Atmospheric EUV Absorption Data for February 1974

Description

These EUV atmospheric absorption data are on a magnetic tape created by the principal investigator on a Xerox Sigma 9 computer. The data are for one month only (February 1974). Each record in each file is a printable line of no more than 128 characters. Absorption data at wavelengths of 175 A, 584 A, and 1609 A, are given for three regions -- daylight, sunrise, and sunset. The data include the reference height, optical depth, integral columnar particle density, longtitude, latitude, magnetic dipole latitude, local solar time of the reference point used, Greenwich mean time, solar zenith angle, and parameters defining statistically the fit of the data curves.
