G. Seckmeyer (IMuK, U. Hannover) — IMuK UV spectroradiometer, approved as an NDACC traveling standard UV spectroradiometer. The instrument is based on a Bentham DTM300 scanning double monochromator spectroradiometer (0.5 nm bandwidth) and uses three detectors (PMT, silicon diode, PbS diode) for covering a spectral range of 280–2500 nm. The system affords measurements of spectral UV irradiance and spectral radiance distributions under all-weather conditions. The entrance optics are aligned by an all-weather two-axis positioning unit, which can also be used under Antarctic weather conditions. The system participated in the 2003 North American interagency intercomparison of ultraviolet spectroradiometers, which was organized at the Table Mountain Observatory close to Boulder, Colorado. This instrument currently has data archived for Izaña (Tenerife), Spain (see latter entry).
