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.

扩充的AMeDAS天气数据（以下简称E-AMeDAS）包含日本20年的842个站点，是气象厅对AMeDAS数据的整理，并于2005年出版。为了有效地使用E-AMeDAS，有必要加强现有版本中未收集的数据，如UV-A，UV-B，PAR等。为了建立气象量的估算模型，开始了收集基础数据的测量。在秋田县立大学、东京都市大学、大坂市立大学和鹿儿岛大学的先前测量站中引入了照度、UV-A、UV-B、PAR传感器。对辐射照度、照度、UV-A、UV-B、PAR、气温、湿度、风向风速等多个观测站的测量系统进行了改造。长期测量于2006年1月1日开始， ...更多信息在此基础上，详细分析了紫外辐射与辐照度的关系。利用晴空指数和晴空指数对天空状况进行分类的方法，对建立由辐射照度估算UV-A和UV-B的表达模型具有一定的指导意义。将E-AMeDAS中先前推荐的用于从辐照度估计照度的模型与测量数据进行比较，并确认了高精度。提出了估算全球直接辐射的基本模型。对从风向、风速、降雨量等长时间间隔值推算1分钟间隔值的方法进行了研究。为了进一步强化E-AMeDAS，计划继续进行测量，并根据长期连续测量获得的数据开发各种气象量的推算方法。基于这项持续研究工作所取得的成果，下一版本的先进的E-AMeDAS将很快提供给许多用户，这些版本可以有效地使用和多用途。少
