Effective with this issue,Radio Sciencewill be published under the sole editorial control of the U. S. National Committee of the International Union of Radio Science (URSI). As most of you know, it has been published since 1964 by the Department of Commerce with the cosponsorship of USNC/URSI. The new publisher is the American Geophysical Union (AGU), which currently publishes several leading journals in the geophysical sciences. The interests of AGU and USNC/URSI are complementary; because the Council of the AGU serves as the U. S. National Committee of the International Union of Geodesy and Geophysics (IUGG), an international complementarity of interests also exists.
