Assessment of Natural and Climatic Factors (the Earth’s Magnetic Field) in Selected Territories: Report 1

Background: A man is constantly exposed to numerous environmental factors, including meteorological conditions of the earth and space weather. The study of human health effects of these factors is of increasing interest both for science and practice.

Objective: To compare instrumental and computational methods for assessing the Earth’s magnetic field in selected territories for further identification of priority natural and climatic factors and development of region-specific measures for adaptation of the local population to climate change, which should be taken into account when conducting social and hygienic monitoring.

Methods: Instrumental measurements of the Earth’s magnetic field strength were carried out in the Moscow, Voronezh, Rostov, and Krasnodar regions of the Russian Federation in August 2020. The total number of measurements was at least 15 at each point. The studies were conducted in accordance with the existing approved standard.

Results and discussion: The study areas were selected at different latitudes (from north to south) determining natural and climatic conditions of these regions. Results of instrumental measurements demonstrated the absence of significant differences between values of the Earth’s magnetic field strength at daytime and at night, possibly due to the measurement error of the MTM-01 three-component magnetometer, and ranged from 37.1 to 40.51 A/m. We observed an increasing northward trend in the Earth’s magnetic field strength (from the Krasnodar to Rostov, Voronezh, and Moscow regions). The estimated values of the magnetic field strength varied from 39.9 to 42.19 A/m. Our findings correlate with previously estimated values of the Earth’s magnetic field.

Conclusions: We conducted instrumental studies complying with existing models for estimating the Earth’s magnetic field strength, thus enabling application of our estimates in scientific research
