ASPAM. Atmospheric Slant Path Analysis Model Statistical Paired Differences PilotStudy for Sample Size Determination

摘要

Describes methodology and results of a pilot study intended to determine therequired sample size for a statistically significant seasonal study of the differences between ground truth (represented by upper-air soundings) and (1) Atmospheric Slant Path Analysis Model (ASPAM) optimum interpolation vertical profiles (OIVPs) and (2) alternate vertical profiles. This study builds on earlier ASPAM studies, incorporating lessons learned and user feedback. It found that a sample size of 50 observations was enough to determine if the differences between ground truth (upper-air soundings) and ASPAM vertical profiles were significant at the customer's confidence level....
