TL;DR: In this article, a five-year aircraft experiment to verify the quality of satellite cloud winds over oceans using in situ aircraft inertial navigation system wind measurements is presented, and the final results show that satellite measured cumulus cloud motions are very good estimators of the cloud base wind for trade wind and subtropical high regions.
Abstract: A five year aircraft experiment to verify the quality of satellite cloud winds over oceans using in situ aircraft inertial navigation system wind measurements is presented. The final results show that satellite measured cumulus cloud motions are very good estimators of the cloud base wind for trade wind and subtropical high regions. The average magnitude of the vector differences between the cloud motion and the cloud base wind is given. For cumulus clouds near frontal regions, the cloud motion agreed best with the mean cloud layer wind. For a very limited sample, cirrus cloud motions also most closely followed the mean wind in the cloud layer.

TL;DR: In this article, a numerical cloud model is presented which can describe the evolution of a cloud starting from moist aerosol-laden air through the diffusional growth regime, which is designed for the direct support of cloud chamber laboratory experimentation, i.e., experiment preparation, real-time control and data analysis.
Abstract: A numerical cloud model is presented which can describe the evolution of a cloud starting from moist aerosol-laden air through the diffusional growth regime. The model is designed for the direct support of cloud chamber laboratory experimentation, i.e., experiment preparation, real-time control and data analysis. In the model the thermodynamics is uncoupled from the droplet growth processes. Analytic solutions for the cloud droplet growth equations are developed which can be applied in most laboratory situations. The model is applied to a variety of representative experiments.

TL;DR: In this paper, a one-dimensional cloud model with a variable radius has been developed, which is capable of being tuned to give internal cloud properties (such as liquid water content) that are in reasonable agreement with field observations.
Abstract: A one-dimensional cloud model with a variable radius has been developed. The model is capable of being tuned to give internal cloud properties (such as liquid water content) that are in reasonable agreement with field observations. Unlike many other one-dimensional cloud models, the cloud base rises only slowly over the lifetime of the cloud. The model is compared with two other types of one-dimensional model: a steady-state model and an Eulerian time-dependent model.

TL;DR: In this article, the authors discuss the methodology and accuracy of extracting multilevel cloud motion measurements from stereo digital imagery acquired from geostationary orbit and discuss the accuracy of computing the relative altitude of the wind vectors.
Abstract: It has been demonstrated that geostationary satellite imagery provides an effective means of extracting two-dimensional cloud motion wind measurements over large areas. The addition of cloud height information is necessary, however, for the proper assignment of altitude to the wind vectors. This paper discusses the methodology and accuracy of extracting multilevel cloud motion measurements from stereo digital imagery acquired from geostationary orbit.
