We present the results of the geomagnetic measurements of the new Spanish Repeat Station network that have been carried out in 2015, 2016 and 2017.
The network currently consists of 42 stations distributed among Iberian Peninsula and Balearic Islands, which are measured every three years. The measurements are made with a Di-flux Bartington mounted in a theodolite Zeiss 020B and a G-856 proton precession magnetometer. Also a FGE variometer and a Gem Gsm19 Overhouser magnetometer are used for the variometer stations.
The measurements are reduced using the following Intermagnet observatories: San Pablo-Toledo (SPT), Ebro (EBR) and San Fernando (SFS).
Also we show the magnetic cartography obtained for the epoch 2015.0 in the components D, H, Z and F with their secular variation. |
