Impact/Purpose:
The Visualization Environment for Rich Data Interpretation (VERDI) is a critical tool used air quality modelers to visualize and analyze data to support model development, evaluation and application. VERDI is an interactive Graphical User Interface (GUI) written in Java that also supports command line operation and batch scripting to create visualizations. Users can create a wide range of plot types including spatial, time series, scatter, cross-section and areal interpolation from a variety of sources such as the Community Multiscale Air Quality (CMAQ) modeling system, the Weather Research and Forecasting (WRF) model, and EPA's Advanced Air Quality Modeling System (AAQMS) that is under development.
Description:
Output 7.4 will deliver an advanced next generation air quality model (NGAQM) supporting multiscale air quality assessment over a global domain on icosahedral-type variable meshes. The Visualization Environment for Rich Data Interpretation (VERDI) is a Java-based visualization tool used to examine, analyze, and plot regional air quality and meteorological (model results on rectangular grids. Development is underway to extend VERDI to read and analyze data from the new NGAQM global domain, making VERDI the only interactive plotting tool to support icosahedral meshes. Many features remain to be implemented in VERDI to support the ongoing NGAQM development. Modifying VERDI for use in a cloud environment will enable it to interact with large online modeling data. The VERDI product will facilitate model development and evaluation for the broad air quality modeling community including EPA, state and local agencies, academic institutions, and the private sector. Assumptions/Constraints: Product development is dependent on project funding for the High-End Scientific Computing Environmental Modeling and Visualization Laboratory (HESC/EMVL) and their contractors.
