selected Motivations from IWDW participants

1.       Discuss how IWDW have responded to input from air agencies, FLMs, and EPA regions in the West about MPE

2.       Display IWDW tools and functionality

3.       Understanding plans by ORD (and OAQPS) to develop modular and transparent MPE tools

can add Motivations for TCEQ

Motivations as defined by EPA

The atmospheric observation and modeling communities generate enormous volumes of environmental data, and efforts to improve both access to that data and effective web-based analysis tools are ongoing. There are several components to a successful web-based data access and analysis solution including data storage, retrieval, query and visualization. Storage and retrieval of these large datasets require solutions that take into account the data volume, access frequency, transfer speed, fixed cost of infrastructure, etc.

Moreover, many of the routines that produce graphical or statistical output from observation, chemical transport model, and emission model datasets have relied on programming environments that require expertise to configure and adjust (R, IDL, NCL, Matlab, Python, Fortran, SQL, etc). As a result, most observation and model-performance visualization tools have been highly customized to individual scenarios or applications. With recent societal advances in “Big Data” analytics, there are now a host of software packages and libraries that can be used to develop intuitive web-based tools to allow users to more quickly probe environmental data through interactive statistics, time series, bar charts and maps.

Institutions including the EPA, TCEQ, and WESTAR, who are each interested developing their own targeted solutions for web-based data access and visualization, will share their individual experiences and plans for the future. Subsequent discussion may identify potential synergies (to be leveraged in the future) as the needs that are unique to and common among the various teams emerge during the webinar.

Long term, EPA is also interested in identifying metrics and comparisons that the atmospheric modeling community may add to standard model evaluation protocols as the quality and frequency of observations increases and the effort required to analyze data decreases in the future. Although this webinar will not specifically address this topic, if attendees have opinions, they are invited to share as part of the discussion given the breadth of expertise of the speakers and audience.
