1. ACIS Applied Climate Information System ACIS Briefing Greg McCurdy and Grant Kelly Western Regional Climate Center March 15-16, 2006 NPS Climate Inventory Project Meeting Reno, Nevada

2. 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

3. ACIS Application to NPS Metadata Already populated with common NOAA networks NWS-COOP ASOS USHCN SAO / FAA / AWOS HPD Non-Western Region metadata already QCed by other RCCs Allows access to ACIS data products Will allow ACIS products based on non-ACIS data sources to be produced

4. 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 Core components built on industry standard, non-proprietary hardware and software Design allows for integration with legacy systems Data: non-netCDF files Metadata: additional tables can be added without side effects

5. 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 - planned Meta data to support all stations Resolution of inconsistencies

6. ACIS Supported Access Public Users Web interface to standard ACIS products Custom interfaces to selected products Wholesale Users Manual or automated scripting via XML-RPC Access to standard ACIS products ACIS outputs ‘feed’ local products Efficient access to recurring products Product Developer Programs within ACIS environment Develops new products to satisfy needs
