摘要:

本文介绍了在圣皮埃尔(留尼汪岛)的全球和漫射光效的初始值。首先,所使用的数据是在2008年2月至6月的6个月期间测量的。在此期间,研究了所有定义的日型(晴天、多云和中间)。一般来说,留尼旺岛的气象数据库不包含照度值的信息。另一方面,当地气象中心拥有60年历史的太阳辐照度(W.m-2)数据库。因此,为了从太阳辐照度中找到照度(或从太阳辐射亮度中找到亮度),确定发光效率非常重要。本文对实测数据进行了分析,建立了确定不同天空条件下光效的经验常数模型。这些经验常数(模型)和现有的模型进行了比较。本文将介绍用于定义天空条件(阴天、中等天气和晴天)和日型特征以及分类的方法。

英文摘要:

This paper presents initial values of global and diffuse luminous efficacy at Saint-Pierre (Reunion Island). Firstly, data used were measured for a period of 6 months, from February to June 2008. During this period, all defined day-types have been studied (clear, cloudy and intermediate). Generally, the meteorological database of Reunion does not contain information for illuminance values. On the other hand, the local meteorological center has a 60-years-old database for solar irradiance (W.m-2). So it is important to determine Luminous Efficacy in order to find illuminance from solar irradiance (or luminance from solar radiance). The measured data were analyzed, and empirical constant models were developed and presented in this paper in order to determine luminous efficacy under different sky conditions. A comparison between these empirical constants (models) and existing models has been made. The method used to define sky conditions (overcast, intermediate and clear) and day-types characterization as well as classification will be presented in this work.
