<br />of Weather Modification, 19:1-12.
<br />
<br />Three hundred million dollars in federal funds have been expended since 1960 to conduct research and
<br />to develop weather modification capabilities. This has resulted in techniques to operationally eliminate
<br />fogs, to reduce or enhance stratus clouds, and to increase snowfall and rainfall during certain conditions.
<br />But, the annual n$earch and development funding has been halved since 1978, and the general public,
<br />many scientists, and most government decision makers now believe, rightly or wrongly, that major
<br />scientific uncertainties and policy problems exist in the field. Rather than serving as spurs to heightened
<br />federal efforts, these beliefs have had a dampening em:ct. Support for the field is decreasing and
<br />weather modification research and development is in trouble.

<br />18:1-7.
<br />
<br />Evaluation of outcomes of weather modification has been a necessity and an evolving process. Early
<br />efforts were largely based on statistical techniques of smface weather variables, but over the past
<br />20 years, use of physical processes assessment has grown. Great progress has been made in learning
<br />how to effectively use physical and statistical approaches for the assessment of weather modification,
<br />both operational and experimental efforts.
