Current Project Objectives

The project’s focus is on criteria pollutants and toxics because of their availability and accessibility.

Recommend and demonstrate to the CEC approaches for the comparability of techniques and methodologies for data gathering and analysis, data management, and electronic data communications for promoting access to publicly available electric utility emissions

Identify, collect, and review existing sources of electric generating utility (EGU) emissions and activity databases, and provide a summary of the state-of-science

Build a prototype web browser tool to query, retrieve, and explore emissions data from heterogeneous databases

Guiding Principles

Distributed. The data sources remain distributed and in the control of their providers. The data are dynamically accessed through the internet rather than through a central repository.

Non-intrusive. Data providers are more likely to participate if joining an integrated network does not impose new or additional burden on them.

Transparent. The distributed data should appear to originate from a single database to the end user. One stop shopping and one interface to multiple data sets are desired without required special software or download on the user’s computer.

Flexible/Extendable. An emissions network should be designed with the ability to easily incorporate new data and tools from new nodes joining the network so that they can be integrated with existing data and tools.

The controllers and map image view can be linked and assembled in a web page. Changing the settings of a controller changes the URL of the map image and updates the web page.

The web page can be constructed using standard web application programming languages, such as JavaScript and ASP.

Distributed Fire Data Sources

Numerous state, regional, and national fire related databases and online access applications exist. The challenge is to bring them together, on-the-fly, without requiring substantial changes to the underlying systems.

Also need to access data sources that are not “Web-ready”.

MissionEstablish and continuously improve science-based end-to-end processes that increase the quality and value of scientifically sound Earth science information provided in a timely manner by a federation of partners collaborating to improve their collective services

Strategic Goals 1. Serve as facilitator and advisor for the Earth science information community. 2. Promote efficient flow of Earth science data from collection to end-use. 3. Improve quality and usability of Earth science data and information systems. 4. Expand the use of Earth science information – get it to the decision-makers.5. Educate the public about Earth science and science information systems.

ESIP Federation Clusters

Clusters are formed by a group of ESIP members to address a particular problem of interest

Intended to promote informal, easy exchange of information among partners

Evolution of an AQ Cluster

Air Quality is one of 12 Applications of National Priority as defined by NASA and is one of 5 National Application Areas most frequently selected as an area of interest by ESIP members and stakeholders.

January 2005 An air quality focus group met during the 2005 ESIP Winter Meeting to discuss how ESIP might play a role in advancing the use of earth science data in air quality management. Interest is high within ESIP and air quality is recommended as a new ESIP cluster.

March 2005 A draft strawman report is generated that outlines the formation of an ESIP AQ Cluster. The report is circulated among potential stakeholders within EPA, NOAA, and NASA. Interest within EPA is high.

March 2005 ESIP meets with ESRI and EPA/ORD and EPA/OEI to discuss ideas for an ESIP Federation Portal. Air quality is identified as the area of focus for the demonstrating and developing a portal and the AQ Cluster is asked to assist in developing the AQ component of the portal.

Today An objective in presenting the AQ Cluster today is to gain feedback, recruit participants, and conceptually enhance the goals of the cluster.

Information flow networks being developed

FASTNET (existing project) – an established real time project for real time access and synthesis of surface, satellite, and model data that could be strengthened as part of the AQ Cluster

ESRI/ESIP Portal (under development) – Develop web resource for consolidated access to air quality related data products and visualization/analysis tools. Also will provide collaboration tools to foster development of other AQ information chains.

Supplement VIEWS with satellite data (being planned)- Provide convenient mechanisms for semi-automated access, processing and synthesis of satellite derived aerosol parameters coinciding with surface air quality monitors for comparison in VIEWS system.
