Description

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 – 40 GHz, at the Onalsa Space Observatory. The simulations are carried out with or without liquid cloud water in the atmosphere. The normalized power-pattern of the antenna is also provided.

We have used atmospheric data from ECMWF and processed them with the open software package ARTS. Details are described in the published paper:
Forkman, P, Flygare, J and Elgered, G (2021).
