<md:abstract>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 MIN as additional information on the site's surroundings.</md:abstract>
