市販の放射温度計と気象庁データを利用した気温減率の測定方法の開発

抄録

In this study, we developed a method for measuring the temperature lapse rate, assuming a high school learning environment. Aiming for individual students to be able to conduct measurements as much as possible, we devised a method to calculate the temperature lapse rate by using an inexpensive infrared thermometer, combined with cloud base temperature measurements and open data from the Japan Meteorological Agency. Actual measurements were conducted at two locations in the Kanto region, and from 65 measurement results, we frequently obtained values of 0.5–0.6℃/100 m. Furthermore, an examination of measurement accuracy suggested that stable results could be obtained when the cloud base height exceeded 4,000 m.
