Daily mean and standard deviation values of ASM_V scalar residuals. Values are given in nT from 1 January 2014 to 31 December 2014. No flag filtering is applied on the ASM_V data. The specific/noisier behavior of the ASM FM3A instrument on Swarm Charlie is very clear (until the anomaly of 5 November 2014 and the subsequent loss of ASM vector data). Note also the peaks in the standard deviations of Alpha and Bravo, corresponding to times of satellite maneuvers during commissioning.
