Gallery›Digital Commonwealth — Boston Public Library›New Instrument That Records Sky Temperatures. Dr. C. H. Heck of North Carolina State College is shown above with a new weather instrument that he has developed, one that is so delicate that it can measure the temperature of drops of water a mile above the earth. By concentrating the light of the sky on a "cascade" of mirrors, according to Dr. Hecht it is possible to detect changes in temperature in the upper atmosphere, and to use such changes to predict the weather in the following 24 hours.
