Albedo is expected to be constant regardless of wind speed or air temperature. To verify this concept, the albedo of asphalt pavement (B2) on some days with different wind speeds and air temperatures were measured for comparison. As shown in Fig. 12. (a), the wind speed and air temperature on 2/23/2012-2/25/2012 (measured with a nearby mobile weather station) are quite different. The wind speed on 2/23/2012 is much higher than the other two days. The air temperatures on 2/23/2012 and 2/24/2012 are higher than that on 2/25/2012. The albedo and solar radiation on 2/23/2012-2/25/2012 are plotted in Fig. 12. (b). The albedos around noon are all around 0.08 on these three days. No significant variation in mid-day albedo is observed on this period with quite different wind speeds or air temperatures.
