AIP Phase 2 Call For Participation: VIEWS/TSS Response Overview
GEO Architecture Implementation Pilot – Phase 2 (AIP-2) Kickoff Workshop
NCAR Mesa Laboratory, Boulder, Colorado
September 25-26, 2008
VIEWS
The Visibility Information Exchange Web System
http://vista.cira.colostate.edu/views
 Provides integrated online access to:
 Monitoring data: from over 3 dozen networks
 Modeling data: from a variety of modeling scenarios
 Emissions data: inventories and summaries
 Satellite data: MODIS, CALIPSO, Aqua, Terra, GOES, etc.
 Serves as the primary source for:
 IMPROVE Aerosol and Optical data
 IMPROVE Regional Haze Rule data
 IMPROVE Special Studies data
 Has about 1200 registered users from over 300 organizations, institutions,
universities, and companies
TSS
WRAP Technical Support System
http://vista.cira.colostate.edu/tss
 Built upon the database and software infrastructure of VIEWS
 Provides consolidated online access to:
 Regional technical data, planning guidance, and analysis results
 Decision support for the development of SIPs and TIPs
 Source apportionment and visibility projections tools
 Ongoing tracking and assessment of emissions control strategies
 Documents the technical methods used in implementation plans

Source Apportionment
 Mass source apportionment by source
category and region
 From regional photochemical model with
comprehensive emissions inputs
 Species mass for various time periods –
directly comparable to monitoring data

Metadata Management Tools: Monitoring Site Metadata
Metadata Management Tools: Exceptional Events
Exceptional event metadata (such as fires, dust
storms, etc) is stored and dynamically associated
with data at run time in order to better inform the
user about the context of the data.
Metadata Management Tools: Data Advisories
Data Advisories document interesting findings from the integrated database such as
data anomalies, potential problems, and new uses for the data.
These advisories are stored as metadata in the VIEWS database and dynamically
associated with data and products. When a user selects data, the systems checks
for any advisories relevant to the data selected and attaches them to the output.
Goals for Participation in GEOSS AIP
• Better awareness of community interoperability efforts
• Better understanding and use of proposed GEOSS standards
• Standardization of intra- and inter-system data exchange
• Leveraging and reuse of existing resources through service-chaining
• Increased value of existing development investments
• Improved resource availability and decision-making for end users
• Standardization of Codes and Flags (possible?):
• SO4
