Houston High Ozone
September 1, 2006
Hourly Data Graphs

Images Description

The graphs above show time series trends during the day of hourly ozone, oxides of nitrogen (NOx), and highly reactive volatile organic compounds (HRVOC) for all sites in the Houston area by compound and for selected compounds at all sites that have O3, NOx, and HRVOC. The scale on each graph may vary (to provide more detail) - so be sure to check the scale when comparing measurements from one graph to another. The data presented in these graphs has not been fully validated and may be subject to change.

The workbook file above provides more detailed information in XLS format, including all of the graphs and data for this event. The graphs are in separate worksheets (see tabs at bottom of file window). When viewing these graphs, running the cursor over a line in the graph will display the name of the site and the hourly concentration at each point on each line.
