Internet Based Data Acquisition

• Real-time Environmental Information Network and
  Analysis System (REINAS)
• real-time data from dispersed sensors distributed
  measurement-gathering environment
• stored in logically integrated but physically
  distributed database via the Internet
• Network Membership
• Monterey Bay network nodes depicted here
• San Diego (SIO and SDSC) are being added
• international nodes in planning

5
Environmental Applications

• La Niña (1998)
• Real-time monitoring
• Data fusion
• Historical archive
• Forecasts
• Coastal Sea-breeze
• Oil Spill Management

Environmental Applications (continued)
Hindcasting
Nowcasting
Forecasting
Real-time data is required for in situ
calibration of numerical models

• On-line replicated storage
• Local data management
• Transparent access

24
Conclusions

• REINAS operational since May, 1996
• Supports a diverse group of users
• A unique laboratory for engineering and
  regional-scale environmental science
• Challenges remain to expand services to current
  and new audiences

25
Conclusions (continued)

• REINAS is a Real-Time Environmental Data Store
• REINAS provides capabilities for relating
• real-time measurements
• historical data
• models / data fusion
• static data (e.g. topography)

26
Conclusions (continued)

• REINAS supports data access and linkage via
  geography and time
• Visualization supports interpretation and
  understanding of the data
• Real-time decision-making is enabled
