I don't recall what year, could have been in the mid 1970s, and exactly how I got involved in emission from smoke stack but here was another subject that involved a great deal of mathematics. The question was, "What is the distribution of emissions from generating plants?". This was of concern to Columbia as they had a great deal of compressor stations that emitted pollutant, such as NO₂, nitrous dioxide. The math involved dispersion theory.

The government was going to regulate the emissions of NO₂ and, thus, Columbia had to know what they were and where they went as the emission was based on ground level values. Once again, the government has a program to determine the ground level values and I worked on my own program (why I am not sure) to predict the emission levels around source, our compressor station.

Basically, the ground level emission values are based on (a) wind direction (b) wind speed (c) source height, i.e. smoke stack height, and (d) amount of emission being produced. Again, the model was all math and physics so I had no trouble in producing a model that duplicate current models by the government and private sources, i.e. other gas companies, generating plants, etc.

Since my program was easily available to Columbia, anyone could use it to predict ground level values from any source. Today I can't remember how the program was used but I do know it was an interesting project and really fun to work on.

I am not sure but I believe it was about this time that Jeanne and I got married. I had been divorced from Mary Ann for over a year and met Jeanne through her Christian Date Club which she ran out of her house in Bexley in the evening after coming home from her job as a secretary.
