Περίληψη	Cities have their own microclimates, which are influenced by a variety of factors. Some of these are the materials used for buildings and roads, the height and density of building, and the shapes of surfaces. This microclimate can have a significant impact on the temperature inside cities compared to rural areas, which can cause heat stress related problems for their residents[1]. The albedo of the materials is of particular importance, because it determines the total amount of radiation that is reflected by them. The remaining light that isn’t reflected by the material, is instead absorbed by it, thus increasing their temperature[2]. Therefore, it is important to understand the radiative properties of materials, the way these are connected to the shape of their surface, and their albedo. This can be achieved by measuring the radiance leaving the materials using a hyperspectral radiometer, which is able to capture a wide and continuous range of wavelengths. In this study, a method was developed to derive the albedo of materials by calculating the Bidirectional Reflectance Distribution Function (BRDF) using hyperspectral measurements taken under direct sunlight, and it was used to calculate the albedo for materials used in the city of Heraklion.
