Abstract

This paper presents a new method of sampling the climatic data for infrared signature analysis. Historical hourly data from a stationary marine buoy are used to select a small number of sample points (N=100) to adequately cover the range of statistics(PDF, CDF) displayed by the original data set(S=56,670). The method uses a coarse bin to subdivide the variable space (35=243 bins), and a single-point ranking system to select individual points so that uniform coverage (1/N = 0.01) is obtained for each variable. The selected sample data show good agreement to the original data set in statistical distribution. statistics(PDF, CDF) displayed by the original data set(S=56,670).
