| Outline of Final Research Achievements |
We have attempted to detect greenhouse effect of the Earth atmosphere in the laboratory for science education. We designed an experimental device to control precisely the output of a tungsten lamp representing the Sun and to set a window for the air storage tank (filled by nitrogen or carbon dioxide) which is transparent over the visual to mid-infrared wavelengths. In addition, we installed the device in a large freezer to cool it down to -40 Celsius to avoid the mid-infrared emission from the surroundings. As a result, we could not establish the reproducibility of the experiments, but we understand better what is necessary to realize such an experimental device to detect of the greenhouse effect.

| Academic Significance and Societal Importance of the Research Achievements |
地球温暖化の主要因として、今や温室効果は極めて重要なキーワードとなっている。しかし、その原理は正しく理解されておらず、むしろ誤った理解が社会に浸透している。温室効果を実験室で検出したとする報告例はいくつかあるが、その殆どは誤解に基づく温室効果ではない物理量（気体の比熱の違い）の計測に過ぎず、温室効果の信頼できる検出例は皆無といってよい。本研究が成功すれば、社会的・学術的に、大きなインパクトをもたらすものと思われる。
