing members appropriate sets of data.

3. Monitoring AMDAR operations and the quality of basic data and output products
