Single versus daily vector calibration process. The upper graph displays the low-pass-filtered ASM scalar residuals obtained with the ASM-V product (daily vector calibration), while the lower ones display the ASM vector data using the same vector algorithm with a single and constant set of vector calibration parameters without (middle graph) and with (bottom graph) external inputs for the correction of seasonal effects. All residuals are plotted in nT from 1 January 2014 to 31 December 2014.
