Horizontal Scale Variations in Satellite Estimates of Weather Erosion Parameters for Reentry Systems

Abstract

A weather erosion parameter known as the Environmental Severity Index (ESI) has been estimated using infrared and visible data from satellites. Cloud sampling requirements limited the original prediction equations to satellite data averaged over a horizontal scale of 70 km. Further experiments have demonstrated great utility for satellite estimates on a scale of 10 km and also revealed some systematic differences between the coarse and the fine scale estimates. The ESI averages 1 percent to 10 percent higher for the fine scale estimates and high values of ESI are observed more frequently.
