System Architecture

• Takes advantage of the internet and the latest
  web tools
• Distributed/Synchronized data bases
• Redundancy built in to handle system failures
• Flexible interface can link to part or all of the
  ACIS product suite
• Object-oriented programming design allows for
  extension of capabilities

State-of-the-Art Techniques

• netCDF Data Structures
• PostgreSQL RDBMS (for metadata)
• Python and JAVA programming languages
• Quixote (web application server)
• CORBA compliant network software
• Open Source software components

4
Integrated Data Sources

• Time-integrated datasets
• Coop-3206, 3200 (final, preliminary, keyed), and
  NOAAport (SHEF, DSM, local)
• 9641 (normals)
• 3280 (surface airways)
• 3220 (monthly) planned
• Integrated with other data sources
• Mesonets AWDN - Operational
• RAWS, SNOTEL, SCAN, USGS, CoCoRaHS - planned
• Meta data to support all stations
• Resolution of inconsistencies

5
Quality Assurance Programs

• Built on open architecture concept with high
  speed algorithms
• Procedures tuned to site and season
• Refined interpolation leads to tighter confidence
  intervals
• Estimates provided but original data retained
• Real time data are manually QCd by RCCs
