Yellow dots: SV and its uncertainty (vertical black lines) of the East component Y from Swarm-A data relocated at 440 km altitude over the indicated observatory locations (see main text for details). Red/blue curves: SV estimation from CHAOS-7.7 model. Note that after August 2020 the changes in the curves (blue lines) from CHAOS-7.7 are likely affected by the model regularization instead of the data (see Sect. 3 for more details)
