The Alma-Ata Geomagnetic Observatory provides continuous monitoring of Earth's geomagnetic field. Located at 1300 meters above sea level in the foothills of the Tien Shan Mountains, approximately 10 km from Almaty, Kazakhstan, the observatory operates state-of-the-art equipment certified by INTERMAGNET, including the fluxgate magnetometer LEMI-008 and the proton Overhauser magnetometer POS-1.

The data service includes:

The service provides open access to minute- and hour-resolution data (XYZF components and the geomagnetic K-index) from 2003 onward via the Institute of Ionosphere’s website (https://ionos.kz/). Minute-resolution variation data since 2004 are also available through the INTERMAGNET network. Data prior to 2003 are available upon request.

The dataset is maintained by the Institute of Ionosphere and is additionally accessible through the Kazakhstan Space Weather Portal (https://ssa.fai.kz/, registration required), which also offers interactive plots and visualizations.
