The problem of diffuse reflection, transmission and emission of infrared radiation by water clouds is investigated in the wavelength region from 5–50 μ. The drop-size distribution of clouds is assumed to be that of altostratus measured by Diem. The phase function and other optical properties of the clouds are estimated from the value of the refractive index of water proposed by Pontier and Dechambenoy. Radiative processes due to both cloud droplets and water vapor in the cloud are taken into account, and a method of averaging the solution over a spectral interval including a number of absorption lines is developed.read more

Estimation of the amount of tropospheric ozone in a cloudy sky by ground-based Fourier-transform infrared emission spectroscopy.
TL;DR: It is shown that the strength of the spectral signature depends not only on the amount of ozone but also on the atmospheric thermal structure, and the detection limit is shown to depend on cloud base height.

Radiative transfer of infrared radiation in model clouds
TL;DR: In this article, the authors evaluated the radiative transfer equation in its scalar form to obtain the emissivity, transmissivity and reflectivity of model clouds at selected infrared wavelengths.

Radiative-diffusive models of the Arctic boundary layer
TL;DR: In this article, the formation of Arctic stratus clouds in the relatively warmer and moister continental air as it flows over the pack ice is considered, where the initial profiles of temperature and relative humidity as well as their values at the surface are specified in advance, and the modification of the continental air is calculated as a time marching problem.

Detection of ground fog in mountainous areas from MODIS (Collection 051) daytime data using a statistical approach
TL;DR: In this article, a new statistical method for the detection of ground fog in mountainous terrain from MODIS Collection 051 data is presented, based on negative correlations between optical thickness and terrain height that can be observed if a relatively plane-parallel is truncated by the terrain.
