Air Quality & Health Scenario

Scenario Overview

• The AQ Scenario envisions multiple types of AQ observations…• satellite observations of AQ and meteorology• in-situ, ambient observations • models of meteorology and chemical transport • other: emissions data, fire observations, LIDAR, etc.

…being registered, discovered and accessed via GEOSS and used to inform diverse decision-makers: Air Quality Managers, Policy-Makers, and the Public.

• Scenario community-developed ; AIP participation diverse (next slide)

• Initial sub-scenario testing AIP Use Cases describes a Wildfire/Smoke event

Challenges

• Persistent, standardized AQ data network

• Interface to GCI: Community Catalog, Portal

• Implementing scenarios which can integrate the offerings using GCI-compatible Service Oriented Architecture

Where are we now?

Where do we want to be?

How to get there?

Automatically extract discovery metadata from Capabilities & KML

CSW – Queriable Fields for Discovery WCS – Data Access Service Extensions

Collaboration with UNIDATA & GALEON

4D Grids for Models, Satellite Data

netCDF – CF Convention

Station Time Series (STS) for Point Data

netCDF – STS Convention

Community Portal• A user interface between GEOSS CGI and AQ Community Catalog

• A content aggregator and connector

• Help air quality data/service providers and data/service users make use of the GEOSS Common Infrastructure

• Forum for dialogue among the community in shared interests in air pollution events, analysis tools, models, datasets, etc.

Development Portal: http://128.252.167.3

Help in finding and using search, visualization and analysis tools

Latest data analyses, publications, etc

Extra Slide:AQ & H Smoke Scenario

Scenario Actors, Services, and Products Transverse Tech Use Cases

 AQ01. Fires are detected through satellite and surface observationsBind - Accessing a Sensor Alert Service,

notification send to a Fire detection Workflow service

 AQ02.   Based on fire locations, smoke forecasts (processing services) are run to predict downwind impacts 1-3 days in the future which indicate a regional smoke pollution event

Process - Running a forecast (--- Workflow & Processing WG)

 AQ03.   Multiple smoke forecast products are available to the manager/analyst through OGC WCS

Bind - Accessing a Model

 AQ04.   Multiple smoke observation products are available to the air quality manager/analyst through OGC WCS or OGC SOS

Bind - Accessing a Product

 AQ05.    The air quality manager/analyst uses spatial-temporal comparison services to analyze differences and similarities in the smoke forecast products

Visualize - Analysing forecast products(--- Portal & Desktop applications WG)

 AQ06. The air quality manager/analyst uses the smoke forecasts to issue public health alerts

Publish a rendering service (WMS...) ?

 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

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

TBD

 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) to assess the accuracy of the models

Visualize - (--- Portal & Desktop applications WG)

 AQ10. The air quality manager/analysts uses multi-source observation data to determine whether “exceptional event” waiver requests should be approved.
