Horizon at station Gandhinagar

The ideal site for the measurement of solar and terrestrial radiation for meteorological purposes is one that has a completely flat horizon. The WMO Guide to Meteorological Instruments and Methods of Observation (WMO No. 8) recommends that if possible no obstruction should be present, particularly within the azimuth range of sunrise and sunset over the year. This dataset describes the horizon at the BSRN radiation site GAN as additional information on the site's surroundings.用于气象领域太阳辐射与地面辐射测量的理想站点，需具备完全平坦的地平线。世界气象组织（World Meteorological Organization，WMO）《气象仪器与观测方法指南》（WMO第8号手册）建议，在条件允许的情况下，站点周边不应存在任何遮挡物，尤其需规避全年日出与日落时段对应的方位角范围内的遮挡。本数据集将基准地面辐射观测网（Baseline Surface Radiation Network，BSRN）GAN辐射观测站点的地平线状况，作为该站点周边环境的补充信息进行了描述。
