Paper Abstract

UV-SPRAFIMO is a completely new developed UV instrument for very fast measurements of solar spectral irradiance with high spectral resolution and arbitrary step width. It combines sophisticated filter radiometer technique with a new model based on neural networks. UV-SPRAFIMO has the following specifications: (1) Spectral region 280 - 400 nm. (2) Arbitrary spectral resolution and step width of the UV spectra (≥ 0.05 nm). (3) Simultaneous measurement of all spectral channels. (4) Up to 5 measurements per second with arbitrary averaging interval of 5 to 30 seconds. (5) Weatherproofed, air conditioned housing and fully automatic measurement system. (6) No moving parts. (7) Data logger up to 64 Mbytes memory for long-term measurements at remote sites. (8) GPS to automatically set up time and geographical position data. (9) PC based, graphical user interface for measurement set up and monitoring and processing of data. (10) Online calculation and visualization of integrated irradiances like UV-A, UV-B and UV-Index as well as erythemal or user defined weighted irradiance. (11) Simultaneous total ozone column retrieval from spectral measurements. UV-SPRAFIMO is a standalone and easy to use UV spectral radiometer; it was tested in different climate regions during field measurement campaigns in order to compare measurement performance and accuracy to high quality scanning spectral radiometers. Details of functional principles and results of the measurement campaigns are presented.
