A collection of measurements of radio propagation in the KA/Q band measured from various European sites using the Aldo Paradoni Payload (TDP5) propagation beacon.

Measurements were made at 20 and 40 GHz frequencies.

The measurements were made as part of the ESA funded ASALASCA (Large Scale Assessment of KA/Q band atmospheric channel using the ALPHASAT TDP5 Propagation beacon) project.

The collection is additionally supplemented by surface meteorological measurements from the Chilbolton Observatory, Hampshire, UK for use in conjunction with the radio propagation measurements made at Chilbolton.

Measurements began in July 2016 and are presently ongoing.
