Utilización del radiómetro multicanal de ancho de banda moderada NILU-UV6 en la red antártica del proyecto MAR

Abstract

During the last years multichannel moderate bandwidth filter instruments have been used for UV radiation measurement and the reconstruction of the solar spectra. These instruments are now part of several UV and ozone monitoring networks, due to its easy management, low maintenance, robustness and high efficiency. In this work the characteristics, the algorithms for different products calculation, and the quality control and quality assurance system of the multichannel filter radiometer NILU-UV6 are presented. This instrument measures at five UV channels (305, 312, 320, 340 and 380 nm) and PAR (400-700 nm) channel. A radiative transfer model is used to calculate the total ozone content, clouds transmitance and the biologically effective UV doses. The preliminary results obtained by the NILU-UV6 instruments of the MAR project (Measurement of Antarctic radiance for monitoring the ozone layer) Antarctic network, managed by the Instituto Nacional de Meteorología (INM) and the Instituto Nacional de Técnica Aeroespacial (INTA), are also shown and discussed.
