ASTRONOMY — This category includes al l observations of astronomical objects, both outside and within the solar system, made at various wavelengths (i.e., gamma rays through radio waves). Observed objects outside the solar system include stars, nebulae, galaxies, and all other matter. Observed objects within the solar system include zodiacal light sources, meteoroids, asteroids, dust, micrometeorites, and planetary radio emission sources. Other planetary observations (see Planetary Atmospheres, Planetc,logy, or Ionospheric Physics) and solar observations (see Solar Physics) are excluded. Observations of cosmic-ray particles are listed under Particles and Fields. Celestial mechanics measurements are included under Geodesy and Gravimetry. GEODESY AND GRAVIMETRY — This category includes experiments that measure size, shape, mass, coordinates, altitudes, or gravity fields or experiments concerned with the mapping of a body. It includes the mechanics of orbiting artificial and natural bodies. IONOSPHERIC PHYSICS — This category includes observations of the ionosphere, which is defined as that region of a planetary atmosphere which contains a significant number of free thermal electrons on a daily basis and which has a free electron density maximum in the vertical direction. Its upper and lower exients are roughly defined as the areas in which densities approach 10- 4 of the peak values. Included are all in situ and remotely sensed observations of ionospheric charged particles with thermal energies. This category is used for remotely sensed propagation experiments that primarily focus on the ionosphere, including very low frequency (VLF) and extremely low frequency (E r .F) experiments; for other remotely sensed propagation experiments, an appropriate category, such as Particles and Fields, is used. METEOROLOGY — This category includes observations made in the Earth's hydrosphere and atmosphere up to the mesopause or D region. PARTICLES AND FIELDS — The subcategory Particles includes all in situ charged-particle measurements except those of thermal plasma in terrestrial or other planetary ionospheres (see Ionospheric Physics). It includes all neutron measurements and electromagnetic signal propagation experiments designed to measure columnar electron densities (except those in which the most significant portion of th ,.^ free electrons within the column is within an ionosphere). The subcategory Fields includes all in situ measurements of electric and magnetic fields. It includes V!-F and ELF experiments other than those primarily concerned with observing ionospheric properties. It excludes electromagnetic radiation (radio waves through gamma waves) propagating away from remote sources. (In such cases, either Solar Physics or Astronomy is used, as appropriate.) PLANETARY ATMOSPHERES — This category includes all observations of the gaseous envelope above the surface of a planet. For the Earth the lower limit for observations that belong in this category is about 65 km, the height of the mesopause or D region. (For studies below this altitude, Meteorology is used.) The upper limit is defined as the transition level to the lightest gas. This region overlaps the ionosphere for planets which have an ionosphere; however, ionospheric observations are restricted to observations related to the charge aspects of matter, while Planetary Atmospheres relates to the mass aspects of matter (e.g., composition measurements). For cases in which both atmospheric and ionospheric categories appl y , both may be used. PLANETOLOGY — This category includes experiments for the purpose of deriving and analyzing data from the solid or liquid pz.rts (excluding the oceans of the Earth) of any solar system body. Chemical, physical, and geologic studies of properties of gross or small surface features, materials of the surface, ' internal properties, magnetic properties, etc., are included. Gravitational and geodetic experiments are excluded from this category (see Geudesy and Gravimetry). When the primary purpose of the study is to measure the residual effects of some external phenomena (such as meteorite or cosmic-ray impacts), the external phenomena should determine the choice of category. If necessary, the experiment may be assigned to more than one category. SOLAR PHYSICS -- This category includes all solar observations regardless of the wavelength being observed. The -source region considered here extends outward from the Sun to include that area observed with solar coronagraphs (nominally to 10 solar radii). All in situ measurements of electric or magnetic fields and of particles for which the source is believed to be the Sun are considered to fall in the domain of Particles and Fields.

^+ ^k^ ^^ PREFACE

Many individuals have participated in some way toward producing this catalog and deserve recognition for their efforts. I would like to both acknowledge and thank the many spacecraft experimenters and their colleagues who have submitted their documented data. In addition, a number of National Space Science Data Center (NSSDC) personnel have interacted with experimenters in bringing to NSSDC the data announced and have generated the many descriptions in this catalog. Of the present staff, these persons include L. L. Dubach, R. Horowitz, and Capt. J. C. Lease. A great many other NSSDC personnel, too numerous to name, have also been involved in the data and information handling necessary to produce this catalog. Most of these personnel are associated with the Data Center's onsite contractor, PMI Facilities Management Corporation. To all these, my thanks are extended.

The Data Center is continually striving to increase the usefulness of its data holdings, supporting indexes, and documentation. Scientists are invited to submit their space science data and comments to NSSDC. Catalog recipients are urged to inform potential data users of its availability.

The headings list generic characteristics automated information files of NSSDC is concerned of satellites, experiments, and data sets. with data, programs, models, etc., which cannot be conveniently identified by a relationship to one or a limited number of specific spacecraft (NSDF File). The second report concerns data which can conveniently be 2.1.2.1 CONTENTS OF SPACECRAFT ENTRIES related to a satellite (AIM File). Both reports contain information at three levels as shown below to preclude The heading for each spacecraft description contains repetition of information. the following information about the spacecraft: launch Satellite Nonsatellite date, weight in orbit, status of operation, and, for (AIM) (NSDF) LEGEND inoperable or operationally off spacecraft, the date last spacecraft data were recorded or, if available, the date level 1 satellite data type last usable spacecraft data were recorded.

"Data at NSSDC Ready for Distribution" — designates a data set for which cataloging, verification, and documentation are sufficient to provide a comprehensible set of data to satisfy requests.

• "Data in Published Reports" — indicates that either all or a sign , iicant potilan of the data is contained in a published report or journal, or that the only accessiblc source of any reduced data from an experiment is the published document. The publications cited in the brief descriptions for spacecraft, experiment, or data set entries normally are available through scientific libraries or document distribution centers. NSSDC provides copies of publications only if they cannot be obtained through such libraries or centers. These reports or samples of such data are usually available to NSSDC visitors for reference.

0 "Data at NSSDC" — identifies data sets for which documentation and verification activities are in process. These data are usually sufficiently documented and verified to satisfy routine requests.

m ''Data at NSSDC Processing Deferred" — indicates that the verifying, documenting„ or cataloging of the data set is not complete, and that no additional work will be performed unless specifically requested. NSSDC may be able to supply the data from such a data set in a suitable form, depending upon the completeness of the processing and documentation and the particular requirements of the user. The completeness of the data set is indicate-1 in its brief description.

8 "Data Available from Experimenter" -- used for data sets that NSSDC does not plan to acquire and that the experimenter is willing ; :-, m;skc available, usually in limited amounts, to other scientists. These data sets are nat fcasibir ;or staring at NSSDC, either because they are large in volume or because they require equipment to process. Requests for data sets carrying this indicator should be addressed dv:e; i1 ,/ to the experimenter. The experimenter's name and address and the expected date that the data will be ready for processing are given in the brief description of such a data set.

• "Data at Another Center" -- used for data sets stored and distributed by any other data center. Requests for data sets with this indiwor should be made direr .jy to the organization identified in the brief description. Published reports of this type or samples of such data are usually available to NSSDC visitors for reference.

"Data at Another Center at NSSDC can Process" — denotes a data set held by another data center, but to which NSSDC has access for limited processing. Requests for this type of data set should be submitted to NSSDC.

For information on the procedures for ordering data, please refer to section 1.4 of the Introductino.

The remaining column headings are self-explanatory, R = Resolved except for (1) Planet, (2) Region, (3) RES, and (4) *. P = Partially resolved Brief explanations of these columns are: N = Unresolved U = Unknown resolution 1. Planet: The planets are indicated in numerical I order from the Sun. The Sun is designated as zero A given species is considered resolved when a flux (0); numbers 1 through 9 indicate Mercury, Venus, is associated with that species with a probability of { Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and erroneous flux species association of less than 10 i Pluto, respectively. Letter M indicates the Earth's percent. A species is considered unresolved if the Moon. probability of erroneous association is greater than 40 percent.

INDEXES (continued)

3.5 BAR GRAPHS BY PHENOMENON MEASURED

The time periods covered by charged particle and microscopic neutral particle data sets appearing in this catalog are indexed by means of a series of bar graphs generated from the AIM File. The plots allow the space-phenomenon-oriented user to easily identify the data available for a given time interval. Each plot is arranged alphabetically by spacecraft common name versus data times available from any experiment. Users of this section should be aware that these plots represent an incomplete presentation of information coded into keyword strings; these keyword strings are, by themselves, incomplete codifications of information available as brief descriptions in the main body (section 2.3) of this catalog. More complete information from these "phenomena" indexes is shown in outline form in section 3.4. r
