The International Association of Geomagnetism and Aeronomy (IAGA) is one of the associations under the International Union of Geodesy and Geophysics (IUGG) and acts as a non-governmental body to serve scientists and decision-makers in research establishments, government agencies, intergovernmental bodies, and private enterprises. IAGA promotes the work of Earth and space scientists studying the magnetic and electrical properties of the Earth, other planets, the Sun and their phenomena, and interplanetary bodies.Since December 2019, IAGA has had a dedicated social media group (under the Interdivisional Commission on Education and Outreach - ICEO) to promote the work of the organisation and encourage the building of an online community. IAGA social media platforms (including Twitter, Instagram, Facebook, LinkedIn, YouTube, and a blog) started as an alternative version of mailing lists but have expanded into creating original content. We aim to provide an easily accessible platform for news and an online community for IAGA members; to increase awareness of the varied work of IAGA, both within the community and to the general public; and to promote the work of early career researchers (ECRs) and under-represented groups in IAGA. In this talk we present the successes of our most recent undertaking, the filming of outreach materials. These have fallen into two main categories: 1) outreach films, and 2) filmed interviews with IAGA (and wider IUGG) members.Evidence of success in the first category include the “Magnetic Mosaic” film (directed by Katia Pinhero), which was a finalist film in the “Women in GeoScience” category and finished 5th in the Public Choice at the Earth Futures Film Festival out of 972 initial entries. In this film 10 female scientists take the viewer on a tour as they build a magnetic mosaic from the Earth’s core into the solar system. We have also won a grant to facilitate a children’s outreach project where puppet theatre is used for Bimbim the dog to learn the differences between planets in the solar system with his friends.Secondly, we have won an outreach Grant from the IUGG where we will produce a documentary and short movies containing interviews with researchers to connect a variety of subjects under the 8 IUGG associations. The documentary will be about the structure and science of IUGG while the short movies will contain interviews of Early Career Researchers. We wish to promote this ongoing work and direct listeners to how to access these materials for their own use.

Using 12-year-long series of data (2001-2012) from geomagnetic observatories and repeat stations in Austria and its neighboring countries, a regional spatial-temporal (ST) model is developed based on the polynomial expansion consisting of latitude, longitude, and time of the geomagnetic field components and total magnetic field F. Additionally, we have used three different global models (CHAOS-5, POMME-9, and EMM2015), which are built on spherical harmonics up to a maximum degree Lmax and give the core field and crustal field separately. The normal field provided by the ST model and its “model bias”, which comprise the residuals of the differences between measured and predicted values, are calculated and the respective maps are shown. The residuals are considered an estimate of the local crustal field. In the case of global models, we have applied for each of these three methods to calculate the “model bias”: residuals of the differences between observed values and predicted values of the model, residuals of the differences between observed values and core field values of the model, and the average bias for the period 2001-2012. The normal field of the region of Austria provided by each global model is also calculated. Generally, the regional and global models yield relatively similar crustal fields for the Austrian region, especially when the first method is used. The normal fields calculated by them are in good agreement with each other. Each of the global models directly provides the crustal field, and they are compared with the aeromagnetic data provided by aeromagnetic surveys over the Austrian region. The ST model is in better agreement with aeromagnetic data. We have also analyzed the secular variation over the region, which is calculated from the rate of change of normal field given by the ST and global models.
