Ceilometer cloud base height from station Ny-Ålesund (2017-08 et seq)

Clouds are a key factor for the Arctic amplification of global warming, but their actual appearance and distribution are still afflicted by large uncertainty. On the Arctic-wide scale, large discrepancies are found between the various reanalyses and satellite products, respectively. Although ground-based observations by remote sensing are limited to point measurements, they have the advantage of obtaining extended time series of vertically resolved cloud information. The presented data set provides cloud base height measured by Vaisala CL51 laser ceilometer at Ny-Ålesund, Svalbard (78.92°N, 11.92E), and will be updated regularly by new data.
