magnetic observatory baselines; quasi-definitive data
Sažetak
The accuracy and availability of quasi- definitive (QD) data from magnetic observatories greatly depends on several factors. The absolute accuracy mostly depends on quality of absolute observations and variability of the variometer baseline. Processing protocols and skills of the data processor are crucial factors for prompt delivery of QD data. More and more observatory networks have to be operated by limited numbers of staff, in parallel with progress in technologies necessary for operating unmanned observatories. In cases when a single person is in charge for operating several variometer systems, the production of QD data can be a quite laborious and time consuming task. This will be especially pronounced with an increase of measured base values if automatic absolute instruments will be used in observatories. To obtain the data with high absolute accuracy in near real-time, we are designing a routine for the automatic determination of the “best” temporary baselines. This routine is robust to outliers and flexible enough to properly fit various types of the baseline variability. The results of comparison between definitive baselines obtained with the new routine and ones reported by INTERMAGNET observatories for the period 2009-2011 will be presented. Also, the differences between newly calculated definitive and simulated temporary baselines will be shown.
