Project 5.7 - Thermal Flux and Albedo Measurements fror Aircraft tt, P. F. Harwerd
OBJFCTIVE
The objectiwa of this shot was to obtain thervmal flux and albedo
informtion of a nuclear detonation with airborne calorimeters, radio-~
meters, afri sixteen millimeter motion picture cameras,
INSTRORTATION
Instrumentation within *he purwlew of Project 5.7 which was ine
stallei in the 3-57 incluie! nineteen NRDL calorimeters and two VROL
raiiometers for measuring the direct and surface reflected thermal
radiation.
These instruments possessed various fielis of view and
were suitably ‘iltare? to ottatn qualitative spectral
information,
vraphic
tstribition
Six SSAP "~% cameras were utilized *o obtain photo-
overage of the fireball, the earth's surface, and of clouds
beneath tre aivcraft,
Two :f the cameras oriented tawarde ground sero
were equipped with spectrosecoic attachrents to obtain continucus
spectra in the wisible rerio.
Of the cther Swe tail position caneras,
one caters had e blue filter ini the othe- Ned a ret filter for the
purpose sf obtafning pictures at both extremes of the visibie region
of the spectrum,
The’ remaining two cagevas were oriente! wertica ly
for the mrpose of obtaining chotographic coverage of the earth's
surface ani of clouis beneath the eaircrefs,
Instrumentation installe: dn the 44 conaststed of the basic
twenty-one thermal instruments, and twelve cameras.
