System upgrade and data evaluation of the AIRIS riometer

Abstract

The focus of this thesis has been to investigate how to improve the AIRIS data. This has been done by first of all giving the riometer system an overhaul, checking the wiring and receivers as well as upgrading the riometer computer harddisk. As there has been a lot of issues occurring along the way, the focus finally went to pinpointing exactly what is causing the data quality to be poor and coming up with solutions to fix this. It was found that the temperature control system has a severe e↵ect on the data quality, causing huge fluctuations in the data, and actions needs to be taken in order to solve this.
