Macapá, a Brazilian equatorial magnetometer station: installation, data availability, and methods for temperature correction

Cristiano Mendel Martins, Katia Jasbinschek Pinheiro, Achim Ohlert, Jürgen Matzka, Marcos Vinicius da Silva, and Reynerth Pereira da Costa

Data sets

Magnetometer station Macapa, Brazil, calibrated 1-second geomagnetic data, V.1 Marcos Vinicius Da Silva, et al. https://doi.org/10.5880/GFZ.2.3.2024.002

Short summary

The magnetic equator is the region where the magnetic field is horizontal and therefore strong ionospheric electric currents occur, the so-called equatorial electrojet. The magnetic equator is predicted to be at Macapá state in 2024. Therefore, a new magnetometer station was installed in Macapá in order to track the effects of the equatorial electrojet. We present the setup and data analysis of Macapá station, and we develop a method for temperature correction of the vector magnetometer data.
