DTED (Digital Terrain Elevation Data) Study

Abstract

Terrain height errors have significant effects on studies sensitive to atmospheric quantity and structure, such as USAFETAC's atmospheric profiles (point analyses). A recent study concluded that the primary source of degradation in atmospheric profile quality was caused by the coarse grid spacing of the eighth-mesh terrain data used in the Air Force Global Weather Central (AFGWC) Atmospheric Slant Path Analysis Model (ASPAM). This report documents a study that determines the feasibility of incorporating the Defense Mapping Agency (DMA) high density Digital Terrain Elevation Data (DTED) into the AFGWC atmospheric profile model. The report also describes a procedure developed by USAFETAC to make the dataset smaller and save computer storage space.
