DearDr. Beckman: Weathermodification, although a relatively

ThePanelnowconcludes onthebasis ofstatistical analysis of well-designed

can sometimes lead to less precipitation, andat other times the nuclei
havenoeffect, depending onthe meteorologicalconditions. Recentevidence has

Someexpensive, brute force successes havebeen obtained by burningfuels to

to alter part of the air-surface boundaryor a portion of the free atmosphere.
Black andTarmy(1963) proposedten by ten kilometer asphaltgroundcoatings
to create a "heat mountain"' to enhancerain, orto reducepollution by breaking
throughaninversion. Recently Gray, etal. (1975) havesuggested tappingsolar

modification objectives rangingfromrainenhancementtosnowmelt, cirrus production,
and stormmodification. Thephysical hypotheses have undergonepreliminary
modellingwithpromisingresults, whilethelogisticsappearmarginally
feasible. Drawbacksare the unknownanduncontrollable transport of the dust
anditsenvironmentalunattractiveness.
Acleanerwayof differentially heatingthe air appearsto bea possiblefuture
byproductof the spaceprogram. ASpaceSolarPowerLaboratoryis in theplanning
stages atNASA. Its mainpurposeis to provideelectric power, whichwill
be sent by the space laboratory to the earth's surface. The microwave power
will be convertedtoDCby meansof groupsof rectifying antennas, whichdissipateafractionofthepowerintoheat.
Preliminarycalculations
indicate that
the atmosphericeffect of the estimated heating wouldbe comparableto that by
a suburban area and thus could impact mesoscale processes. Future systems
could dissipatemuchmoreheat andcould conceivably be a cleanwaytomodify
weatherprocesses. Itisnottoosoontobeginnumericalsimulationofatmospheric
modifications that latergeneration systemsofthis typemightbeableto achieve.
Radiation alteration appearsto be a hopeful weathermodification approach
still lacking a developed technology. Acirrus cover has long been welcomedas
naturalfrost protectionwhenit restricts the nocturnalloss oflong-waveradiation.
Morerecently, theeffect of cirrus in cuttingoffshort-wavedaytimeradiationhasbeenmodelledandmeasured.
Artificial simulationofcirruseffects

Alteration of the sea-air interface is also a potentially promising weather
modification technique, particularly to suppressconvection ortomitigatethedestruction

ABLE14—SUMMARYOF THE KANSAS CUMULUSPROJECT (KANCUP) EXPERIMENTS
[From Kostecki: WeatherModification Activitiesin Kansas, 1972-77, 1977]
Project Objectives Assessment1
KANCUP1972, Aug. 5 to
Sept. 30 (cost $95,000,
fiscal year 1973).
KANCUP1973, Aug. lb to
Oct. 5 (cost 558,000, fiscal
year 1974).
KANCUP1974, Apr. 5 to
June8 (cost $54,000, fiscal
year 1974).
Assumingtechnology works, seed for
rain increase; experimentwith both
silver iodide (Agl) and hygroscopic
materials(salt); test groundrelease
of materials; inform general public
aboutprojectandtechnology.
Verify computer modelsof cloud processes;
seedselectively with Agl and
salt; assess useof local pilots and
aircraft; inform general publicabout
projectandtechnology.
Assess minimumoperational requirements;
seed with Agl andsalt using
randomizedcontrols; evaluate characterandfrequencyof
opportunities
in spring compared to summer;
infcrm general public about project
andtechnology.
Opportunitiesdifficult to predict and recognize;
positive, predicted responseto Agl on2 of 16
days(20 percentof seededcells); saltseeding
only occasionally encouraging; moderate
response on only1 of 11 days (10 percentof
seeded cells); ground-based seeding unreliable;
not enough attention given to control
clouds.
Models helpful; seeding frequently produced
predicted response; positive, predicted responseto
Agl on7 of 14 days (42 percentof
seededcells); however, marginal response on
5 of the same7 days; salt seeding on only 2
days; moderate response from 33 percent of
seeded cells; design and instrumentation
inadequate; local pilots need experienced
guidanceto beeffective.
Selective seeding sometimes produced desired
response; positive responseto Agl on8 of 13
days; however, marginal response on6 of the
same8 days; moderate resoonseto salt seeding
on1 of 2 days; springtime cloud systems
usually more organized but seedabilily less
predictable; design and instrumentation
inadequatefor remaininguncertainties)

Defense Departmentaircraft workall weatherpatterns in the mid-Atlantic

flights in a twenty-fourhourperiod. Theseaircraft disperseice nuclei atalmost
infinity concentrations[sic] andinjectit into the atmosphere, starting 24to 48
hours before weatherpatterns moveinto the area. This seeding will dissipate
allsummercumulistorms. In the winter, snowsarechangedinto rain withthe
possibility of someincrease of precipitation. Thisadditional winterrain helps
makethe annual precipitation record look decent. However, rain during the
winter leaches the soil of fertility andseverely erodes cropfields. Snowis so
desperately neededfor a coverto preventthisdamageas well as protectionto

Noindividual hastheright to determinefor himselfwhathis needs are and
produce those needs byartificialmeansto the prejudice anddetriment of his

modification takesmanyforms andproduces, or appearsto produce, desirable
effects. Forexample, thereis fog suppression, lightning suppression, andhail
suppression. In additon, cloud seeding has been used andwill continue to be

Althoughin somerespects the National Oceanographic and Atmospheric Administration
gathers data onall these projects, itdoes notreally function as a
lead agencyor exertsufficient direction, coordinationor control over thecivilian
ormilitaryprojects. Itisclearfromthesecondchart,
furthermore, that considerable
overlapandpossible duplicationexists. Webelieve, however, thatin afield
asdiverseandspeculativeasthis, a greaterdegreeofcentralizationis desirable.
Thissamerecommendationhas beenmadeonanumberof occasions bytheNational
Advisory Committeeon Oceans and Atmosphere:
NACOAfinds that, althoughweappearto stand on the thresholdof practical
weathermodification, and somefacets are operational, in other applications a
sroat dealofcomplexresearchstill needsto be done. Unless thescientificmanpower
andfundingarebetter directed, weassuredlywill continuetomakevery
slow progress towards weathercontrol. NACOAtherefore reiterates its recommendationsoflastyearthat
:
"The manysmall programsin weather modification nowscattered widely
throughthe Federal agencies be focused andcoordinated under NOAA'shead
;
basic cloud physics anddynamicsbe given higherpriority; andthat thelegal,
social, andeconomicimpactofweathermodification be thoroughlyexaminedand
;appropriate regulatory andlicensing legislation be sought." (A Refrort to the
President andthe Congress, NACOA. June29, 1973, pageviii.)
Wealso believeit isparticularly importantthatanysuchcoordination should
bein the handsof a civilian agency; indeed, thatall such research should be
conductedbycivilian agencies.
Considerabledoubthasbeen raisedin the pastoverthe natureofsomeof the
research conducted bytheDefenseDepartmentin theareaofweathermodification.
Youwill recall the not too successful efforts to increase rainfall over the
HoChiMinhTrail several years agoat a cost of $21.G million.
Wehave grave
doubts about the merits ofanyproject such asthis, butweare also concerned
aboutthewayin whichthe incidentwashandled by the Government. Theproject

DearMr. Gude: ThePresidenthasaskedmetorespondtoyourletter

Aconsiderableamountof
careful thoughtandstudy has been devotedto the
subjectofweathermodificationandwhattheFederalroleand,
in particular, the
role ofvariousagenciesshouldbein this area. Asaresult ofthis study, wehavedeveloped
a general strategy for addressing weathermodificationeffortswhich
webelieveprovidesforanappropriatelevelofcoordination.
Forthe mostpart, as yourletter points out, weare just beginningto understand
thepossibilities forweathermodificationandthe complexities that areinvolved.
Inadvertentmodificationofweather andenvironmentthroughindustrial
developmentisindeedaprimeexample.
Therearemanyproblems generated by various weather phenomenasuch as
lossof crops throughhaildamageanddestruction of property caused byhurricanes
andflooding. In manycases the approaches to solving the problems
mayor maynot be best met through weather modification techniques. Other
solutions such as communitypreparedness, better land use planning, andprotectivemeasuresmaymoreeffectivelyandrealistically

Forthis reason, webelieve thattheagencywhichischargedwitha particular
nationalproblemshould be giventhelatitude to seek the bestapproachor solution
to theproblem. Insomeinstancesthismayinvolveaformofweathermodification,
whileinother instancesother approachesmaybemoreappropriate.
While wewouldcertainly agree that somelevel of coordination of weather
modification researchefforts is logical, wedonot believe that a program under
the direction of anyonesingle agency's leadershipis either necessary or desirable.
Wehavefoundfromour studythat the typesofscientific research conducted
byagencies aresubstantially different in approach, techniques, andtypeof
equipmentemployed, depending on the particular weather phenomenabeings
addressed. Forexample, thereis verylittle incommonbetween hurricane suppressionandattemptingto
increase rain or snow. Fogdispersalefforts havealmost
nothingin commonwith any other weathermodification. Each type of
weathermodification requiresadifferentformofprogrammanagementandthere?
arefewcommonthreadswhichrunamongallprograms.

Totlie extent that there arecommonproblems andsolutionsamongthe programs,
the Interagency CommitteeonAtmosphereSciences (ICAS) is bringing
together agency representatives whoare involved in weathermodificationresearch,
for the purposeof sharingtheir ideas andapproachesto various problems.
In addition, aseries of lead agencieshavebeenestablishedto concentrate
efforts in particular areas: Interior in precipitation; Agriculture in lightning
suppression; Commercein severe storms, including hurricanes; NSFin hailresearch:
andTransportationin fog suppression. Theseleadroles provideforcoordination
in areas with commoncharacteristics and have gone a long way
towardeliminating duplicative efforts. Although morethan one agencyis involvedina
generalarea suchasinadvertentmodification, theireffortsarekeyed
towardparticularobjectives.
IhopethisinformationwillbehelpfultoyouandIwouldliketothankyoufor
sharing your views withus. Wewouldbehappyto provide you anyadditional
informationyoumayneedconcerningcurrentefforts intheweathermodification
area.
Sincerely,
NormanE. Ross, Jr.,

Thefuture direction of theDoDweathermodification programis influenced
not onlybyourperceptionsof the usefulnessof the technology, butalsobythe
EnvironmentalModification Convention. TheEnvironmentalModification Convention
constrains the useof military weathermodification activities to those
not havingwidespread, long-lasting, or severeeffects. Theeffect of theEnvironmentalModification
Convention, whensuperimposed on ourpresent perceptions
of technology, is to further devalue the developmentof weathermodification
as a weaponof war. Asaresult, ourpresentefforts are directed solely at fog
andclouddissipation.

StateStatutesConcerningWeatherModification
Twenty-nine States were found which have sometype of statute discussing
weathermodification. Thesestate statuteswerefoundbyanexaminationof the
indices to thestate codesunderthetopicsweathermodification, climatecontrol
andcloudseeding. Statuteswhichhavebeenrepealedarenotincluded.
1
Thefollowing chart divides the types of weathermodification statutes into
three maincategories: comprehensive, licensing andother. Thecomprehensive
categorywouldinclude those statuteswhichincludeprovisionsrelatingnotonly
to licensing but also to generalpolicy, liability, etc. State statutes putin the
licensing category areentirely, or almostentirely, concerned with thelicensing
of weathermodifiers. The"other" category wouldinclude States like Hawaii
whichdiscuss weathermodification in some mannerbut have neither a comprehensive
statute norone concerninglicensing. States forwhichnoprovisions
concerningweathermodificationwerefoundcontainanotationof"noprovisions"
onthe chart. Theexacttext of those provisions follows thechart.
It should be noted thatin mostcases the State codes werecurrent through
the 1976sessions, however, in somecases the mostcurrent material available
wasfromthe1975sessions.
