| Research Abstract |
Following the Heisei 14 fiscal year, the standard SAT meter was created and it continued the weather observation in the Hachioji area. We got weather observation data of the Aerological Observatory. We analyzed about each characteristic and correlation, and acquired knowledge, such as difference to the characteristic acquired by the previous year.
In order to verify the practicality of the estimation formula in a larger area, we observed weather in Hachioji-city, Tokyo (Kogakuin University Hachioji school building) and the area along the shore (Yamada-town, Shimohei-gun) of Iwate. We clarified high precision the estimation formula and created atmospheric radiation quantity map for natural energy use. As a result, as for the tendency of the amount of air radiation in Japan, a possibility of the value having become large and being further influenced of above sea level was shown like the south direction.
Furthermore, these estimation formulas were used for verification of the environmental

improvement effect by the rooftop greening which attracts attention as new natural energy use for the purpose of examining atmospheric radiation quantity proposed so far, and the practical validity of the amount presumption formula of nocturnal radiation quantity in the current fiscal year. By this verification, atmospheric radiation quantity income and outgo in the roof surface of a specific building was calculated from the actual measurement and the estimation value, and accuracy verification of a estimation formula and the practical problem were extracted by comparing both.
It can be said that these results are precious knowledge in the point that presumption of atmospheric and noctural radiation quantity shows that it is effective to examination of a natural energy use system, and did not depend on a simulation that it is a estimation formula applicable also not only in the radiant heat income and outgo in the surface of a specific building but earth surface, but clarified by survey.
