O3RDME84.INF 4/1/93 The 12 files of data containing high resolution cross sections of ozone at 195 K are arranged in files with points in ascending order of wavenumber. The file O330KWN.XSC contains the cross sections of all points measured between 30000 and 31000 cm-1. The points are not evenly spaced in wavenumber, or wavelength. This data was originally published in 1984, (Planetary Space Science, 32(2): 239-248) with a discussion of the assumptions on which the relative cross sections were put on an absolute basis. Later, in 1988, absolute cross section measurements were made with which the original data was renormalized (Planetary Space Science, 36(4): 395-398). The cross section files here reflect these most recent absolute measurements. The files sent only go down to 253.75 nm since the cross section measurements of the region with wavenumber lower than that has been superseded by new measurements in the region 185-254 nm to be published shortly in the Journal of Geophysical Research. This new data is at significantly lower resolution than the earlier data. The files consist of one initial title/label line; a second line labelling the two columns of the data; and then a number of lines of data, each line corresponding to a measured point, and consisting of first the value of the wavenumber position, and second the value of the cross section/molecule (sigma) of ozone at that position. A FORTRAN format statement for reading the data lines could be: FORMAT(1x,F10.3,3x,E11.3) There are three additional information files included: this one; a file containing the publication information of the articles in which this data was presented (including title, authors and address, journal reference, and the abstracts); and a third information file containing the title lines of all of the data files.
