PREFACE 

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 <CSAGI) as part of the fundamental international 

planning for the IGY program to col teet 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. Woe-A was established in the U.S.A.; Woe-s, in the U.s.s.R.; and woe-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 ce·nters were extended by ICSU on a continuing basis to other international programs; the Woe'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 Con so I f dated GuIde to I nternatl on a I Data Exchange through the Wor I d 

Data Centres", issued by the ICSU Panel on World Data Centres, June 1979. These plans are broadly similar to those adopted under ICSU auspices for the IGY and IQSY. ICSU-sponsored exchange visits have taken 

place between the woe-A (Boulder) and woe-B (Moscow> working staff for the overal I purpose of improving 

data exchange between These centers. One goal was the creation of common formats for computer inventories and catalog publications. By joint agreement the first discipline for this effort was the col lection of geomagnetic data. While this joint effort was developing, woe-c2 for Geomagnetism (Kyoto) 

published a computer based catalog of their geomagnetic holdings •. A digital tape of this catalog was 

shared with woe-A. After reformatting, this information was added to the joint catalog of holdings at 

Woe-A and Woe-82. 

Functions and Responsibilities of WDC's 

The World Data Centers collect data and publications for the following disciplines: Glaciology; 

Meteorology; Oceanography; Rockets and Satellites; Solar-Terrestrial Physics disciplines (Solar and 

Interplanetary Phenomena, Ionospheric Phenomena, Flare Associated Events and 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 Woe's differ from discipline to discipline. 

The objectives of establishing several World Data Centers for col lectlng 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 woe ts responsible for: (1) endeavoring to collect a complete set of data in the field or discipi ine for which it is responsible; (2) safekeeping of the incoming data; (3) correct copying and reproduction of data, maintaining adequate standards of clarity and durability; <4> supplying copies to other 

Woe's; (5) preparation of catalogs of alI data in its charge; and (6) making data in the Woe's available 

to the scientific community. Operating expenses for the Woe's are met by the sponsoring national institution in each host country. 

World Data Center A 

The u.s. National Academy of Sciences has overal I responsibil tty for World Data Center A through the 

Geophysics Research Board and its Committee on Geophysical Data. woe-A consists of a Coordination Office 

at the NAS and discipline centers at scientific institutions in various parts of the United States. The 

GRB periodically reviews the activities of woe-A and has conducted several studies on the effectiveness 

of the woe system. As a result of these reviews and studies some of the centers have been relocated so 

that they could more effectively serve the scientific community. The addresses of the woe-A centers and 

Coordination Office are given inside the front cover. For some data bases the responsibility is not 

simply based on discipline but may also reflect whether the data are collected on an experimental basis 

or synoptic monitoring purposes and the differing responsibilities of the sponsoring host institutions. 

For example, there are very close connections between woe-A for Solar-Terrestrial Physics and woe-A for 

Rockets and Satellites, which exchange solar-terrestrial geophysical data; if it is more convenient, data 

or requests may be sent to one woe-A center through another.

1. Introduction 

In this catalog we have attempted to consolidate, for the first time, alI the geomagnetic data 

from standard, rapid-run, and digital measurements known to exist at World Data Center A for Solar Terrestrial Physics, WDC-B2 and woe-C2 (Geomagnetism). These holdings Include data recorded before the 

IGY when the WDC system was established. Section II of this catalog lists the variety of geomagnetic 

data and products available from WDC-A for STP. 

These geomagnetic data are held In the form of microfilm, magnetic tapes, yearbooks, and bulletins. 

They are In a variety of formats Including magnetograms (normal, storm, and rapid-run), hourly values, 

2.5-mlnute, 1-mlnute, and 10-second values, and various derived Indices for Individual observatories and 

global networks. Data from about 400 observatory locations are referenced in this catalog. Section I II, 

beginning on page 3, lists alI observatories with their international 3-letter code, geographic, and 

geomagnetic coordinates. They are given first In alphabetical order and then sorted according to Increasing geomagnetic co-latitude (dipole co-latitude>. Often observatories are cal led by more than one 

name and where alternate names are known, these also are listed In Section 111. Where one observatory has been replaced by another, often after a time of concurrent operation, these pairs of specially 

related sites are listed here. 

Section IV Is a map showing the location of alI observatories listed In this catalog regardless of 

whether a station Is either or open or closed. Examples of geomagnetic data are shown In Section V to 

II lustrate the variety available. 

The main body of the catalog Is Section VI, beginning on page 41. This detailed listing for each 

observatory gives the years and months for which the woes retain digital data, magnetograms, or K Indices for that site. This Information Is also available on a standard magnetic tape In a common format 

adopted jointly by WDC-A for STP and WDC-B2. 

Section VI I lists stations, codes, and dates for which there are holdings of high resolution geomag- netic digital data. These data are relatively new at the WDCs, most having come Into existence as part 

of the program of data acquisition for the International Magnetospheric Study CIMS>, 1976-1979. In 

general, where data exist with high time resolution there are also corresponding data averaged over less 

frequent sample times, e.g. 10-sec data also exist as 1-mln and hourly averages. Often summary values 

are plotted by computer on microfilm to provide a convenient means for visual examination of the high resolution data. 

Indices of geomagnetic activity may characterize the range and frequency of field variations at a 

single recording site or as measured by a physically significant array of observatories. Section VI II 

gives details about the availability of the principal derived magnetic activity Indices other than the 

local K Index for each observatory which Is given In Section VI, Table 5. 

These geomagnetic data are available to users without restriction. Some WDCs must either recover 

their cost of data preparation or of reproduction. Inquiries and requests for data should be addressed 

to the nearest appropriate World Data Center. Their addresses are the following:

While data copies are available by mall, working visits to the Data Centers are strongly encouraged. Such visits enable the user to browse through the archives and to have access to alI the facilities of 

the Centers, and It Is usually possible to mlnlmlze copying costs. Copying machines, microfilm readers 

and reader-printers, and calculators are available. Special arrangements may be made for the use of computers and other equipment. Arrangements for visits should be made In advance with the proposed World 

Data Center. 

Data received by woe-A centers are made available to the sclentlflc community In a variety of ways: 

(1) In published reports containing data and results of experiments; (2) In digital form on magnetic 

tapes or disks; and (3) In tables, maps and analaog records on either film or paper. WDC-A publica- tions are exchanged with other Centers and data suppliers and are available on a subscription basis to 

anyone. Observations In other formats are available upon request either In exchange for data of a comparable kind and quantity or for the cost of accessing and reproducing the measurements.

World Data Center B2 

The Academy of Sciences of the U.s.s.R. has overal I responsibility for World Data Center B through 

the Soviet Geophysical Committee. WDC-B consists of two discipline centers: WDC-B1 <Glaciology, Meteorology and Oceanography) and WDC-B2 <Solar-Terrestrial Physics and Solid-Earth Geophysics>. The 

addresses of the WDC-B centers coincide and are given on page 1. The Soviet Geophysical Committee 

periodically reviews the activities of WDC-B and has conducted several studies on the effectiveness of 

the woe system. 

Data received by WDC-B are made available to the scientific community In the same ways as do the 

WDC-A centers--for the cost of accessing and reproducing the observations. 

Catalog of Data 

This catalog covers the data of standard, rapid run and digital measurements, subdiscipline 0.1 

In the ICSU Fourth Consolidated Guide to International Data Exchange through the World Data Centres, 

June 1979. 

All such data that have been received associated with the ground-based monitoring of geomagnetic 

phenomena by standard and rapid-run measurements by WDC-A, WDC-B2 and WDC-C2 in both analog and digital 

form are listed here. This publication supersedes all previous catalogs of these data published by 

woe-A and woe-s.

I 11. Lists of Observatories, Codes and Coordinates 

Four separate lists of geomagnetic observatories are presented In this section as descrlbved below. 

Tables 1 and 2 are the baste lists giving alI observatories ordered alphabetically and by geomagnetic 

co-latitude, respectively. Lists 3 and 4 give Information about alternate observatory names and replacement of one observatory by another. 

The listed observatories are those for which data are held In at least one of the Woes. Their 

names, International 3-letter codes, and geographic coordinates are consistent with those given In the 

IAGA News of December 1979. We have corrected or updated entries where appropriate. Corrections to the 

Information published here should be communicated to any appropriate World Data Center. Proposed new 

entries or other changes to this list should be approved by the appropriate IAGA Working Group or their 

designated agent. 

Three different models were used to calculate the magnetic coordinates from the geographic coordinates for each observatory: dipole, Gustafsson, and Tsyganenko. The geomagnetic dipole coordinates, 

co-latitude 01 and east longitude 0', were defined by Schmidt (1895) In ~Mitteilungen uber elne neue 

Berechnung des Erdmagnetlschen Potentials". For these dipole coordinate calculations, geographic coordinates used for the NOrth Geomagnetic Pble were 11.32° co-latitude and 289.59° east longitude. 

Gustafsson's corrected geomagnetic coordinates were computed according to the method described In "A 

Revised Corrected Geomagnetic Coordinate System," Ark. Geophysics, 5, 595-617, and also given In Klruna 

Geophysical Observatory Report no. 694 <April 1969). lhese coordinates are given for alI observatories 

with geographic latitudes greater than 2° to 16°, depending on longitude. They are not defined for sites 

within a latitude band of varying width near the geomagnetic equator, and observatories In this region 

have no entry In this column In Tables 1 and 2. 

Tsyganenko's corrected geomagnetic coordinates were computed according to the method described In 

Tsyganenko, N.A., "Subroutines and Tables for the Geomagnetic Field Computations," Materials of the 

WDC-B2, Moscow, 1979, and In "Numerical Models of Quiet and Disturbed Geomagnetic Field In the Cislunar 

Part of the Magnetosphere," Annales de Geophyslque, 37, 381-394, 1981. 

These coordinates are not given for alI observatories within +30° to -30° geographic latitudes and they 

have no entry In this column In Tables 1 and 2.

1. Normal Magnetogram 

Analog records of D, Hand Z <or X, Y and Z> at a chart speed of 20 mil llmeters per hour In 

most cases. 

2. Storm Magnetogram 

Analog records of D, Hand Z (or X, Y and Z) similar to normal magnetograms but much less 

sensitive. 

3. Rapid-Run Magnetogram 

Analog records of D, H or Z (or X, Y or Z) at chart speeds ranging from 180 to 260 millimeters per hour. 

4. Table of Magnetic Hourly Values 

Mean hourly values of D, Hand Z (or X, Y and Z) centered on the half-hour In most cases. 

5. Table of Magnetic K-lndices 

Three-hourly, quasi-logarithmic measure of changes In Intensity of the Earth's magnetic field ranging from 0 for the least active to 9 for the most active periods. 

6. Table of Magnetic Q-lndices 

Quarter-hourly range Indices from auroral zone observatories on 0 to 9 scale similar to K. 

7. Computer Listing of Indices on Magnetic Tape 

A sample of a computer listing showing the geomagnetic Indices Kp, Ap, Cp and C9, along with 

solar rotation number and day, sunspot number and 10-cm solar radio noise flux, from a tape 

compiled by the European Space Research Organization. 

8. Common Scale Magnetograms of Geomagnetic Storms 

Magnetograms from selected observatories reduced to a uniform time and sensitivity scale. 

9. Principal Magnetic Storms

VI. CATALOG OF GEOMAGNETIC DATA HELD AT WDC-A, B2 OR C2 (TABLE 5) 

Observatory names, International 3-letter codes, and geographic coordinates are consistent with 

those published In "IAGA News", December 1979. The coordinates are co-latitude and east longitude. Components measured at each observatory are either Declination CD>, Horizontal CH>, and Vertical (Z) or 

Geographic North (X), Geographic East CY>, and Vertical (Z). If local K Indices were available for some 

months of the year, this Is Indicated by the letter "K"· For each type of geomagnetic data, there Is 

shown a symbol Indicating which World Data Center holds the data: A = Woe-A for STP, B = Woe-B2, and 

C.= WDC-c2 (Geomagnetism). The catalog does not contain sufficient detail to Indicate when data are held 

for some months of a year by one woe and for other months of the same year by another woe. 

Normal and rapid run magnetograms are usually archived on 35-mm microfilm but original magnetograms 

may also be retained In the archive. Hourly values "any medium" may Include any or at I of the formats In 

which hourly values are available, e.g. tables on microfilm, tables on paper, published In yearbooks, and 

on magnetic tape. Hourly values "on tape" means specifically that the values exist In computer format on 

digital magnetic tape. High-resolution digital values (2.5-mln or 1.o-mtn) are digital data either pro- duced by digitizing analog magnetograms or originally recorded using digital magnetometer systems. The 

1-mln data are Indicated by an asterisk (*). 

High-resolution geomagnetic data with 10-sec resolution are tabulated In Table 6.

VI 1. CATALOG OF HIGH-RESOLUTION GEOMAGNETIC DIGITAL DATA (TABLE 6) 

High-resolution (10-second> geomagnetic digital data were acquired from a network of sites In North 

and South America, the Caribbean, and Pacific Islands during years of the International Magnetospheric Study (IMS, 1976-1979). After some smoothing and noise removal, 1-mtnute average values were prepared 

and are listed In the main catalog given In Section VI. The sometimes noisy to-sec data from these temporary sites were transmitted via GOES satellite communication platforms to the NOAA!ERL Space Environment 

Laboratory where It was partially smoothed by removal of noise spikes and then used in their forecasting activity. Copies of the ful I resolution tapes were deposited with .WDC-A for STP at the end of each 

month. After the end of the observational phase of the IMS, many of the network stations continued oper- ating through the MAGSAT satellite Interval and a reduced number have continued transmitting data through 

1982. 

Statton names and their International 3-letter codes are given for each hlgh-r~solutlon station. 

Also given are the years and months of data acquisition at each site and the symbol of the woe where the 

data are available. Coordinate listing for these sites may be found In Tables 1 and 2 of Section 111. 

Owing to the quantity of data Involved and the complex encoding algorithm that combined Into each 

record data from each site onto a single record, only copies of the original binary magnetic tapes can be 

provided by Woe-A for STP.

* Beginning with January 1975, WDC-A for STP has computed AE Indices with 1-mlnute resolution but stopped routine Index derivation after completing 1975. WDC-C2 (Geomagnetism) 

In Kyoto, Japan, produced 1-mlnute AE Indices for the IMS years 1978 and 1979.
