This visualization shows simulations of ozone concentrations in eastern Texas. Emissions in Houston cause ozone concentrations to rise in other parts of the state, particularly in central and north Texas; thus, it is apparent that emissions from one city can affect ozone levels in an entire region. These simulations use various sources of data including satellite observations and land-based measurements.
TACC staff developed a custom OpenGL application to visualize the data sets. This application combines geospatial data with the simulations to produce time-series animations of the ozone concentration across Texas. Cutting planes and isosurfaces show the ozone concentration in units of parts-per-billion.
