Albedo variations with respect to different weather conditions with the observed shortwave radiation data over Arabian Sea using Pyranometer, during June to August 2002, and March -June 2003. The hourly albedo variations are analysed and presented in relation with solar altitude (SinH) and transmission factor (TF). TF classified into three groups: under clear sky (TF > 0.65), partly cloudy (0.4 < TF < 0.65) and overcast condition (TF < 0.4). As per classification, the mean albedo (TF) values are 0.07 (0.71), 0.06 (0.59) and 0.07 (0.30), respectively. The study period includes different weather conditions such as clear sky to overcast conditions and different wind conditions. During the lower wind speeds, albedo is varying between 0.01 and 0.17 and TF varied between 0.16 and 0.73. However, during higher winds (> 12 m/s), there is no significant changes observed in albedo. Variations in TF and albedo during the overcast conditions are significant, however wind also dominating.

不同天气条件下阿拉伯海反照率与太阳高度和传输因子的关系

2002年6月至8月以及2003年3月至2003年6月期间，利用比热计在阿拉伯海观测到的短波辐射数据，得出了不同天气条件下的反照率变化。系数（TF）。TF分为三类：晴天（TF> 0.65），部分多云（0.4 <TF <0.65）和阴天（TF <0.4）。根据分类，平均反照率（TF）值分别为0.07（0.71），0.06（0.59）和0.07（0.30）。研究期包括不同的天气条件，例如晴朗的天空到阴天的条件以及不同的风况。在较低的风速下，反照率在0.01和0.17之间变化，而TF在0.16和0.73之间变化。但是，在大风（> 12 m / s）下，反照率没有明显变化。在阴天条件下，TF和反照率的变化很大，但是风也占主导地位。
