Java
VERDI is written in Java 6.0 so it is easy to install and portable across different operating systems.
GUI
The VERDI user environment is an intuitive GUI that makes importing datasets, creating formulas, and generating plots easy.
Supported Plot Types
VERDI currently can be used to create 2-d tile plots, vertical cross sections, scatter plots, line and bar timeseries, contour plots, vector plots, and vector-tile plots,
Scriptable
VERDI can be driven with a scripting language to allow batch-generation of images.

VERDI 1.4 is available for download
- New projection types are supported for the fast tile plot (Mercator, UTM, etc.).
- Grid cell time-aggregate statistics (e.g., per-cell maximum 8-hour average, hours of non-compliance, etc.) feature is available in Fast Tile Plot.
- Batch scripting capability has been added into both the GUI window and the command line.
- Adding multiple observational overlay data sets is now supported.
- Adding vector overlay data is now supported by the fast tile plot.
- Adding and configuring multiple GIS layers are now supported by the fast tile plot.
- New remote file access capability has been added to allow users to run VERDI locally and to access data from remote server.
- Ability to export CMAQ data and the results of VERDI formulas as ESRI Shapefiles (.shp) and ASCII Grid files (.asc).
- Allow alternative numeric scale--logarithmic to the fast tile plot
- All text on fast tile plots is configurable so that the font, size, color, etc can be changed. Users have the option to turn off the display of a particular text item.
- Allow user to specify a time step with a variable in the formula's panel
- Support CSV type observational data
- Remote hosts list is configurable through config.properties file
- Remove file reading utility program and ssh program path are now configurable through config.proerties file
- Temporary folder for reading remote data files is now configurable through config.properties file
- A splash screen is added at the start of the program
- A minor change of the GUI's look and feel happens due to the change of docking frame libraries
VERDI 1.4 Now Available
VERDI 1.4 was made available through the CMAS Center on May 31, 2011. Developed by Argonne National Lab, and further developed by UNC's Institute for the Environment and by Lockheed Corporation through the EPA Modeling and Visualization Laboratory, VERDI provides the CMAQ and SMOKE user community with a new tool for visualizing modeling data. Please direct feedback to cmas@unc.edu.
VERDI Training in Development
The CMAS training staff are hoping to develop a course for VERDI to be offered in the future. Keep an eye on the m3list listserv for an announcement of the course schedule.
