We have expanded on previous methods for correcting sense, the requirement of thermodynamic equilibrium in thermal infrared field measurements for atmospheric Kirchhoff ’s law is violated (Badenas, 1997). downwelling radiance (Salisbury and D’Aria, 1992; Korb Nerry et al. (1990a,b) and Labed and Stoll (1991) et al., 1996; Hook and Kahle, 1996) by comparing the used the ‘‘emissivity box’’ approa...
Introduction: Thermal infrared (TIR) emissivity spectral measurements of planetary surfaces have diagnostic features indicative of rock and mineral compositions. These include: (1) the Christiansen feature (CF), an emissivity maximum resulting from a rapid change in the refractive index at wavelengths just short of the fundamental molecular vibration bands, (2) the reststrahlen bands (RB), the ...
Foam on the ocean surface significantly increases the brightness temperatures measured by microwave radiometers. Previous results have shown that the microwave emissivity of foam on a calm water surface is significantly less than one and depends upon polarization and incidence angle. Recent radiometric and video observations of large-scale breaking waves from the R/P FLIP during the FAIRS exper...
The multiband MBP 98A pyrometer developed for non-contact temperature measurement of objects with unknown and wavelength-dependent emissivity has been presented in this paper. The pyrometer was designed using single thermoelectrically cooled PbS detector of spectral band of 1-2.5 Ilm and 8 narrow-band optical filters. It enables temperature measurement of objects at temperature within a range o...
This paper describes the concept of the hyperspectral Earth-observing thermal infrared (TIR) satellite mission HiTeSEM (High-resolution Temperature and Spectral Emissivity Mapping). The scientific goal is to measure specific key variables from the biosphere, hydrosphere, pedosphere, and geosphere related to two global problems of significant societal relevance: food security and human health. T...
We show that the direct Urca process of neutrino emission is allowed in two possible phases of nonspherical nuclei (inverse cylinders and inverse spheres) in the mantle of a neutron star near the crust-core interface. The process is open because neutrons and protons move in a periodic potential created by inhomogeneous nuclear structures. In this way the nucleons acquire large quasimomenta need...
Transition probabilities governing the interaction of energy packets and matter are derived that allow Monte Carlo NLTE transfer codes to be constructed without simplifying the treatment of line formation. These probabilities are such that the Monte Carlo calculation asymptotically recovers the local emissivity of a gas in statistical and radiative equilibrium. Numerical experiments with one-po...
