Nigmatullin R.R.; Bataleva E.A.; Nepeina K.S.; Matiukov V.E. Quality control of the initial magnetotelluric data: analysis of calibration curves using a fitting function represented by the ratio of 4th-order polynomials // Measurement, 2023, 216, 112914, https://doi.org/10.1016/j.measurement.2023.112914.

Highlights:

• Universal fractional calculus fitting curve enables to fit 4 normalized calibration curves.
• The standard deviation between the tested box and the pattern box in average is at least than 1%.
• The calibration curves identity proves the high quality of field data in mountainous conditions.
• The pair of “amplitudes” and “degrees” – 4 calibration curves in total, are observed with the fitting function as two polynomials ratio of fourth degree function F(x) containing 9 fitting parameters (C₀-₇, B₀), simply calculated as numeric constants through linear least squares method (LLSM).
• The relative error evaluating the fitting 9 parameters (C₀-₇, B₀) is less than 0.25%.
• Routine calibration process could be used as an etalon searching in the normalized form.
• The fitting parameter D demonstrates “a quality” of calibration of the tested box compared with the reference one.

Results of RS RAS activity - for the Russian Science Day

   Traditionally, February 8 is celebrated as the Day of Russian Science - a holiday dedicated to the date of the Russian Academy of Sciences foundation, established by Peter the First in 1724.

   On the eve of such important date for the entire Russian scientific community, as well as on the eve of the anniversary year of the Russian Academy of Sciences, the Research Station of the Russian Academy of Sciences sums up the results of 2022.

   According to the results of R&D 2022, two most important results were obtained:

1. A new measuring "strategy" in the method of electrotomography was proposed and its performance was evaluated using a model experiment (synthetic data);

2. Identified pre-seismic correlated anomalies of spatial and temporal temperature changes in the lower atmosphere and the total electron content of the ionosphere.

   Of course, the list of results obtained by the RS RAS staff in 2022 is not limited to the above two, and a more extended idea of RS RAS findings can be obtained from the scientific papers published this year in highly ranked Russian and foreign journals and in the proceedings of international conferences. 

   Also in 2022, the joint scientific workshop of Institute of Physics of Earth of RAS and RS RAS "Geological and Geophysical Monitoring of Tien Shan Lithosphere" continued its work. 23 online meetings were held at the workshop in 2022 to discuss new results, methods and problems of geological and geophysical monitoring of modern geodynamic processes, study of physical and chemical properties of rocks, the stress-strain state of the Earth's crust in seismically active regions and other topical issues in the field of Earth sciences and related fields of theoretical and experimental physics.
