Study of methods for estimating ultraviolet rays A,B from solar radiation

在这项研究中，我们提出了一种估算太阳总辐射中紫外线a、B的方法。几乎没有可靠的公共紫外线观测站。此外，由于紫外线仪即使在自身观测，其传感器的灵敏度也有较大的下降，数据的可靠性也成为问题。我们在4所大学进行了太阳辐射和UV-A，B的观测，提取了可靠的数据并确定了参数。此外，我们还重点研究了UV-B与臭氧的关系。总臭氧柱使用卫星观测数据。考虑了臭氧的影响，提高了估算精度。此外，我们还研究了直接紫外线和漫射紫外线的估计方法。我们证明了我们可以准确地估计紫外线的两种成分。这些估算方法适用于日本全境。

In this study, we suggested a method for estimating ultraviolet rays A,B from global solar radiation. The ultraviolet rays have few reliable public observation stations. In addition, the reliability of data becomes the problem because the ultraviolet rays meter has a big sensitivity deterioration of the sensor even if we observe it in oneself. We observed solar radiation and UV-A,B at 4 universities and I extracted reliable data and identified parameters. In addition, we focused on the relationship between UV-B and ozone. The total column ozone used satellite observation data. Estimated precision improved by considering influence of ozone. Furthermore, we examined the method for estimating of the direct ultraviolet rays and diffuse ultraviolet rays. We showed that we could estimate both ingredients of ultraviolet rays with practical precision. These estimated methods are applicable to the whole land of Japan.
