Theoretical considerations for describing the state of the sky through automatic techniques: final report

This report describes a computer model for the simulation of optical and radar ceilometers. The model has two components, a statistical cloud model that describes a sky composed of multiple layers of random clouds, and an instrument model that permits the calculation of the responses of ceilometers. The digital computer program based on this model is described, and program flowcharts, listings, and sample printout are given.

本报告介绍了一款用于模拟光学云高仪与雷达云高仪（ceilometer）的计算机模型。该模型包含两个组成部分：其一为统计云模型，用于描述由多层随机云团构成的天空环境；其二为仪器模型，可用于计算云高仪的响应特性。本文还介绍了基于该模型开发的数字计算机程序，并附带给出了程序流程图、代码清单以及示例打印输出结果。
