Integrating National Climatic Data Center (NCDC) archived datasets for air quality investigations

The integration of datasets archived at NCDC useful for air quality investigations is described. Land-Surface Observations and Upper Air observations including visibility, temperature, wind direction and speed data from airports, rawinsond and cooperative observing stations are used in urban climatologies, and have applications in transport models and public health. Example studies are presented of seasonal trend analysis in visibility, air stagnation studies, air source vs. visibility studies, and temperature ozone correlations.
