A series of 10-mb charts analyzed 3-times monthly for the first
year of the IGY 1s nearing completion.
To make analysis of the 10-mb
charts possible, special procedures, including extrapolation of data,
plotting of auxiliary data, application of solar radiation correction:
and methods of analysis, were developed.
Solar elevation charts and
complete listing of radiosonde types used at United States and Canadis
stations during the IGY period were prepared by months and by obdservat
time to aid in determining solar radiation corrections to temperature <
height.
Logistic and Network Design Support.
Administrative support and suppl
assistance was provided for the maintenance of the AEC gummed-film and
ion-exchange networks and for the AEC-NRL 80th meridian sampling netwc
Arrangements were made for Weather Bureau stations to make ion-exchang
collections.
The Weather Bureau-AEC carbon-14 program for world-wide
air and sea water sampling at ocean locations was inaugurated.
Arrang
ments were made to make quarterly collections aboard Coast Guard Weath
Patrols, Ice Patrols, supply ships to arctic and antarctic bases and
aboard U. S. merchant vessles in the Pacific, South Atlantic and India
Oceans.
Evaluation and interpretation.
An evaluation of the AEC ground-level
sampling program was made and a report submitted.
Many research contr
and proposals relating to the meteorological aspects of fallout were
reviewed and recommendations made.
Significant contributions were made to the work of the NAS Commit
on the Biological Effects of Atomic Radiation.
