- Testing Geomagnetic Reference Field models for 1990-2000 with data from the Trelew Geomagnetic Observatory, Argentina Marta E. Ghidella Julio C. Gianibelli Jacqueline Köhn Ciencias de la Tierra IGRF secular variation Trelew observatory (Argentina) Every five years a new International Geomagnetic Reference Field (IGRF) model is released and the secular variation forthe previous period is updated, producing the definitive DGRF model. Once a DGRF is released, the previously calculated magneticanomalies are updated. We show the importance of this correction for the 1995-2000 period, in which the DGRF-IGRFdifference is anomalously large. We document the validity of the correction by using data from the permanent geomagneticObservatory of Trelew, Argentina. 2003 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56842406 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.4 Vol.42
