IAGA Division V

Objectives of IAGA Division V are:

  1. to promote high quality standards in geomagnetic data acquisition, observatory and survey procedures, geomagnetic indices, and data dissemination
  2. to analyse magnetic observation data for the purposes of understanding the various sources of the magnetic field.  Three working groups are active in this respect.

Working Group V-OBS:Geomagnetic Observation

Working group V-OBS coordinates all issues related to the operation of geomagnetic observatories around the world. The WG sets quality standards for measurements and for data processing, and supports observatories in need of modern instrumentation or those in danger of closure. It cooperates with INTERMAGNET and is responsible for the organisation of a Workshop On Geomagnetic Observatory Instruments, Data Acquisition and Processing every two years. The working group maintains a list of observatories operating worldwide.

Working Group V-DAT: Geomagnetic Data and Indices

This working group defines formats for data exchange and sets quality standards for indices of magnetic activity. The latest format for observatory data dissemination is the IAGA2002 format. Numerous indices of magnetic activity exist and new ones are often developed for different scientific purposes. WG V-DAT cooperates with ISGI and is responsible for assessing and recommending new indices for official adoption by IAGA.

Working Group V-MOD : Geomagnetic Field Modeling

The main task of WG V-MOD is to coordinate international scientific efforts to model and understand the internal geomagnetic field. In particular, the WG assesses and adopts a new International Geomagnetic Reference Field (IGRF) every five years, from candidate models submitted by different research groups. A special task group of WG V-MOD members was in charge of coordinating the development of the first World Digital Magnetic Anomaly Map, published in 2007.

Data and model issues

  • License Task Force: The task force to investigate the licensing of geomagnetic data and data products is led by working group V-DAT and chaired by Simon Flower. As for DOI, the concern on license becomes more and more important. Other scientific bodies (ISC-WDS, IUGG-UCDI, CoreTrustSeal, ISC-CODATA, etc) are interested in this issue. The WG V-DAT decided to initiate to work on this topic.
  • DOI Task Force: led by working group V-DAT, Chair: Masahito Nose (14 TF members). The task force is investigating the possibilities of referencing geomagnetic data products by DOI (Digital Object Identifiers). Note that the citation/recognition topic becomes more and more important. The WG V-DAT decided to continue to work on this topic. Joint sessions were held at the 2017 IAGA meeting and at the 2019 IUGG meeting. Another new session is proposed at the IAGA-IASPEI 2021 joint Assembly.
  • The Call for candidates " 13th generation of International Geomagnetic Reference Field" (epoch 2020.0, predictive up to 2025) has been released by an IGRF Task Group of Working Group V-MOD
