Homogenized radiosonde record at station Ny-Ålesund, Spitsbergen, 1993-2014
Radiosonde measurements obtained at the Arctic site Ny-Ålesund (78.9°N, 11.9°E), Svalbard, from 1993 to 2014 have been homogenized accounting for instrumentation discontinuities by correcting known errors in the manufacturer provided profiles. From the homogenized data record, the first Ny-Ålesund u...
