Resumo

This chapter discusses contribution of Alexander Dalgarno to aeronomy. In a career extending over 35 years, Dalgarno has authored or coauthored almost 500 papers, an average of more than 14 per year. Approximately 70 of his papers are devoted specifically to aeronomical topics. He wrote two papers in 1953 and 1954, both with David Bates. One concerned the altitude of the layers responsible for the airglow. The second anticipated what was to become a major theme of his research in the 1960s and 1970s, the nature of the dayglow. He traveled widely and was exceptionally well informed on what was being measured and what could be measured. He was aware also of measurements indicating that the electron temperature in the ionosphere was elevated relative to the temperature of the neutral gas. Cross sections for photoionization of atomic oxygen, identifying the nature of the ionic products, were evaluated and published in 1964.
