Airborne Gravimetry with Quantum Technology: Observations from Iceland and Greenland
Abstract. We report on the availability of data from an airborne gravity campaign in Iceland and Greenland, conducted during June and July 2023. The dataset includes observations from a platform stabilised gravimeter based on cold-atom quantum technology and a strapdown gravimeter based on classical technology. The data is available in three different levels of processing making it relevant to users interesting in working with "quantum" and "hybrid" data as well as users interested in geophysical studies. The manuscript describes the data processing applied to derive the various levels of data and presents an evaluation of the data accuracy. This evaluation indicates an accuracy of 1 to 2 mGal for both sensors, depending on the roughness of the gravity field. Although the two technologies lead to similar performance, further analysis indicates that the error characteristics are different and that final estimates would benefit from a combination.
