GUV total ozone column and effective cloud transmittance from three Norwegian sites 1995-2019 (Version v1.0) T. M. Svendby https://doi.org/10.5281/zenodo.4446609

Short summary

Measurements of total ozone and effective cloud transmittance (eCLT) have been performed since 1995 at three Norwegian sites with GUV multi-filter instruments. The unique data sets of high-time-resolution measurements can be used for a broad range of studies. Data analyses reveal an increase in total ozone above Norway from 1995 to 2019. Measurements of GUV eCLT indicate changes in albedo in Ny-Ålesund (Svalbard) during the past 25 years, most likely resulting from increased Arctic ice melt.
