The St. Louis Regional Air Pollution Study (RAPS), provided a comprehensive documentation of regional air quality, meteorology and pollutant emissions. RAPS involved an average data collection rate in excess of one million observations per day over a 3 year period (1974-1977). The overall objective of the Regional Air Pollution Study (RAPS) was to create a comprehensive research data set to be used in the development, evaluation and validation of Air Quality Simulation Models. The RAPS 1976 hourly area source emissions data are contained on a series of six IBM binary or eighteen CDC binary tapes. Hourly emissions of the criteria pollutants (1) total suspended particulate, (2) sulfur dioxide, (3) nitrogen oxide, (4) total hydrocarbons (5) carbon monoxide, as well as fugitive dust and the breakdown of total hydrocarbon into moles of nonreactive hydrocarbon, paraffins, olefins, aromatics and aldehydes are reported for 1989 RAPS grids varying in size from 1 square kilometer to 100 square kilometers. The gridded area covers Air Quality Control Region (AQCR) 70 in entirety. The reported hourly data combines several major categories of area source emissions: river vessels, fugitive dust, highways, railroads, stationary residential and commercial, off-highway mobile, stationary industrial sources and airports. The stationary industrial source category contains the minor point sources emitting less than 0.01% of a given pollutant. The complimentary hourly point source data is available on another series of tapes. State-of-the-art emission inventory methodologies in 1976 were used to provide much of the temporal and spatial resolution required for use in Air Quality Simulation Models. The first file on each tape contains file formats and record layouts. The second file on each tape contains grid descriptions; thus each tape may be accessed independently. This tape covers the time period of January 1-21, 1976. Publications: Regional Air Pollution Study (RAPS) Emission
