A survey conducted several years ago within the local atmospheric science community had indicated the need for a comprehensive reference book of atmospheric chemistry and physics. The present compilation of data has been prepared in an attempt to fi ll this need. While the subject, as a whole or in parts, has received an adequate treatment in textbooks, encyclopedias, and in other overviews, these publications do not generally present numerical data but discuss important observations by way of illustrations. Even the current scientifi c literature tends to display observations and results graphically and often relegates numerical data, on which the results are based, to unpublished supplements made available only.
