In the open air, reflected solar radiation by the surroundings is having an effect on the measurement error. To estimate solar reflectivity of the target surface, white and black board, their insolation reflectivity is known、are placed on target surface and measured each reflectivity. In this method, there is a possibility causing error by gloss difference of the black, white and target surface. In the ordinary paint, considerable deviation arises with the result when the gloss differences are large. In the cool paint, it is confirmed that there is no clear influence on the result from the gloss, because of high reflectivity of the wavelength range with a large amount of diffused solar radiation.

在露天中，周围环境反射的太阳辐射对测量误差有影响。为了估计目标表面的太阳反射率，白板和黑色板，它们的隔离反射率已知，将其放置在目标表面并测量每个反射率。在这种方法中，有可能导致黑色，白色和靶表面的光泽差异导致错误。在普通油漆中，当光泽差异很大时，会产生相当大的偏差。在凉爽的油漆中，可以证实，由于波长的高反射率具有大量扩散的太阳辐射，因此对光泽的结果没有明显的影响。
