Abstract Title: NUMERICAL SIMULATION OF CLOUD MICROSTRUCTURE EFFECT ON SATELLITE SIGNAL AND APPLICATIONS
Abstract: The urban climate is frequently complicated by special orographic features such as lakes. It is then
not always possible to isolate urban from other contributing factors. For these reasons there is increasing interest in special micro-meteorological studies of a city, although a complete energy balance estimate had
yet to be attempted. There is a very real need for a detailed description of the heat, water vapor and pollution source strengths and emission heights throughout the urban area. Only then will it be possible to
arrive at some reasonable estimate of the energy budget of a city.
This paper presents results of consecutive numerical simulation of the satellite signal (SS, cloud reflectance) for frontal model stratiform clouds.The simulation is based on the next models:
a) The time-dependent 1D numerical model of winter mixed frontal stratiform clouds with detailed microphysics and several forms of ice crystals.
b)Models of computation of light scattering by drop and crystal systems in clouds.
Simulations of scattering characteristics of liquid drops are based on the Mie theory (Deirmendjian ,1969).
Simulations of scattering properties for randomly oriented ice crystals are based on the geometric optics and the far-field diffraction
