Geomagnetic observatory
Оn the basis of the laboratory of geomagnetic research operates geomagnetic observatory Alma-Ata
The Alma-Ata Geomagnetic Observatory performs continuous monitoring of the geomagnetic field on the territory of the Republic of Kazakhstan.
In November 2005, the Alma-Ata Geomagnetic Observatory received a quality certificate from the INTERMAGNET International Organization.
Changes in the state of the geomagnetic field for 2003-2019 are presented on the website of the geomagnetic observatory “Alma-Ata” http://geomag.ionos.kz, as well as on the website of the International Network of Geomagnetic Observatories INTERMAGNET www.intermagnet.org. Since 2010, the Alma-Ata geomagnetic observatory has been part of the International Network of Stations for the normalization of the Dst-index, and real-time data are transmitted to the Dcx-index Server (University of Oulu, Finland) http://dcx.oulu. fi. All data of the Alma-Ata geomagnetic observatory comply with INTERMAGNET international standards. These observatories are intended for detailed studies of various geomagnetic processes occurring in near-Earth outer space.
Mission: Monitoring of the full vector and field components according to the INTERMAGNET international network standard in order to:
development of the international reference model of the geomagnetic field IGRF;
study of geomagnetic field variations and their causes;
study of seismo-magnetic links;
geomagnetic situation forecast;
providing information about the variations of the field of interested consumers (JSC “Kazakhstan GIS Center” of the Ministry of Defense of the Republic of Kazakhstan, GKP “Urban Cadastre”, RSE “Qazgeodezia”)
Observatory measuring instruments
All measurements of the geomagnetic field are carried out using a specialized complex. The complex consists of two digital magnetic variation stations based on fluxgate magnetometers LEMI-008 and LEMI-018 for recording the XYZ-components of the geomagnetic field in a 1-second mode, a variational station with a POS-1 proton magnetometer for absolute measurements of the modulus of the geomagnetic field vector F in 5- and DI fluxgate magnetometer LEMI-203 for absolute measurements of magnetic declination angles D and inclination I.
Magnetometers have certificates and are verified every 2 years according to the INTERMAGNET program.
Main works within the observatory
The observatory has organized a geomagnetic service, which provides for daily analysis and, if necessary, removal of interference in the received second data, calculation of minute values from the initial data, as well as calculation of the K-index of local geomagnetic activity and sending files of minute values to the WDC INTERMAGNET.
Comprehensive monitoring measurements carried out at the Alma-Ata Geomagnetic Observatory also include measurements of the angular elements of declination D and inclination I of the geomagnetic field vector. These measurements are carried out using a fluxgate DI magnetometer LEMI-203. In accordance with the agreement, annual calculations of the declination of the magnetic needle D and annual changes in declination D are carried out according to the coordinates of points for JSC “Kazakhstan GIS Center” of the Ministry of Defense of the Republic of Kazakhstan. Also, calculations of the geomagnetic declination D were carried out for the State Enterprise “Urban Planning Cadastre” under the Department of Architecture and Urban Planning of the Akim of the Almaty Region.
According to the experimental geomagnetic data, the average annual values (D, I, H, Z, X, Y, F) are calculated and prepared – the component of the geomagnetic field for the Summary tables “Annual average values of the geomagnetic field of the World Network of Magnetic Observatories” IZMIRAN.
