For the purpose of setting up engineering standards the U. S. A. F. was requested to determine standard cold and hot atmospheres from 60,000 feet to 100,000 feet. Data were too scarce to use conventional statistical techniques and an alternate method is presented herein. Included are graphs of the cold and hot atmospheres for each of four latitudinal zones from sea level to 100,000 feet, and a table of heights and temperatures at critical points along straight-line envelopes enclosing all zonal curves.
