COV-OBS.x2: 180 years of geomagnetic field evolution from ground-based and satellite observations
Abstract We present the geomagnetic field model COV-OBS.x2 that covers the period 1840–2020. It is primarily constrained by observatory series, satellite data, plus older surveys. Over the past two decades, we consider annual differences of 4-monthly means at ground-based stations (since 1996), and...
