Lunar Brightness Temperature Measurement with CHIME
2021Half a century after measurement of the lunar brightness temperature for preparations of the moon landing, Canadian Hydrogen Intensity Mapping Experiment (CHIME) provides improved instrumentation and a more sophisticated method for the same measurement.

Brightness, Emittance and Temperature
1988During the past fifty years there has been a spectacular growth in the number of applications for particle beams. The various practical requirements scan orders of magnitude in energy, current, and particle mass, from electrons to uranium ions. The behaviour of some of these beams, especially when self-fields are large and interaction with walls or ...

Microwave brightness temperature of snow: Observations and simulations
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016The brightness temperature of snow-covered terrain was monitored from January through April 1985 using tower-based radiometers operating at 1, 16.5, and 37 GHz (vertical and horizontal polarization) in southern Finland. Ground truth data on snow, soil and weather were collected. Layered dielectric, extinction and wetness information on snow at the test

Bright and Semi-Bright Nickel Plating from Low Metal/Low Temperature Solutions
Transactions of the IMF, 1977SummaryThe comparison is made between recently developed low concentration, low temperature bright nickel and semi-bright nickel plating processes and conventional bright nickel and semi-bright nickel processes in respect to the physical properties of the deposits, stress, ductility, levelling etc, and the tolerance of the solutions to impurities ...

Brightness temperature emitted by layered media with nonuniform temperature profile
International Journal of Infrared and Millimeter Waves, 1996Based on the transmission-line theory, this paper describes a new procedure to calculate the radiation from layered media with nonuniform temperature profile. The result is compared with those obtained through the incoherent method and the analysis of the electromagnetic fields.

Colour Temperature and Brightness of Moonlight
Nature, 1923OUR more complete knowledge of full or black-body radiation embodied in Planck's law makes it possible to speak of the temperature of radiation as well as the temperature of radiating bodies. Thus, the temperature of any visible radiation is the temperature to which a black body must be raised to emit light as nearly as possible of the same integral ...

Beam brightness of patchy temperature-limited cathodes
IEEE Transactions on Electron Devices, 1987The beam brightness B of smooth thermionic cathodes is examined in the temperature-limited regime as affected by work-function patchiness. Beam brightness is expressed in terms of the autocorrelation function of the work function nonuniformity in the laminar approximation. The dependence on extraction field strength and other factors is discussed.

Hurricane Imaging Radiometer (HIRAD) brightness temperature validation
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017The Hurricane Imaging Radiometer (HIRAD) is an experimental C-band airborne microwave radiometer developed by NASA Marshall Space Flight Center (MSFC) to provide hurricane's surface wind speed and rain rate. It is intended to expand the current NOAA and US Air Force hurricane surveillance capability by extending the operational Stepped Frequency ...

Low temperature confocal spectroscopy in bright nanodiamonds
2022While colour centres in diamond have numerous exciting room-temperature applications, it remains important to be able to study and control their properties at cryogenic temperatures where crystal phonon activity is suppressed. A cryogenic confocal microscope has been developed using galvanometer beam scanning and a closed-cycle helium cold-finger ...
