A Report on Geomagnetic Observatories, 1995 

by 

S. J. McLean, K.D. Meyers, L.D. Morris, W.M. Davis 

Like the phenomena it was established to observe, the global geomagnetic observatory network is in 

a constant state of change. This past year has seen some improvement in this network. Great strides 

have been made in Latin America, where the Second Latin-American School on Geomagnetism, held 

this summer, marked a renewed spirit of cooperation between observatories. Stations previously 

operating under great difficulties and able to report only sporadically, have submitted monthly means 

within 6 months of their observation. India and China announced the opening of several new stations. 

This year also marked the first major distribution of observatory yearbooks by the Chinese State 

Seismological Bureau in several years. 

This report is part of the ongoing effort by the World Data Center-A in Boulder, Colorado, to catalog 

the status of the geomagnetic observatory network. Most of the world’s observatories have been very 

generous in making their data available through the World Data Center system, thereby improving 

access and future availability of the data. Tables 1 and 2 contain information on the current magnetic 

observatory network, based on annual means data received at the WDC-A. Maps 1 and 2 show the 

locations of observatories, color coded by the timeliness of the annual mean data available from the 

WDC-A. Because of the importance of higher resolution observatory data, we have included Table 3 

which shows the availability of digital high-resolution data from the WDC-A for Solar Terrestrial 

Physics. 

Finally, to illustrate the changes in the global network with time, Table 4 and Figure 1 give a historical 

look at magnetic observatories producing annual means from 1818 to the present. Table 4 lists 

observatories by country or region, showing the location and years of annual means data available. 

Figure 1 depicts the changes in the number of magnetic observatories in operation with time. This 

illustration is loosely based on work done by S.R.C. Malin and D. Gubbins, but is created from the 

annual means data available from WDC-A. Information for contacting the observatories is available 

in Appendix 1. Electronic mail addresses are included with each contact where available. Appendix 2 

is a sample station report generated from annual means values archived at the WDC-A. 

Based on available information, there are 205 geomagnetic observatories currently or soon to be in 

operation. Of these observatories, 13 stations are planned in the next year or are currently operating 

but have not yet processed their first year of data. These stations are flagged as new with a code of 

“N”. Of the currently operating observatories for which data are available, 151 are located in the 

Northern Hemisphere and 39 in the Southern Hemisphere. As of the date of publication, 23 observatories 

had reported annual means for 1994 and an additional 82 observatories reported 1993 mean values. In 

addition to the new and operating observatories, several observatories are believed to be operating, 

but their exact status and availability of data are not known. These stations are flagged with a code of 

“U” in the tables. 

1 
Historically, magnetic observatories were established to monitor the secular change of Earth’s magnetic 

field, and this remains one of their most important functions. For the purpose of this report, the term 

“standard geomagnetic observatory” or simply “magnetic observatory” implies an installation that is 

producing data suitable for studies of secular change. This generally involves absolute measurements 

sufficient in number to monitor instrumental drift and the production of annual means. The output 

product of the standard geomagnetic observatory has changed as more observatories operate digital 

magnetometers recording high-resolution data. Analog recording rates are typically 20 mmh, while 

digital rates vary from less than one second to one minute. While the digitally-recorded data are 

considered by many to be the primary record, the analog record can be synthesized from the digital 

recordings if desired. Absolute observations of the field elements provide a baseline for the 

magnetograms and monitor instrument drift. Hourly mean values are averaged for the daily, monthly, 

and annual mean values. The magnetic observatory data are crucial to the studies of secular change, 

investigations into Earth’s interior, and to global modeling efforts. The data cataloged in this report 

were made available to modelers working on the next generation of the IGRF. 

For global modeling of Earth’s magnetic field, probably the greatest weakness in the data base comes 

from the uneven geographical distribution of observatories. Observatories are currently limited to 

land areas. The distribution of available land mass and the distribution of observatories on land is 

uneven. As shown on Maps 1 and 2, the majority of observatories producing annual means as well as 

the majority of current means are located in the Northern Hemisphere. 

This report is published by the WDC-A for SEG because the present status of the geomagnetic 

observatory network is of interest to the research community and to many observatory operators. This 

year for the first time, the contents of the report will also be made available in digital form through the 

World Wide Web (WWW). Some WWW addresses of interest to the community are:

Appendix 3: The World Data Center System 

DESCRIPTION OF WORLD DATA CENTERS 

The World Data Centers (WDCs) were created in 1957 to provide archiving for the observational data 

resulting from the International Geophysical Year (IGY). In the years following the IGY, the 

International Council of Scientific Unions (ICSU) recommended that the WDCs continue to collect, 

archive, and redistribute data. This new system for exchanging geophysical data was found to be very 

effective, and the operations of the WDCs were extended by ICSU on a continuing basis to other 

international programs. The WDCs were under the supervision of the Comite International de 

Geophysique for the period 1960 through 1967 and are now supervised by the ICSU Panel on World 

Data Centres. 

World Data Centers have been established in a variety of countries: WDC-A is located in the USA; 

WDC-B in Russia; WDC-C in western Europe, Australia, and Japan; and, WDC-D in the People’s 

Republic of China. The Centers collect and distribute data for a number of disciplines: 

c3 meteorology 

0 oceanography 

0 astronomy 

0 rockets and satellites 

0 solar-terrestrial physics: solar and interplanetary phenomena, ionospheric phenomena, flareassociated events, geomagnetic phenomena, aurora, cosmic rays, airglow 

0 nuclear radiation 

glaciology (snow and ice) and geocryology 

c3 marine geology and geophysics: gravity, magnetics, bathymetry, seismic profiles, marine 

sediment, rock analyses 

0 solid earth geology and geophysics: seismology, tsunamis, gravimetry, Earth tides, recent 

movements of Earth’s crust, Earth’s rotation, magnetic measurements, paleomagnetism and 

archaeomagnetism, volcanology, geothermics 

0 renewable resources and environment 

In each discipline, the scientific community determines the nature and form of data exchange, based 

on research needs. Thus, the type and amount of data in the WDCs differ from discipline to discipline. 

However, each WDC is responsible for: 

J collecting data in the field or discipline for which it is responsible 

J protecting the incoming data 

J copying and reproducing data, maintaining adequate standards of clarity and durability 

J supplying copies of data to other WDCs 

J preparing catalogs of data 

J making data available to the scientific community. 

107 
AI1 the Centers are staffed, funded, and maintained exclusively by the countries in which they are 

located. The WDCs catalog the data and make them available to scientists in all countries upon 

written request or personal visit. Minimal charges may be requested to cover costs of processing the 

requested data. 

WORLD DATA CENTER-A 

World Data Center-A was established in the United States under the auspices of the NationalAcademy 

of Sciences. WDC-A is operated with national resources, but follows ICSU guidelines. The National 

Academy of Sciences has overall responsibility through the Geophysics Research Forum and its 

Committee on Geophysical Data. WDC-A consists of a Coordination Office and nine sub-centers at 

scientific institutions in various parts of the United States. Most WDC-A sub-centers are at 

corresponding national data centers, whose large national collections are available through the WDCA sub-centers. 

Organizations wishing to contribute data or establish exchange agreements should contact the 

appropriate World Data Center-A. Contact information begins on page 73. 

WDC-A FOR SOLID EARTH GEOPHYSICS: REPORTS 

World Data Center-A for Solid Earth Geophysics has a variety of reports related to its activities. This 

publication, SE-53,A Report on Geomagnetic Observatories, 1995, is one in a series. For information
