Zusammenfassung
Instituto Português do Mar e da Atmosfera (IPMA) operates an observatory in São Teotónio, Alentejo Region, Portugal, for seismic, magnetic and other observations. This observatory also provides ideal conditions to operate an INTERMAGNET-type geomagnetic observatory, including a nonmagnetic underground building for a variometer and a non-magnetic building for absolute measurements. In May 2019, IPMA and Observatory Niemegk/GFZ Potsdam installed a Geomag 01 variometer loaned from GFZ's instrument pool. For absolute measurements, a Mingeo 010 theodolite and a GSM-19 scalar magnetometer is used. Additionally, a Geometrics G-862RBS cesium magnetometer is recording geomagnetic field strength with 10 Hz. With some intermediate modifications, the Geomag 01 magnetometer was used until July 2022, and sometimes electric field was also measured at the observatory. In July 2022, a FGE variometer with two analogue outputs and two data loggers and a GSM-90 scalar magnetometer was installed. The new loggers have real-time capability and the whole system is supported by a uninterruptible power supply. In spring 2023, we plan to apply for INTERMAGET participation. Here, we describe the various observatory setups and the recordings collected since May 2019 and bring them into context with other observatory time series from the Iberian Peninsula.
