Sunshine and Radiation Data (1981 – 2010)

These sunshine and radiation data were calculated using the radiation model STRAHLGRID of the ZAMG. The model takes into account solar position, atmospheric turbidity and cloudiness calculated from station measurements of sunshine duration. Topographical shading and other terrain effects (area and multiple reflections) are accurate, but the close shading (e.g. through buildings or vegetation) is not taken into account.本套日照与辐射数据基于奥地利气象与地球动力学研究所（ZAMG）的STRAHLGRID辐射模型计算生成。该模型将太阳位置、大气浑浊度，以及由台站日照时长观测数据推算得到的云量纳入考量范畴。模型对地形遮蔽及其他地形效应（包括面积效应与多重反射）的计算结果准确可靠，但未考虑诸如建筑物或植被造成的近距离遮蔽情况。
