CONGRESS OF THE UNITED STATES Joint Committee on Atomic Energy February 4.195427 Brig. Gen. K. E. Fields, USA Division of Military Application -U. S. Atomic Energy Commission 1901 Constitution Avenue ae Washington 25, D. C. ~ Dear General Fields: The Committee 1s interested in knowing whether or not there” were any unusual weather pheonmena which developed immediately. following the IVY test shots. To this end I wrote you on” :.” November 14 requesting a copy of the report entitled "Weather o Conditions Following Operation IVY", which, according to informa ~tion given the Committee, discusses this question. Your reply of Nevember 20 referred us to the Task Force. ** Commander, For reasons of his own the Task Force Commander has ~. informally stated that he feels it is impossible to furnish this.’ * information to the Committee. Since the Task Force Commander =. was acting as an agent for the Commission in the conduct of these tests, I should like to request that your office obtain... the requested report for the Joint Committee. I understand in- |. formally that the report is rather controversial and that a.sub-. stantial body of opinion considers it to be strongly biased.‘ — It would therefore be helpful to have responsible meteorologists. and other scientists who were present at the test comment on ° this matter to the end that the Committee may have the benefit. of &@ well rounded discussion of this matter by your office. Graves comments would be particularly helpful. Dr. ° In summary the Committee desires to have the AEC furnish > a copy of the Pate report and any other information bearing on unusual weather phenomena following the IVY test that the AEC™ has. Sincerely yours, /3/ Corbin Allardice .
