CATALOGUE OF DIGITAL GEOMAGNETIC VARIATION DATA
AT WORLD DATA CENTER A FOR SOLAR-TERRESTRIAL PHYSICS

I, INTRODUCTION
As high speed computers have become more readily available, the number of requests for digital geo-
magnetic variation data has steadily increased. To meet these needs we have endeavored over the past
decade to collect all geomagnetic data available in this form, in addition to those in tabular formats.

This catalogue lists all of the geomagnetic data available on magnetic tape in World Data Center A for
Solar-Terrestrial Physics. Other information of interest is also provided.

II. SOURCES OF DATA

The geomagnetic variation data available on magnetic tape were obtained from many sources and
institutions. They are as follows:

1. Hourly Values
a. Yearbooks, microfilm, bulletins, etc. from the observatories.
b. Magnetic tapes, punched cards, or punched paper tape from the observatories.

c. Means of 2.5 minute values as derived by the National Geophysical and Solar-Terrestrial
Data Center, Environmental Data Service, NOAA.

2. 2.5 Minute Values
a. Digitizing the magnetograms with the aid of automatic or semi-automatic equipment.

b. Converted from data recorded directly on magnetic tape at one-minute (or shorter) inter-
vals.

3.  K-Indices

International Union of Geodesy and Geophysics, International Association of Geomagnetism and
Aeronomy.

4. Kp-Indices
Magnetic tape prepared by the European Space Research Organization from the data supplied by
the Geophysikalisches Institute of the University of Géttingen. These data are included on a
tape containing other solar and geophysical parameters, among them the day of the solar rota-
tion cycle, Ap, Cp, and C9.

5. Dst-Indices
Goddard Space Flight Center, National Aeronautics and Space Administration.

6. AE-Indices

Those listed below were derived from 10 to 11 observatories well spread in longitude.

Hourly AE Jul 1957-Dec 1964 Geophysical Institute, University of Alaska.
2.5 Minute AE Sep 1964-Dec 1965 Goddard Space Flight Center, NASA.
2.5 Minute AE Jan 1966-Dec 1970 National Geophysical and Solar-Terrestrial Data

Center, EDS, NOAA.
7. Kn, Ks, and Km Indices, Faculté des Sciences de Paris, Institut de Physique du Globe.

8. aa Indices, Faculté des Sciences de Paris, Institut de Physique du Globe.

III. OTHER DIGITAL DATA AVAILABLE AT WORLD DATA CENTER A

Within the past few years a number of observatories have begun direct digital recording of magnetic
variations at one minute (or shorter) intervals. Copies of a small number of these recordings have been
furnished to the World Data Centers. Information regarding the observatory-intervals for which these
data are available will be furnished on request.

IV. MAGNETIC INDICES AVAILABLE IN COMPUTER FORMAT

During this century many types of indices have been derived to show magnetic activity. A list of
those available on magnetic tape is as follows:

1. Kk from individual observatories 1969-1972
2. Kp 1932-Present.
3. Dst 1957-Present
4. AE (Hourly-1966 onward based on 10 or 11 observatories) 1957-1970
5. AE (2.5 Minute-1966 onward based on 10 or 11 observatories) 1957-1970
6. aa 1868-1967
7. Kn, Ks, Km 1959-1970

It is planned to continue preparation of the AE hourly and 2.5 minute indices from 1971 onward.

V. COST OF COPYING AND INFORMATION ON ORDERING

The cost of a direct tape-to-tape copy of any of the data listed in this catalogue is $50.00 plus
the cost of a blank tape. However, if specific observatory-intervals of data are required the cost will
depend on the number of magnetic tapes used in abstracting the required data. The data available at the
present time are stored on approximately 130 (2400-foot) tapes. The cost of copying data for specific
observatory-intervals will be furnished on request to the Data Center.

VI. MAP

The observatory names indicated on the map are those used in the catalogue of hourly and 2.5 minute
values. These are not necessarily the preferred names used in the Master Station List of World Data
Center A for Solar-Terrestrial Physics which covers all disciplines at the Data Center. Of course the
amount of digital data available varies observatory to observatory. The details are presented in the
catalogue.

VII. EXPLANATION OF THE CATALOGUE OF HOURLY AND 2.5 MINUTE VALUES

In the following numbered paragraphs are given explanations of the column headings as found in the
actual catalogue presented in Section X.

1. The observatory names are shown in the first column of this catalogue. Other names for an
observatory at this, or a nearby geographic site, are shown in the second column following
these names. A list of alternate observatory names is also given on page 5 in Section IX.

2. A two-or three-letter mnemonic code as adopted by IAGA in its Bulletin 12 (later 32) Series
is shown after each observatory.

3. In most cases the geographic coordinates were furnished by the institutions operating the
observatories. The geomagnetic coordinates are based on the standard centered dipole (78.5°N
and 291.0°E). In most cases where the observatory moved, but the name remained unchanged,
the coordinates are given for the current site.

4. The catalogue shows the observatory-months for which hourly and 2.5 minute magnetic values
are available on magnetic tape. In most cases three elements (D, H, and Z or X, Y, and Z)
are available.

Sample Computations Showing Use of Tabular Bases

D H Z x Y
Tabular Base -006 155 -485 -025 090
Hourly Value -623 -032 -096 26 250
Total Value -7°02.3' 15468 ~48596 ~2474 9250

As shown above, the value of a magnetic element at any particular time is obtained by adding the
signed tabular base to the signed value.

The customary geomagnetic convention is followed: all magnetic values are referred to the north-
seeking end of the compass needle, with X regarded as positive when directed northward, Y as positive
when directed eastward, Z as positive when directed downward, and D as positive when directed eastward.

Where data are digitized in a semi-automatic manner from normal magnetograms, only one sample
should be taken each 2.5 minutes.

When the basic data are obtained from an automatic digital instrument with a very rapid sampling
rate it is recommended that only one sample per minute be preserved for the World Digital Data Centers.

IX. ALTERNATE OBSERVATORY NAMES

VIII. MAGNETIC TAPE FORMATS FOR HOURLY AND 2.5 MINUTE VALUES

The following tape format was adopted by IAGA at the Madrid meeting in 1969:

Position

1-3 Observatory Mnemonic Code, left adjusted.

4-5 Year, last two digits

6-7 Month (01-12)

8 Element (D, H, Z, F or X, Y, Z, F)

9-10 Day (01-31)

11-12 Blanks

13-15 Arbitrary

16 Blank for data since 1900, '8' for data prior to 1900.

17-20 Tabular base, in degrees for D and I, hundreds of gammas for the intensity
elements. The bases are right adjusted and signed if negative. Negative
values are identified with a minus sign either adjacent to the first signifi-
cant digit or in the high-order position of the field (position 17).

NOTE: A blank digit will not appear between a minus sign and the first sig-
nificant digit. For example, a base may appear as -050 or b-50 but not as -b50
(b=blank).

21-116 Twenty-four 4-digit Hourly Values for the day. The values are in tenth-minutes
for D and in gammas for the intensity elements. The first hourly value repre-
sents the mean value between 00h and Olh..... the 24th value represents the mean
value between 23h and 24h. Rules for negative values are the same as those
described for tabular bases. A missing value is identified by a 9999.

117-120 Daily Mean. Rules for negative values are the same as those described for

tabular bases. If any of the hourly values for the day are missing, a 9999
will appear as the mean.

The 26 values in positions 21-120 will have the range -999 to 9998, with 9999 reserved for missing
values. To avoid a 4-digit negative value in positions 21-116, the tabular base will be adjusted for
that day, for example for D, one degree is subtracted from the base and 600 units are added to each of
the hourly values for the day-- for the intensity elements, 500 gammas are subtracted from the base and
500 gammas are added to each of the hourly values for the day.

Each tape block contains 20 records (2400 characters). A standard inter-record gap appears between
tape blocks. When necessary, padded nines are used to complete the last block of data. Two or more
tape marks follow the last block of data.

) The records are sorted according to observatory mnemonic, year, month, element, day (positions 1-
10).

NOTE: The same format is used for 2.5-minutes values, except positions 11-12 contain the hour (00-23),
and the first data value is for 2.5 minutes past the hour. For 2.5 minute values the hourly mean
appears in positions 117-120, if more than 20 2.5 minute values are missing the mean will appear as
"9999",

NOTE: For those unable to use alphabetic identifications or month-day notation, the following is sug-
gested:

a) observatory code... use a 2 or 3 digit code.
b) element... 1=D, 2=F, 3=H, 4=1, 5=X, 6=Y, 7=Z.
c) month-day... leave positions 6-7 and 9-10 blank and place day number in positions 13-15.
