Fast Forward Modelling of Cloudy Atmospheric States
Cloud detection always relies on some knowledge of how clear and cloudy observations will differ. In a full Bayesian determination of the probability that an infrared image pixel contains cloud, an estimate of the brightness temperature distribution for clear and cloudy cases is required. A method for estimating this distribution for cloudy atmospheric states through exploitation of the knowled...
متن کاملCondensation: Passenger Not Driver in Atmospheric Thermodynamics
The second law of thermodynamics states that processes yielding work or at least capable of yielding work are thermodynamically spontaneous, and that those costing work are thermodynamically nonspontaneous. Whether a process yields or costs heat is irrelevant. Condensation of water vapor yields work and hence is thermodynamically spontaneous only in a supersaturated atmosphere; in an unsaturate...

متن کاملAn efficient method for computing atmospheric radiances in clear-sky and cloudy conditions
A computationally efficient method is developed to simulate the radiances in a scattering and absorbing atmosphere along an arbitrary path in the spectral region ranging from visible to far-infrared with a spectral resolution of 1 cm. For a given spectral region, the method is based on fitting radiances pre-calculated from the discrete ordinate radiative transfer (DISORT) at several wavenumbers...
