  • The dataset contains minute mean values of the geomagnetic field expressed as northward component X, eastward component Y, and vertical (downward) component Z as measured at the geomagnetic observatory Villa Remedios, Bolivia, for January 2013. Villa Remedios (preliminary code VRE) is operated in cooperation by the university Universidad Mayor de San Andrés in La Paz, Bolivia, and GFZ German Research Centre for Geosciences since the end of 2002. The observatory is not yet an INTERMAGNET observatory and so far, no data has been submitted to any World Data Centre for Geomagnetism. However, preliminary geomagnetic data (minute means) from Villa Remedios are available upon request from GFZ. Please note that a dataset based on the data provided here will be submitted to the WDC for Geomagnetism at a later stage and might differ slightly due to calibration and removal of outliers. Villa Remedios is located about 650 km south of the magnetic equator and about 930 km south-east of the geomagnetic observatory Huancayo (IAGA code HUA, Peru). This makes VRE a suitable observatory to be used in conjunction with HUA to isolate and study the equatorial electrojet signal at Huancayo. The data file is in ASCII format and contains blank-separated the year (YYYY), the month (MM), the day (DD), the time (UTC) in the format, the X component in nanotesla (nT), the Y component in nT, the vertical component Z in nT, the total geomagnetic field F in nT measured with an independent, auxiliary scalar magnetometer, and, finally, the difference (in nT) between F measured with the auxiliary scalar magnetometer and the total field calculated from the components X, Y and Z. Components X, Y and Z are measured with an FGE variometer (serial number S0199, E0213 built by DTU Space, Technical University of Denmark) and in this data file, they are preliminarily calibrated and given in nanotesla (nT). These values are minute means and filtered from spot readings by an INTERMAGNET Gauss-shaped filter. The scalar magnetometer is a GSM90F1 by Gemsys, Canada. The data logger is a Flare+ by British Geological Survey. Geomagnetic observatories are described in e.g. Jankowski and Sucksdorf (1996), in Matzka et al., (2010) and Matzka (2016).
