Jovian Clouds and Haze
At wavelengths from the near-ultraviolet (0.2 μm) to the infrared (5 μm) Jupiter’s appearance is dominated by contrasts produced by clouds and haze. It is important to understand the distribution and optical and physical properties of cloud and haze particles because they play a major role in the radiative heat budget, and they can tell us about atmospheric processes such as stratospheric circu...
متن کاملHaze, clouds and limited sky visibility: polarotactic orientation of crickets under difficult stimulus conditions.
Field crickets (Gryllus campestris L.) are able to detect the orientation of the electric vector (e-vector) of linearly polarized light. They presumably use this sense to exploit the celestial polarization pattern for course control or navigation. Polarization vision in crickets can be tested by eliciting a spontaneous polarotactic response. Previously, wide and 100% polarized stimuli were empl...
متن کاملEffects of Arctic Haze on Clouds and the Surface Radiation Balance
In the Arctic, concentrations of aerosols accumulate in winter and spring, reaching a maximum in April, dissipating by summer. It has long been recognized that high springtime aerosol concentrations, dubbed “Arctic Haze”, are due to anthropogenic activities. More recently it has been suggested that Arctic Haze might alter the surface radiation balance by increasing cloud albedo (Twomey, 1991) a...
متن کاملReformulating atmospheric aerosol thermodynamics and hygroscopic growth into fog, haze and clouds
Modeling atmospheric aerosol and cloud microphysics is rather complex, even if chemical and thermodynamical equilibrium is assumed. We show, however, that the thermodynamics can be considerably simplified by reformulating equilibrium to consistently include water, and transform laboratory-based concepts to atmospheric conditions. We generalize the thermodynamic principles that explain hydration...
متن کاملHaze and Cirrus Removal for Remote Sensing Image by Haze Thickness Map Estimation
Multispectral satellite images are often affected by haze and/or cirrus. A previous paper conferred a haze removal method that calculates a haze thickness based on a local search of dark objects. The haze-free signal is restored by subtracting the HTM from the affected image. The HTM method is substantially improved by employing the 1.38-μm cirrus band. The top-of-troposphere reflectance cirrus...
