ANTARCTIC STATIONS

• Ushuaia (54º49’S, 68º19’W) CADIC
• Marambio (64º14’S, 56º38’W) DNA / IAA
• Belgrano (77º52’S, 34º37’W) DNA / IAA

NILU-UV MULTICHANNEL RADIOMETER

• Five UV channels centered at: 305, 312, 320, 340 and 380 nm (10nm FWHM)
• PAR (Photosynthetical Active Radiation) 400-700nm
• Stabilized temperature: 40 ºC
• Products:

Total ozone content

Radiation UV-A and UV-B

Clouds transmission factor (CLT)

Biologically effective UV doses (CIE)

QUALITY CONTROL NILU-UV (Agencia Estatal de Meteorología, AEMET / CIAI)

• Two 100-W working lamps every 15 days and one control lamp every three calibrations

QUALITY ASSURANCE (Finnish Meteorological Institute, FMI)

• Traveling reference NILU-UV transfers calibration factors from the absolute reference spectroradiometer by direct comparison with the instruments at Ushuaia and Marambio twice a year. The NILU-UV from Belgrano is replaced every year by another instrument previously calibrated at the Izaña Atmospheric Research Center.
