DESCRIPTION OF WORLD DATA CENTERS 

World Data Centers conduct international exchange of geophysical observations in accordance with the principles set forth 

by the International Council of Scientific Unions (ICSU). They were established in 1957 by the International Geophysical Year 

Committee as part of the fundamental international planning for the IGY program to collect data from the numerous and 

widespread IGY observational programs and to make such data readily accessible to interested scientists and scholars for 

an indefinite period of time. WDC-A was established in the USA.; WDC-B in the USSR.; and WDC-C in Western Europe, 

Australia, and Japan. This new system for exchanging geophysical data was found to be very effective, and the operations 

of the World Data Centers were extended by ICSU on a continuing basis to other international programs; the WDC’s were under 

the supervision of the Comite International de Geophysique (CIG) for the period 1960 to 1967 and are now supervised by the 

ICSU Panel on World Data Centres. 

The current plans for continued international exchange of geophysical data through the World Data Centers are set forth 

in the Fourth Consolidated Guide to International Data Exchange through the World Data Centres, issuedJy the ICSU Panel 

on World Data Centres. These plans are broadly similar to those adopted under ICSU auspices for the IGY and subsequent 

international programs. 

Functions and Responsibilities of WDC’s 

The World Data Centers collect data and publications for the following disciplines: Meteorology; Oceanography; Rockets 

and Satellites; Solar-Terrestrial Physics disciplines (Solar and Interplanetary Phenomena, Ionospheric Phenomena, FlareAssociated Events, Geomagnetic Phenomena, Aurora, Cosmic Rays, Airglow); Solid Earth Geophysics disciplines (Seismology, 

Tsunamis, Gravimetry, Earth Tides, Recent Movements of the Earth‘s Crust, Rotation of the Earth, Magnetic Measurements, 

Paleomagnetism and Archeomagnetism, Volcanology, Geothermics), and Marine Geology and Geophysics. In planning for the 

various scientific programs, decisions on data exchange were made by the scientific community through the international 

scientific unions and committees. In each discipline, the specialists themselves determined the nature and form of data exchange, based on their needs as research workers. Thus, the type and amount of data in the WDC’s differ from discipline to 

discipline. 

The objects of establishing several World Data Centers for collecting observational data were: (1) to insure against loss 

of data by the catastrophic destruction of a single center, (2) to meet the geographical convenience of, and provide easy communication for workers in different parts of the world. Each WDC is responsible for: (1) endeavoring to collect a complete set 

of data in the field or discipline for which it is responsible, (2) safe-keeping of the incoming data, (3) correct copying and reproduction of data, maintaining adequate standards of clarity and durability, (4) supplying copies to other WDC’s of data not received 

directly, (5) preparation of catalogs of all data in its charge, and (6) making data in the WDC’s available to the scientific community. The WDC’s conduct their operation at no expense to ICSU or to the ICSU family of unions and committees. 

World Data Center A 

World Data Ce:lter A, for which the National Academy of Sciences through the Geophysics Research Forum (GRF) and its 

Committee on Geophysical Data has overall responsibility, consists of the WDC-A Coordination Office and nine subcenters 

at scientific institutions in various parts of the United States. The GRF periodically reviews the activities of WDC-A and has 

conducted several studies on the effectiveness of the WDC system. As a result of these reviews and studies, some of the 

subcenters of WDC-A have been relocated so that they could more effectively serve the scientific community. The addresses 

of the WDC-A subcenters and Coordination Office are given inside the front cover. 

The data received by WDC-A have been made available to the scientific community in various ways: (1) reports containing 

data and results of experiments have been compiled, published, and widely distributed; (2) synoptic-type data on cards, microfilm, 

or tables are available for use at the subcenters and for loan to scientists; (3) copies of data and reports are provided upon request.

DISCLAIMER 

Mention of a commercial company or product does not constitute an 

endorsement by the NOAA National Geophysical Data Center. Use 

for publicity or advertising purpose of information from this 

publication concerning proprietary products or the test of such 

products is not authorized. 
Since publication of the directory, IIGeomagnetic 

Observatories 1978" [Report SE-21 of World Data Center A 

(WDC-A) for Solid Earth Geophysics, 19791, there have been 

important changes in instrumentation at the observatories, 

particularly in the method of recording. Although the first 

digital recording began in the early 1960's, only the last 

few years have brought a major transformation of the 

network. Today, more than half the world's standard 

observatories have joined the digital group. This change 

must be termed important progress. It is providing the 

geomagnetic research community with high-resolution data, 

computer ready, and usually more quickly. Many studies can 

now be easily made which before were not feasible. 

Considering the intense current interest by the 

research community in digital geomagnetic data, members of 

Division V of the International Association of Geomagnetism 

and Aeronomy (IAGA) saw a need for a Directory of Digital 

Observatories to assist the data user. In September 1984 

the Division first distributed questionnaires (see Appendix 

3) to the world network, requesting details on each 

observatory's system. WDC-A was asked to compile and 

publish the results. Although some of the observatories 

responded slowly, another delaying factor was the difficulty 

of pinning down the facts -- many observatory systems were 

still being developed, and descriptions of the systems kept 

changing; many had only recently procured their instruments 

and had not begun installation. However, because this 

directory probably will be the only source of information on 

the digital observatories for the next few years, we felt 

that, rather than omitting those that were not yet 

recording, it was better to include all observatories with 

digital equipment on hand and to list as many facts as 

possible. Thus, this Directory shows the current situation, 

as near as it could be determined, as of May 1987. 

We have made a primary separation of the observatories 

into two classes. Those that have programs of at least 

monthly absolute observations, and whose data are thus of 

potential use for studies of secular change, are ordinarily 

called "standard observatoriesv1 (Table la) . In this 

Directory we refer to them as ''observatories. Others, 

whose records are useful only for studies of short time 

variations, are referred to as "variation stations1@ (Table 

lb). Instrumentation at the latter is simpler, less costly 

to operate, often temporary, and our list may not be 

complete. 

1 
Sampling rates vary extensively among the 

observatories, but one-minute values appear to have evolved 

as a standard output, replacing the traditional output of 

mean hourly values. Even at those observatories whose 

instruments sample the field more frequently, one-minute 

values are usually computed either as means or as selected 

individual values for distribution to users. 

Missing information in Tables la through 10 indicates 

that the observatory did not supply the information. At the 

time of this publication, however, an observatory's system 

may still not have stabilized. See Appendix 3 for any questions concerning the table contents or table headings. 

If we have omitted an observatory, misidentified an 

observatory, or made an error in the description, please 

inform us so that it can be corrected in any future edition 

of this Directory. 

HOW TO OBTAIN DATA 

This Directory is not intended to be a catalog of 

available data. On the contrary, those users accustomed to 

obtaining geomagnetic observatory data directly from the 

WDC's may be disappointed to learn that most of the digital 

data are not in the WDC's. Because of excessive cost and 

cumbersome logistics, no attempt is being made to collect 

all the digital data in the WDC system. Some observatories 

routinely deposit copies in one of the WDC's, but others 

await specific requests. In Table 9, in the columns under 

"High resolution, It we list the observatories that routinely 

deposit their data in the WDC's, the observatories that will 

suppl-y their data to a WDC upon request, and the 

observatories that require a direct request from the data 

user. In the second case, the WDC's will assist in 

obtaining data from the observatories. 

If you want a listing of available data, the latest 

catalog is Report UAG-92, I'Combined International Catalog of 

Geomagnetic Data," published in July 1985 by the National 

Geophysical Data Center, NOAA/NESDIS, 325 Broadway, Boulder, 

Colorado 80303, U.S.A. If you want to know the current 

digital data holdings in the WDC system, or have any 

question about the digital data described herein, please 

write to the above address.

Among the listed variation stations are some names that may 

be recognized as standard observatories (e.g., Alma Ata). These 

observatories are listed as variation stations because base lines 

for the digital equipment are not currently being monitored. 

Two digital systems operate at each of the stations at 

Fort Churchill, Fort Simpson, and Fort Smith. The National Research Council of Canada operates one set at Churchill (Fort 

Churchill), Fort Simpson, and Fort Smith as part of the 13- 

station MARIA network. The State University of New York (SUNY) 

operates another set at Fort Simpson and Fort Smith as part of 

their 4-station network.

La Cour magnetograms were used for hourly values until December 

1983. Digitizing was manual on a table and sufficient points were 

selected to define the trace (including all turning points), more 

points for a more disturbed trace. The digitizing has now ceased. 

For the digital system, the IGS fluxgate-logger system is used. 

Up to December 1983 the data (cassettes) are kept, but have not 

been processed. From January 1984 the digital system will be used 

for hourly values.

Manhay 

Trials have been made of an automatic device for digitizing 

magnetogrants. It is based on the use of a video-camera connected 

to a mass-memory and then to an IBM 4341 computer. Complex 

SoftIdare has been developed to determine the equations Of the base 

lines, time lines and to obtain the coordinates of the records of 

D8 H, and 2. The method seems satisfactory, and it may work 

routinely in a feu months. he reliable interval of digitization 

would be about 3 to 5 minutes.
