Fluctuations at surface albedo measurements are widely known because of seasonality, weather, and heterogeneity on the ground, among others. Additionally, even some studies provide an analysis of cloud enhancement (CE) and albedo enhancement (AE) due to sky cloudy conditions. In this paper, we report about surface albedo longterm changes under different weather conditions compared to a clear sky reference dataset built up using two different measurement systems and two different soils. A good statistical relationship between cloudiness and surface albedo long term stability has been found. The final results exposed in this paper will help to optimize the duration and characteristics of the albedo measurement campaigns.
