VOLUME 7 Number 2 December 1975

EDITOR’S NOTE Volume 7, Number 2, is a special edition of THE JOURNAL OF WEATHER MODIFICATION. The publication arose from the high interest in the program developed for the Fall Meeting held in Calgary, Canada, 4-5 September 1975. Formal papers and comments presented at that meeting were considered by the membership to be of sufficient importance for assembling in a single volume of JWM. The Publication Committee appreciates that response from those who presented information at that meeting and organized their presentations for publication. For purposes of this volume, the various presentations are reprinted exactly as the authors submitted their material. TABLE OF CONTENTS
