Stand-off Thermal IR Minefield Survey: System concept and experimental results
TL;DR: The CLEARFAST system for thermal IR stand-off minefield survey is described in this paper, which allows a diurnal observation of hazardous area, detecting anomalies, locating and searching for targets which are thermally and spectrally distinct from their surroundings, and estimating the physical parameters, i.e. depth and thermal diffusivity, of the detected anomalies, and providing panoramic images indicating the locations of suspect objects and known markers.

Introduction of clouds in dart model
TL;DR: In this article, clouds were characterized with user specified optical properties and vertical distribution, and they were modelled as layered one-dimensional medium that coexists with gases and aerosols.

Calculation of surface spectral irradiance using the Geant4 Monte Carlo toolkit
TL;DR: In this article , the spectral direct normal irradiance (DNI) of the surface spectral irradiance, with a spectral resolution of 1 nm in the range of 280-1600 nm, and 5 nm in range of 1600-3000 nm, has been calculated with the Geant4 Monte Carlo simulation toolkit using the US Standard Atmosphere 1976 model and the reference extraterrestrial solar spectrum SOLAR-ISS.

Opto-Mechanical Assembly and Analysis of Imaging Spectrometer
TL;DR: In this paper, an off-axis three-reverse imaging system was adopted, and a single aspherical mirror system was selected through MTF test comparison analysis, and the spectral test results showed that the spectral resolution of the imaging spectrometer is less than 7 nm.

Spectrally Resolved Flux Derived from Collocated AIRS and CERES Observations and its Application in Model Validation
TL;DR: In this paper, a multivariate linear prediction scheme is used to estimate spectral fluxes at frequencies not covered by the collocated Atmospheric Infrared Sounder (AIRS) and the Clouds & the Earth's Radiant Energy System (CERES) measurements over the tropical oceans.

Numerically stable algorithm for discrete-ordinate-method radiative transfer in multiple scattering and emitting layered media.
TL;DR: An advanced, thoroughly documented, and quite general purpose discrete ordinate algorithm for time-independent transfer calculations in vertically inhomogeneous, nonisothermal, plane-parallel media for Atmospheric applications ranging from the UV to the radar region of the electromagnetic spectrum is summarized.

TL;DR: The HITRAN molecular absorption database as mentioned in this paper contains line parameters for 31 species and their isotopomers that are significant for terrestrial atmospheric studies, including chlorofluorocarbons and other molecular species that are not amenable to line-by-line representation.

A description of the correlated k distribution method for modeling nongray gaseous absorption, thermal emission, and multiple scattering in vertically inhomogeneous atmospheres
Andrew A. Lacis,Valdar Oinas +1 more
TL;DR: A radiative transfer method for treating nongray gaseous absorption and thermal emission in vertically inhomogeneous multiple scattering atmospheres is described in this paper, where probability density distributions of absorption coefficient strength are derived from line-by-line calculations to construct line-By-line and band model based k distributions.
