Sources of Cloud Nuclei and Development of Remote Sensing Techniques for Cloud Parameters

Abstract

Development of remote sensing methods for determining cloud and fog parameters, using passive techniques. Development and improvement of mathematical inversion procedures for remote sensing. Field and laboratory measurements of cloud nuclei. Theoretical modelling (by radiative transfer theory) of cloud layers and discrete clouds under solar illumination in the visible and near-infrared; identification therefrom of spectral features and/or differences which would enable differentiation (without direct insitu sampling) of (for example) ice clouds from water clouds, large drops from small drops, etc. Development and field utilization on a modest scale of experimental systems to verify (or disprove) these concepts suggested by the theoretical modelling. Development of relevant numerical techniques for forward and inverse problems.
