AQ WG scenario: Wildfire & Smoke

Return back to the listing of AQ WG Scenarios
Return back to the matrix of Transverse Use Cases and Communities Scenarios
 
Brief Description
Test and evaluate the GEOSS Common Infrastructure and AQ Community Infrastructure to share, find, and use distributed data, visualization and analysis services.  The goal is to use information from a variety of sources in order to:
  • understand conditions (both observed and forecasted) related to wildfires and their smoke
  • compare smoke forecasts with satellite and surface observations
  • provide information useful in assessing whether the regional smoke event is considered an "exceptional event"
  • provide information useful for public health applications.
Preconditions

Data providers create standards-based services to their data and register those services with the GEOSS AQ Community Catalog, thereby making those services accessible via GEOSS Clearinghosues. Data analysts and air quality managers find and access those services via GEOSS for subsequent use analyses. The available services are tested to ensure they are active and that they comply with the relevant standards so that they can be reliably used with visualization and analysis tools.

 Service/Component Instances

 AIP-2 Demonstration Storyboard
Pre-AQi. Register AQ Community Catalog
 UC #1 - register resources  Register Catalog
 Mention that community catalog was registered in GEOSS registry
 Pre-AQii. Create and deploy smoke forecast output WCS
 UC #2 - deploy components & services
 Create WCS
 Mention that data providers serve data in standard interfaces, including WCS, OPeNDAP, and others
 Pre-AQiii. Register WMS, WCS in AQ Community Catalog
 UC #3 - Publish, Harvest, & Query Metadata via Clearinghouse  Register WCS   Submit GetCapabilities from CALPUFF WCS
    Submit GetCapabilities from AIRNow WCS
Register OPeNDAP?
 Show how the ISO 19115 metadata document is created for a service using the semi-automated method based on GetCapabilities
 Pre-AQiv. Search for fire occurrence, smoke forecast and air quality observation services
 UC #4 - client search of metadata,
UC #5 - Present Reachable Services and Alerts to Clients
 Search Clearinghouses  
 need to define specific metadata searches for the storyboard
1) Search for community catalog and/or community portal
2) Search for data services

  Pre-AQv. Search for spatial-temporal data analysis tools
 UC #4 - client search of metadata,
UC #5 - Present Reachable Services and Alerts to Clients
 Search clearinghouses for visualization and analysis tools
 ESRI GeoPortal
 Pre-AQvi. Test services for reliability and compliance
 UC #9 - test services
 Test WMS services

ISO 19115 Validator Tool

Scenario Flow
 
 An active wildfire is analyzed for its transportation of smoke and impact on local and regional air quality. Data used in the visualizations and analyses are accessed from distributed services that were identified through GEOSS in the pre-condition steps.
 

 Wildfire & Smoke Scenario Steps

 Transverse Technology Use Cases

 Specialized Use Cases

 Service/Component Instances

 AIP-2 Demonstration Storyboard
 AQ01. A wildfire occurs and an air quality analysts, smoke forecasters and others seeks fire occurrence, smoke and particulate matter data are derived from satellite and surface observations and accessible through SOAP/WSDL and OGC WFS, WCS services.
 UC #6 - interact with services and alerts


 Access fire occurrence observations

Future: Bind - Accessing a Sensor Alert Service, notification send to a Fire detection Workflow service
 Focus on 2007 S. California Wildfires.


 AQ02.   A modeler uses the fire locations to initialize smoke forecast models that are run to predict downwind impacts 1-3 days in the future which indicate a regional smoke pollution event UC #6 - interact with services and alerts

Future: Process - Running a forecast
(--- Workflow & Processing WG)
  No forecast model web servies are available at the moment - forecast models are run offline.
 
 AQ03.   Smoke forecast products are available to the manager/analyst through OGC WCS and OGC WMS
UC #6 - interact with services and alerts
 Access smoke forecast output.
  • Make GetMap request to CALPUFF_WMS
  • Make GetCoverage request to CALPUFF WCS
 Access hourly CALPUFF runs for Oct 21-26, 2007.
 AQ04.   Multiple smoke observation products are available to the air quality manager/analyst through OGC WCS or OGC SOS  UC #6 - interact with services and alerts
 Access smoke observations, including satellite observations of smoke and surface observations of particulate matter concentrations.    Access satellite and surface observations for Oct 21-26, 2007.
 AQ05.    The air quality manager/analyst uses spatial-temporal comparison services to visualize differences and similarities in the smoke forecast products  UC #7 - Exploit Data Visually & Analytically
 

Visualize maps of smoke forecasts.
Visualize maps of smoke observations.
Visualize tables of particulate matter concentration forecasts and observations.
  
 AQ06. The air quality manager/analyst uses the smoke forecasts to assess the need for public health alerts UC #7 - Exploit Data Visually & Analytically  Overlay smoke forecasts with population density and locations of schools and hospitals  
 AQ07. The air quality manager/analyst issues sensor tasking requests to satellite and UAV based sensors to collect new data over the predicted smoke impacted areas, before, during and after the event  
Future: Bind - Accessing a Sensor Planning Service, with scheduling requirements

    
 AQ08. The air quality manager/analyst uses the smoke forecasts to anticipate “exceptional event” waiver requests by States  UC #7 - Exploit Data Visually & Analytically  Visualize smoke forecast in map and time series to identify where and when PM2.5 concentrations are expected to exceed National Ambient Air Quality Standards.
  
 AQ09. After the smoke event, the air quality manager/analyst uses spatial-temporal comparison services between the forecast and observation data (from satellite and surface sensors)
 

 Compare PM2.5 concentrations from CALPUFF with AIRNow surface measurements and OMI AerAbs??
spatially, through frequency distributions of values over an area, and in time series.
  
 AQ10. The air quality manager/analysts uses multi-source observation data to determine whether “exceptional event” waiver requests should be approved.  UC #8 - construct and deploy workflow

Post Conditions
Results from the visualizations and analyses are made available to public health decision makers, air quality managers, air quality modelers, other air quality analysts and the public.
