Observational, reference and model data on solar EUV, from measurements on AE‐E

Abstract

Information on solar irradiance at wavelengths below 185 nm, observed by the EUVS experiment on the AE‐E satellite over the entire development of the present sunspot cycle 21, is important to many investigations of planetary thermospheres and ionospheres. Strictly observational information is generally lacking in both the completeness and the spectral detail required by the more advanced study programs. Therefore, it has been necessary also to develop computer models in connection with fully detailed compilations of an appropriate reference spectrum. Our selection of appropriate forms of effective publication has been difficult for various reasons. Recognizing that full reproduction of our various lists of observational, reference, and model data in scientific journals would be impracticable, we started a more or less informal procedure of timely release of information to a limited number of particularly interested colleagues. With the present letter, we hope to mitigate at least some of the dissatisfactory aspects of this procedure.
