The report contains all of the data collected in the Los Angeles Basin during the period August 22 to November 14, 1968 as discussed in Volume I. The data has been reduced to meaningful units and presented in tabular form in four sections. Chemical concentration data include those for carbon monoxide, total hydrocarbons, individual C1 to C10 hydrocarbons, oxidant, ozone, nitric oxide, nitrogen dioxide, formaldehyde, acrolein and total aliphatic aldehydes. Meteorological parameters recorded are temperature, relative humidity, wind speed and direction, and ultraviolet radiation intensity. Total hydrocarbon concentrations greater than 8 ppm carbon are subject to error because of electronic damping of the instrument signal. All of the other categories of data have been examined and are believed to be valid, although occasional erratic points must be anticipated in any such massive volume of data. (Author)
