Project @.2-- Basic Thermal Radiation Measurements - W. B, Plum
OBJECTIVE
The objective of this project was to measure the time history of
irradiance, thermal radiant energy, and the spectral distribution of
thermal radiant energy from three stations with a time resolution of
20 msec; the irradiance and spectral distribution of irradiance from
two stations with a time resolution of 50 microseconds,
From these
data it was expected to get a general transmission coefficient for
the atmosphere, the transmission coefficients for the atmosphere for
narrow wavelength bands, scattering coefficients as a function of the
field of view, and the partition of
energy between the first and
4
second thermal pulses,
INSTRUMENTATION
Three stations were instrumented for this shot.
Station 810.01 on
Yurochi (DOG), 34,940 feet from GZ; Station 811.01 on Aomoen (GEORGE),
48,979 feet from GZ; and Station 811.02 on Bikini (HOW), 92,628 feet
from GZ.
NRDL radiometers and calorimeters, listed below were used at
each station.
Two recorders were used at each station.
Duplicate in-
struments consisting of 11 calorimeters and one radiometer were connected to each Heiland oscillographic recorder.
