The Hemispheric Eighth Mesh Terrain Elevation and Geography Data Sets

Abstract

A number of meteorological models at the Air Force Global Weather Central (AFGWC) make use of eighth mesh resolution terrain elevation and geography (land/coastline/water) data sets. Unfortunately, the data sets currently in use at AFGWC are of extremely poor quality. Therefore, as part of GL efforts to upgrade the Real-Time Nephanalysis Model, new hemispheric eighth mesh (approximately 25 nautical mile resolution) data sets were developed. The global Navy 10 arc minute terrain elevation and land characteristics data (approximately 10 nautical mile resolution) were used as source data. This report describes the averaging and remapping techniques used in the development of these new accurate hemispheric data sets.
