Slopes and intercepts are calculated for the multi-point calibrations and are applied to subsequent data collected. Failed calibrations or span checks will result in automatic data rejection. The regional office workstations call each of the monitoring sites located in their regions every fifteen minutes. It takes approximately five to seven minutes for the data to be collected and sent upstream to Austin. Thus, data from across the state is available about twenty to twenty-five minutes after it is measured.
Products range from tabular reports to ozone concentration animation loops.
There are many interfaces available for pollution product generation. A Manual Validation interface also graphically displays pollution and meteorological data, and allows validators to set or change data flagging codes and to recover data that has been automatically rejected. There are literally hundreds of web pages available for viewing data. The web pages can be used to monitor overall system performance and health as well as viewing collected data. Web pages are being developed continuously as new ways of looking at data are conceived.
