To detect RIFA nests, the spectral reflectances of 4 kinds of soil samples, namely, RIFA nest soil, ordinary soil surrounding RIFA mounds, nearby grass, and bare sand in the same environment were compared using spectral technology.
Given a surface reflectance p and direct illuminance ED due to the luminaires, it is:
i] is the ith measurement of spectral reflectance, and n is the number of measurements.
Reflectance measurements show that insect screens generally have a negligible specular component; hence, the beam-beam (specular) reflectance, [[rho].
Spectral reflectance data for non aged and aged filter papers soaked in surface active agent (SAA) solution are presented at Fig.
The integrated absorptivities are lower for the high temperature emitters because their emissions are mostly in the near infrared region where the spectral reflectances of the coatings are higher.
The work reported here was part of an effort arising from a competency project entitled "Measurement Science for Optical Reflectance and Scattering" involving four laboratories at NIST: the Building and Fire Research Laboratory, the Information Technology Laboratory, the Manufacturing Engineering Laboratory, and the Physics Laboratory.
The internal reflectances of the free standing film, as appearing in Eqs 14 and 15, can be represented by the internal reflectances of the first and the second internal reflections.
Aerosols are typically studied over water, due to the relatively constant reflectance of water and the ability to easily separate surface and atmospheric contributions on the satellite signal.
