A collection consists of several datasets that are in some way connected. They can belong to the same research series, research infrastructure, or come from the same research expedition.

We also provide access to the special collections “Swedish party programs and election manifestos” and the Swedish Gallup Institute's public opinion surveys from 1942 to 1956.

  • Atmospheric horizontal gradients measured with eight co-located GNSS stations and a microwave radiometer

We have used eight co-located GNSS stations, with different antenna mounts, to estimate atmospheric signal propagation delays in the zenith direction and linear horizontal gradients. The gradients are compared with the r...

  • Simulated microwave propagation delays and atmospheric sky brightness temperatures in the frequency range 14–40 GHz at the Onsala Space Observatory

The dataset contains time-series of signal propagation delay due to water vapour, liquid water path, and multi-dimensional time-series of atmospheric brightness temperature and transmission, in the frequency range 14 – 4...
