UV Spectroradiometer on Sun tracker for direct solar irradiance measurement and TOC determination •Precise Sun Tracker with 4 Quadrant Diode for fine alignment •Highest stray light reduction for precise TOC determination, evaluated in scientific intercomparisons to Brewer and Dobson •Compact size •Weather proof •Included software •Different spectral ranges possible (UV, VIS, NIR) The BTS-Solar has been compared to Brewer and Dobson in several scientific publications to verify and show the measurement capabilities. These showed an excellent agreement, see, long term intercomparion at DWD (Deutscher Wetterdienst) and International Intercomparion at Izaña Atmospheric Observatory/Teneriffa . Measurement system for direct spectral irradiance measurements of solar radiation. The system consistent of a BTS2048-UV-S-WP (Spectroradiometer with tube), SUT-1711 (Suntracker), SUT-Z01 (Sunfinder), SolarRunner (Software) and connection cables. Evaluations like TOC (Total Ozone Column) are supported by the measurement system. Versions with BTS2048-VL-TEC-WP (UVvisNIR) as well as BTS2048-IR-WP (IR) are also available. This is of particular interest for spectral AOD (Aerosol Optical Depth). See for example this publication: AOD with BTS
