Data System Profiles

 Visualization/AnalysisReusable Tools and Methods
3D-AQSNot GivenNot Given
AIRNowPublic visualization is via animated GIF maps, offered on the AIRNow.Gov website. Dynamic visualization may be accomplished via the Navigator tool on AIRNowTech. In addition, AQI current conditions and forecasts are available as KML and can be used for Google Earth mashups ( Gateway’s use of standardized web services makes those solutions reusable.
CASTNETConcentration maps for the Eastern and CONUS regions are shown on the CASTNET website. Deposition trends plots, changes in meteorology, and ozone concentrations are shown for each site on the CASTNET website. Additional publications with supporting visualization and analysis are also available on the website.Not Given
CMAQNot GivenNot Given
EMFMIMS Analysis Engine embedded in EMF. Uses PAVE in SMOKE run scripts to generate plots during SMOKE runs. Hoped-for links to VERDI, but no specific plans.Not Given
EPA AIRQuest Data WarehouseNot GivenNot Given
EPA AQSNot GivenExchange Network web services
ESIPNot GivenUse of wiki, portals, catalogs. Guidance on best practices. Promotes web services and service oriented architecture approaches to reuse.
GIOVANNIPlot Types for Single Parameters:
  • Area plots of time-averaged parameters
  • Time series plots of area-averaged parameters
  • Meridional averages
  • Zonal averages
  • Vertical profiles
  • Longitude-latitude-pressure-time cross sections

Plot Types for Multi-Parameter Intercomparisons:

  • Area plots of overlain time-averaged parameters
  • Time series plots of area-averaged parameters
  • Difference plots
  • Scatter plots with regression
  • Temporal correlation maps

Animations Climatology and anomalies ASCII output for maps and plots

Web services for downloading subsetted data
GrADS, IDL, Python, Perl Aggregation, statistics
GeoWebA user of the Geoweb connects to the Server using a web browser such as Firefox or Internet Explorer. This permits searching for data files and viewing of metadata about each file. After a file of interest is located, the data can be visualized on-screen provided that a tool such as World Wind Geo, Google Earth, NASA’s World Wind, or ArcGIS Explorer are installed on the workstation. For a survey of map visualization tools for use within the EPA, see The World Wind Geo tool is a free download from Google Earth Pro is available within the EPA via Agency-wide license. See for information on obtaining the license. NASA’s World Wind is a free download from ArcGIS Explorer is a free download from Given
HEImaps of sites, interpolated spatial concentration plots, time series graphs and pie chartsNot Given
NARSTOPlots are provided for most currently archived data, and are sometimes generated for previously archived data.The Data Exchange Standard is reasonably flexible and it can be used for a wide variety of air quality data.
NASA Atmospheric Science Data CenterNot GivenFully scalable architecture.
NEISGEIMashup web applications for spatial, temporal and other charting visualizations and analysis.Modular design for application development.
RSIGYes. RSIG provides a simple and quick interactive visualization of all data overlaid together on an appropriate map.RSIG components include an applet and set of documented WCS server applications and powerful subset and converter programs - all of which are freely available and accessible by others. This applet/server/subset method will be updated as needed to access additional data as requested by users and prioritized by the Principal Investigator.
Unidata IDD Data SystemUnidata supports a suite of analysis and visualization tools (GEMPAK, McIDAS, Integrated Data Viewer) that can be employed by users for analysis and visualization. Unidata also supports middleware such as the netCDF and the THREDDS Data Server that enable users to access data from remote servers via standard protocols for analysis and display using tools other than those provided by Unidata.Nearly all of Unidata's tools and software are freely available in addition to the data streams.
VIEWSA wide variety of general-purpose visualization and analysis tools are available on the VIEWS website for exploring the data and producing graphs, charts, maps, and formatted data files. Specialized tools allow users to browse and analyze time series, visibility trends, spatial patterns, temporal aerosol profiles, chemical species composition, light extinction budgets, back trajectories, estimated natural conditions, visibility projections, glide slope plots, emissions inventories, weighted emissions potentials, and model performance evaluations. All tools have been designed with common user interface components and are being re-factored with a Service Oriented Architecture approach to allow them to function as web services.
