gating the efTects of the following weather hazards: hurricanes, hail 

 storms, fog, and lightning. 

 • Establishment of a coordinated national and international system for 

 investigating the inadverent efTects of manmade pollutants, with a 

 target date of 1980 for the detennination of the extent, trend, and 

 magnitude of the efTect of various crucial pollutants on local weather 

 conditions and on the climate of the world. (NACOA wishes to point 

 out that a relatively new candidate as a major pollutant for inclusion 

 in the third goal is waste heat. Projected trends indicate this could 

 be an observable factor in the general circulation of the atmosphere 

 by the year 2000.) 

 NACOA supports these goals and believes that specific sets of research 

 projects can and should be defined to insure their accomplishment. 



We believe that NOAA should take the lead in developing and co- 

 ordinating the implementation of such a program. Although the track 

 record of the Interdepartmental Committee of xAtmospheric Sciences 

 (ICAS) is generally excellent, and ICAS should prove of value in this 

 program as well, the dispersive forces serving to fragment the program 

 are strong. We feel that a formal lead agency assignment is desirable and 

 that NOAA is the appropriate candidate. 



We believe also that the details of this program sliould be guided by 

 a series of "requirement" analyses and that the appropriate mission agen- 

 cies, such as Interior, Agriculture, etc., have a vital role to play. 



Finally, as capabilities approach the stage of operational readiness, a 

 systematic assessment should be required for approval of candidate opera- 

 tions. We suggest that mission agencies develop the capability to generate 

 plans which provide cost and schedule estimates for the acquisition, im- 

 plementation, and operation of weather modification systems. These plans 

 should : 



• show that the technology needed is sufficiently in hand — that pri- 

 marily engineering rather than experimental effort is required; 



• show that the mission and performance envelopes are defined; 



• show that the best technical approaches are planned for utilization ; 



• show that trade-off analyses have been made to demonstrate that 

 the proposed operational program is cost-effective in comparison 

 with other techniques that could be used to satisfy the need ; 



• show that cost and schedule estimates are credible and acceptable; 

 and 



• show that legal, social, economic, and environmental impacts have 

 been assessed. 



Operational weather modification programs which can be depended 

 upon to be effective in mitigating the effects of large-scale weather gen- 

 erated disasters are not in hand. Major technological problems still remain.
