1. INTRODUCTION

A survey of ground-based geophysical sensors was conducted in 1969 byWorking Group 3 (Interplanetary Disturbances) of the Inter-Union Commission onSolar-Terrestrial Physics (IUCSTP). The results of this survey indicated thatmost of the researchers in this area desired specific summary information onvarious ground-based detectors and observations in the following order of prefer-ence:

(1) Cosmic-ray detectors(2) Riometers(3) Geomagnetic field detectors and measurements(4) Ionospheric observations(5) Solar observations(6) Auroral observations.As a result of this survey. Panel G (Ground-Based Networks) of Working

Group 3 was requested to compile a comprehensive listing of ground-level cosmic-ray detectors. This completed list includes 319 detectors both presently in opera-tion and those which have ceased operating during the period 1932 through 1971.A summary of the. status and type of detectors included in this catalog is given inTable 1.

2. PROCEDURE

When work on this catalog was started, it was planned to include only detectors

which had been in operation at some period of time since the International Geo-

physical Year (1957) through 1970. Initially, the World Data Centers were con-

sulted; it was found, however, that none of the World Data Centers contained a

complete comprehensive listing of these detectors. Furthermore, they encouraged

and supported this type of survey to update their own records. Accordingly,

questionnaires were distributed to the known principal investigators of all cosmic-

ray detectors, and assistance was requested from many of these for help in

locating missing information.

Owing to the large amount of time and correspondence involved in checking

and re-checking records with the principal investigators and the World Data

Centers, an early completion of this catalog was not possible. As the work pro-

gressed it was found that information on many of the original ionization chambers

in operation prior to IGY was being obtained, and accordingly this listing was ex-

tended backward in time to 1932. Subsequent delays and the changing status of

many detectors in 1970 and 1971 made it advisable to update the entire listingthrough December 31, 1971.

As information on each detector was obtained, it was compiled in a standard-

ized format and returned to the principal investigator for checking and correction.

This process was repeated in January 1972 in an effort to update the entire listing.

This compilation reflects the known status of all cosmic-ray detectors as of

December 31, 1971. Any known or expected changes between January 1 and June 1,

1972 have been given under the comments section of each individual listing.

3. SUMMARY LISTING OF COSMIC-RAY STATIONS

Table 2 is a summary listing of the cosmic-ray stations and detectors de-

tailed in this catalog. This list includes the preferred station name, as specified

by the principal investigator, the geographic coordinates, the altitude in meters,

the vertical cutoff rigidity, and the type and number of detectors at each station

both in operation as of December 1971 and those for which operation has ter-

minated. The vertical cutoff rigidities have all been calculated using the trajectory-

tracing procedure described by Shea et al (1965). To ensure consistency, the

Finch and Leaton (1957) sixth-degree internal geomagnetic field representation.

Epoch 1955. 0, was utilized for these calculations. Since many stations are known

by more than one name. Table 3 lists alternate station names.

4. DESCRIPTION OF DETECTOR LISTINGS

The individual descriptions of the various cosmic-ray detectors have been

divided into two principal groups; those in operation as of December 31, 1971,

given in Appendix A, and those whose operation has been terminated, given in

Appendix B. These groups have been subdivided with respect to the various type

of detectors as follows: IQSY neutron monitors, IGY-type neutron monitors,

muon detectors, underground muon detectors, ionization chambers and miscel-

laneous equipment. During the final revision of this catalog, information was

received on the installation and anticipated operation of muon detectors located

at Dourbes, Belgium and Trivandrum, India. The pertinent information is given

in Appendix C.

Each individual listing contains the preferred station name, alternate names

if any, the geographic coordinates in degrees and minutes if available, otherwise

in decimal degrees, the vertical cutoff rigidity, and the station altitude in meters.

The name and present address of the principal investigator is also given, or,

whenever appropriate, the name and address of a person from whom specific in-

formation can be obtained. For detectors presently in operation, the starting

date is given; for those stations where operation has terminated, the period of

opération is included. For researchers interested in detectors operating for aspecific time period, a calendar of operations is given in Appendix D.

The comments section contains miscellaneous items requested by the principalinvestigator. We have also made an effort to establish, whenever possible, if thedata are deposited in the World Data Centers. Principal investigators are en-couraged to routinely deposit their data into the appropriate data center; researchersare urged to utilize the data centers whenever possible The data centers have aworking arrangement whereby data deposited in one data center will be made avail-able, on request, to the other data centers. When requesting specific detailedinformation from a scientist in the Soviet Union, it is recommended that a copy ofeach individual request be sent to World Data Center B2 in Moscow. The addressesof the World Data Centers where cosmic-ray data are deposited are given inTable 4.

We have also included various publications which contain cosmic-ray datafrom individual stations. World Data Center C2 in Japan has been extremely con-scientious in publishing cosmic-ray data from the world network of neutronmonitors during IGY, IGC and IQSY as well as publishing data for other periodsfrom the various Japanese stations. To avoid repetition, we have often listedthese as the "Japanese Cosmic-Ray Intensity Data Books" with the appropriatebook number and date of publication. A complete listing of these books is givenin Appendix E. Also noted, but not mentioned in any of the individual listings, isa publication by Bachelet et al (1971) which contains daily averages for 65 neutronmonitors from 1957 through 1965.

5. MOBILE SURVEYS

No attempt has been made to catalog the relevant information on the manyvaried mobile surveys. Three principal investigators, however, have specificallyrequested that some information be included about their experiments.

Dr. Horacio S. Ghielmetti has been operating an IGY-type neutron monitor(6 counters) on board a ship in the southern hemisphere primarily between BuenosAires and Antarctica with a normal range in vertical cutoff rigidity of 10. 6 to0. 7 GV. The details and counting rates obtained on the first five voyages aregiven by Ghielmetti (1969). Dr. Ghielmetti's address is given under the listingfor the Buenos Aires operating IQSY neutron monitor (Appendix A).

Prof. Serge A. Korff, whose address is given under the closed College,U.S.A., IGY-type neutron monitor (Appendix B) has conducted a series of airplaneflights with the purpose of determining how the flux of cosmic-ray neutrons in theenergy interval between 1 and 10 MeV varies throughout the atmosphere as afunction of the sunspot cycle. Details of their extended polar flights are given bySandie et al (1965).

Since May 1965 Dr. Robert W. Peterson of the University of California LosAlamos Scientific Laboratory, P.O. Box 1663, Los Alamos, New Mexico,87544, U.S.A., has been flying an IGY-type neutron monitor aboard a jet air-craft on selected flights. To date there have been approximately 30 trips extend-ing from one day to a few weeks duration, and include both latitude and altitudesurveys. A description of some of the cosmic-ray experiments aboard this air-craft is given by Peterson et al (1966).

It is not the intent of this catalog to provide a complete bibliography on variousmobile surveys; a selected set of references, however, is given in Table 5.Principal investigators who conduct various latitude surveys are urged to keepthe World Data Centers informed of their activities so that this information isreadily available upon request.

We have tried to make this comprehensive listing as complete and accurate

as possible. It is recognized that a list of this type is continually in need of up-

dating. Therefore it is requested that the principal investigators carefully check

the information relating to their equipment and notify the World Data Centers of

any corrections to be made in this listing. They are also requested to notify the

World Data Centers, in a timely fashion, of any future changes in the information

contained herein. In this way the data centers can maintain an accurate and up-

dated listing of all cosmic-ray detectors which can be readily available upon

request.

IQSY Neutron Monitors

The following listings contain the pertinent information on the IQSY neutronmonitors in operation on December 31, 1971. The locations of these detectors

are shown in Figure Al.These monitors are the standard "NM-64" design described by Carmichael

(1964) and often referred to as "XX-NM-64" where the XX refers to the numberof tubes in the monitor. Thus a 6-NM-64 monitor would contain 6 tubes. Wehave included the number of tubes in each monitor in the individual listings.

P. O. Box 32Hermanus, Republic of South Africa

Comments:

Effective 10 U. T. on March 9, 1967, the data accumulators are routinelystopped 20 seconds every hour for read-out. This change resulted in a decreaseof 0. 6 + 0. 2% in the observed hourly counts. The published data have not beencorrected for this apparent change in counting rate.

Prof. P. H. Stoker of the University of Potchefstroom has determined the"efficiency factor" of the Hermanus neutron monitor statistically, using the 48-NM-64 super monitor at Deep River as a reference standard. The analysisyielded an efficiency factor of 0. 9904 +_ 0. 0004 for the period April 1967 to May1969, relative to the period February 1965 to February 1967, This efficiencyfactor corresponds to a decrease of 0. 96% +. 0. 04 in the counting rate comparedwith the 0. 5%-0. 6% obtained when only the change in readout time is taken intoaccount. At least part of the discrepancy can be ascribed to instability and driftin the high-voltage power supply during the period covered by the statistical an-alysis.


Data published in the following Hermanus Magnetic Observatory publications:(a) Cosmic Ray Bulletin (monthly); (b) Geophysical Series 1 (September 1, 1964-December 31, 1968); and (c) CSIR Report MAG D (January 1, 1969 to the present).

Section A3

Muon Detectors

The following listings contain the pertinent information on the various muondetectors, not including those operating underground, in operation on December31, 1971. The locations of these detectors are shown in Figure A3. A separatelisting is given for each detector even though there may be more than one detectoroperating at the same location.

There is no standard description for the many muon detectors in existence,and many variations exist. For the IGY there was a standard cubical designdescribed by Elliot (1957). In later years it has been common in many countriesto replace the banks of geiger counters with scintillators, but many individualvariations in design exist ranging from single detectors to the crossed telescopetechnique. A description of the meta-muon detector, sometimes referred to as theX-MT-64 (where X denotes the number of independent sections) is given byCarmichael (1964). Whenever possible a description of the detector or an appropriatereference has been included in the detector listing.

Section B2

Muon Detectors

The following listings contain the pertinent information on the various muon

detectors, not including those operating underground, for which operation has

terminated. The locations of these detectors are shown in Figure B2. A separate

listing is given for each detector even though there may be more than one detectoroperating at the same location.

There is no standard description for the many muon detectors in existance,

and many variations exist. For the IGY there was a standard cubical design

described by Elliot (1957). Whenever possible a description of the detector or

an appropriate reference has been included in the detector listing.

Comments:

It was not possible to obtain any information on the status of this stationbeyond that which is available at the World Data Centers. Since neither WDCAnor WDC-C2 has received any data from the Sofia muon detector since December1958, it was decided to consider that the operation of this detector had ceased.The dates of operation were derived from the data deposited in the data centersfor the following periods:

August1957-August1958December 1958

It is assumed that the altitude of the muon detector was the same as the altitudeof Sofia which is approximately 518 meters.
