Summary
Abstract: The Air Quality Atlas is a collection of maps prepared by the Air Quality
Analysis Section in the Region 6 office of the U.S. Environmental Protection
Agency (EPA). The atlas presents a spatial analysis of air quality in EPA
Region 6 for 1996, focusing on the six criteria pollutants for which the EPA
has set primary and secondary standards to protect public health and welfare.

Quality Quality control for binary and ASCII data output files takes place as follows. Binary-data: Start time, sample time, time to water and time marks are controlled with rawuls.exe. Days with missing time marks are left out and binary data are converted to ASCII data with sepuls.c. ASCII-data: Start and end time of lowdraftdata (the data acquired at 5 minute intervals) are controlled. Start and end time of highdraftdata (the data acquired at 10 second intervals for 25 minutes at 0000 and 1200 UTC) are controlled. Temperature and pressure data are plotted.
Access Constraints None.
Use Constraints None.
