    NIWA UV spectrometer systems

    NIWA has been engaged in an active UV research programme since the 1980s. The cornerstone of this work is the routine accurate measurement of the spectrum of surface UV irradiance to quantify UV climatologies, to understand the causes of UV variability (temporally and spatially), and to monitor long-term changes.
