项目摘要

The Expanded AMeDAS Weather Data (referred to E-AMeDAS hereafter), which contained 842 sites for 20 years of Japan, is the arrangement of the AMeDAS data by the Meteorological Agency, and was published in 2005. To use the E-AMeDAS effectively, it is necessary to reinforce the data, which are not collected in the current version, such as UV-A, UV-B, PAR, etc... The measurement to gather the basic data was started aiming to develop the estimation model of the meteorological quantities. The sensors of illuminance, UV-A, UV-B, PAR were introduced into the previous measurement stations of Akita Prefectural University, Tokyo Metro University, Osaka City University, and Kagoshima University. The measurement systems in those stations containing a lot of quantities such as the irradiance, the illuminance, UV-A, UV-B, PAR, the air temperature, the humidity, the wind direction and velocity, and so forth were restructured. The long term measurement was started on January 1, 2006 and the data have … More been gathered in every one minute.The relationship of the UV radiation and the irradiance was examined in detail based on the measurement data. The method of classifying the sky condition by the clear sky index and the clear sky index was confirmed to be powerful to the development of the expression model to estimate the UV-A and UV-B from the irradiance. The previously recommended model in the E-AMeDAS to estimate of the illuminance from the irradiance was compared with the measurement data, and the high accuracy was confirmed. A basic model of estimating global-to-direct irradiance was proposed. The method to estimate the 1 minute interval values from the long time interval values concerning the wind direction and velocity, and the amount of rain fall were examined.To reinforce the E-AMeDAS further, it is scheduled that the measurement will be continued and the estimation method of various meteorological quantities will be developed based on the data acquired by a long-term, continuous measurement. Based on the results achieved by this continuous research work, the sophisticated E-AMeDAS of next version that can be used effectively and multipurpose will be provided for a lot of users soon.

扩展AMeDAS天气数据（以下简称E-AMeDAS）是气象厅对AMeDAS数据的整理，于2005年发布，包含日本20年来的842个站点。为了有效地使用E-AMeDAS，有必要加强当前版本中未收集的数据，例如UV-A、UV-B、PAR等...收集基础数据的测量旨在开发气象量的估算模型，将照度、UV-A、UV-B、PAR 传感器引入秋田县立大学、东京地铁大学、大阪市立大学和鹿儿岛大学的先前测量站。这些站的测量系统包含辐照度、照度、UV-A、UV-B、PAR、气温、湿度、风向和风速等。 2006年1月1日开始进行长期测量，每分钟收集一次数据。根据测量数据详细研究了紫外线辐射和辐照度的关系。晴空指数和晴空指数被证实对于开发从辐照度估计 UV-A 和 UV-B 的表达模型非常有用，之前在 E-AMeDAS 中推荐的模型用于估计。这将辐照度的照度与测量数据进行比较，证实了估计全局到直接辐照度的基本模型从长时间间隔值估计1分钟间隔值的方法。对风向、风速以及降雨量进行了检查。为了进一步加强E-AMeDAS，预计将继续进行测量，并根据获得的数据开发各种气象量的估算方法从长远来看，基于这项持续研究工作所取得的成果，能够有效使用且多用途的复杂的E-AMeDAS很快就会提供给很多用户。
