 ===== Principle =====
+Two pyranometers (CMP 21), a pyrheliometer (CHP 1) and a pyrgeometer (CGR 4) are used to measure solar shortwave radiation and terrestrial longwave radiation. One pyranometer receives total downward solar irradiance. The other instruments are mounted on a suntracker (SOLYS 2) measuring diffuse downward solar irradiance (shaded pyranometer), direct solar irradiance (pyrheliometer) and terrestrial downward irradiance (shaded pyrgeometer). All instruments were produced and calibrated by Kipp&Zonen B.V., Netherlands.
