This is a family of data sets containing 1-min resolution ACE magnetic field and plasma parameters, in GSE and GSM coordinates, both at the location of the ACE spacecraft and as propagated to the location (17,0,0) Re, GSE. Magnetic field and plasma data are from the ACE MFI and SWEPAM instruments, respectively. Propagation was done by J. Weygand using software provided by D. Weimer. The software determines normal directions to assumed planar phase fronts using a modified minimum variance analysis of 1-min magnetic field data, and propagates data using these normals and the Wind-observed solar wind flow velocity. Magnetic field data consist of three Cartesian components, while plasma data consist of three Cartesian components of the flow velocity vector plus proton density and temperature. Data are current to within about 8 months. Different subdirectories hold data for unique combinations of field vs. plasma parameters, GSE vs. GSM coordinates, and unpropagated vs. propagated data. See the VMO interface for a more detailed breakout.

The magnetic field files (CRnnnn.FPM) contains magnetic field components converted from the CRRES tri-axial fluxgate magnetometer sensor output. This data set, however, is different from the ones on the Aerospace agency tapes. The experimenter magnetic field files (which had neither the full time resolution nor the magnetic field intensity resolution of the original magnetometer outputs) were converted to field components in magnetometer sensor coordinates using the software and final calibration coefficient files provided by the magnetometer PI (Dr. Howard Singer, SEL). The original magnetic field files for orbits 6-350 were not readilly available, but the converted files were, so for the sake of uniformity, it was decided to provide the converted files instead of the originals. For those who might wish to get back to the original data, the source code (MAGMPC5.FOR) and calibration files (MAGnn.CAL) which were used to generate the .FPM files are provided. The original CR0237.MAG file is available on CD-8 for comparison with any results of an inversion program written by the user. A program which dumps the CRnnnn.FPM files is also provided on CD-35 (FPMTEST.EXE). This program prints out the UT, three magnetic field components in magnetometer coordinates, total B, and the pitch-angle calculated for the MEA (or a user-selected set of direction cosines). The source code, FPMTEST.FOR, is also provided.

This data set includes files from the "Aerospace Agency Tapes" compiled by the Aerospace Corporation for selected experiments from the CRRES raw telemetry data stream provided through three digital processing units (DPUs) supporting Aerospace-related sensors. These sensors are as follows: the Magnetospheric Ion Composition Spectrometer (MICS), Heavy Ion Telescope (HIT), Low Energy Magnetospheric Ion Composition Sensor (LOMICS), the Medium Electrons A spectrometer (MEA), the Electron and Proton Wide-Angle Spectrometer (EPAS), the Relativistic Proton Detector (RPD), the Proton Switches (PS1, PS2), and a 4-band photometer for chemical release measurements. These instruments were turned on during Orbit 6, off at Orbit 365, and on again at Orbit 416 through the end of mission at Orbit 1067. When another complement of instruments called LASSII were periodically turned on for 20-minute or one-hour intervals near perigee for ionospheric measurements, the RADSAT (magnetospheric) complement, including the Aerospace instruments, were turned off. Spacecraft ephemeris, attitude, and magnetic field data are also provided. For each ten-hour orbit of CRRES includes a set of five files is provided from the original Agency tapes: header, ephemeris, attitude, magnetic field, and the Aerospace instrument raw data file. The magnetic field files are not those provided on the original Agency tapes but include field vector components in magnetometer sensor coordinates as computed from software and final calibration coefficients provided by the CRRES magnetometer team. The instrument data are provided at raw telemetry level in complex form, and users are requested to contact the responsible experimenters concerning correct usage. The binary data are encoded 32-bit words for reading on IBM-compatible PC's; byte order may need to be reversed for usage of other systems (e.g., VMS). FORTRAN source codes with PC-executables are provided to extract selected parameters from the spacecraft and instrument file types. References to documentation for the Aerospace instruments are listed in the main readme file.

This PDS-accessible data set contains Cassini magnetic field data at the highest resolution available as of May, 2012. The MAG instrument consists of the fluxgate magnetometer (FGM) and helium magnetometer that is sometimes operated in vector mode (VHM) and sometimes in scalar mode (SHM). The data for any time may be from any one of these (a flag indicates which), althought seems to be mostly from FGM. Time resolution is variable from time to time, ranging at least from 4 vectors/min to 32 vectors/sec. Nominally, FGM transmits 32 vectors/sec, and VHM and SHM 2 and 1 vectors/sec, at normal downlink data rate. Magnetic field Cartesian components are given mostly in RTN coordinates for the Cassini cruise phase (1999-08-16 to 2004-05-14) and in Kronographic coordinates at Saturn (>= 2004-05-14). Spacecraft trajectory data are not included in the data records. These data are expected to be superseded by Version 3 data to be based on an improved calibration.

The Fluxgate Magnetometer (FGM) data products from the Cluster II Rumba spacecraft consist of magnetic field measurements of the Earth's magnetosphere from a few tens of nT in the outer magnetosphere to over 1,000nT at closest approach. Products are provided at three different time resolutions: full resolution, 5 vectors/second resolution and spin resolution. Each calibration file is valid for the period of one orbit defined from perigee to perigee. The full-resolution magnetic field data has no time averaging applied. If the instrument is in normal mode, the data is at approximately 22 Hz resolution. If it is in burst mode, the data is at approximately 67 Hz resolution. The second product is averaged to a time resolution of 5 vectors per second. The third product is averaged over one spacecraft spin where the spin phase for averaging is the same as that used for the Prime Parameter data. Each of the three primary data products contain the following: time, magnetic field vector, magnetic field magnitude, spacecraft position, instrument range, and telementary mode. The magnetic field components and the spacecraft position are in the GSE coordinate system. In addition to the three primary products, there are five support data products: caveats, calibration field accuracy, calibration files, data missing from processed data set, and data removed by validation process. Caveat files are produced when the calibration is known to be changing on short timescales near eclipses and for other events when visible effects have been observed in the data. Calibration accuracy files contain detailed information on the accuracy of the magnetic field data products and can be used to select periods of data. Calibration files contain the nine elements of the 3x3 calibration matrix and the three offsets for each instrument range. Each file is valid for the period of one orbit for which magnetic field data products have been submitted to the Cluster Active Archive. Data gaps are listed for times at the processing stage when no data were taken, or at the data validation stage where invalid data have been removed. For more details, see "The Cluster Active Archive: Studying the Earth's Space Plasma Environment", edited by Dr. Harri Laakso, Matthew G. T. T. Taylor, C.

Magnetic field and electric field data products from the Cluster Spatio-Temporal Analysis of Field Fluctuations (STAFF) available from the Cluster Active Archive include: Level 2 calibrated data -- STAFF Waveform Analyzer (STAFF-SC) Complex Spectra of the magnetic field in GSE coordinates (normal mode, up to 12.5 Hz and burst mode up to 225 Hz) with a time resolution of 10 second and a frequency resolution of 0.1 Hz; STAFF-SC Calibrated Magnetic Field WaveForm in ISR2 coordinates (normal mode, 25 Hz sampling and burst mode, 450 Hz sampling); STAFF Spectrum Analyzer (STAFF-SA) Spectral Matrix (8 Hz to 4 KHz) which is the cross-product of the magnetic and electric fileds values computed on-board the spacecraft with time resolutions of 4 seconds and 1 second; and Power Spectral Density (8 Hz to 4 KHz) with time resolutions of 1, 0.125 and 0.25 second. Level 3 value-added products include STAFF-SA Polarization and Propagation Parameters (8 Hz to 4 KHz). In the base mode in normal bit rate the auto-spectra are averaged over 1 s, and the complete 25-component matrix is averaged over 4 s for five components. In high bit rate, only the two highest frequency bands are analyzed. In the fast modes, time resolution is 1 s for the cross-spectra, and either 0.125 s or 0.25 s for the auto-spectra. The physical units for magnetic field spectral power are nT^2 Hz^-1, and electric field spectral power, V^2 m^-2 Hz^-1. Ancillary data included preliminary spectra, uncalibrated waveform, caveats, and calibration information.

The Cluster Wide Band Data (WBD) products at the Cluster Active Archive include full time resolution calibrated waveform data obtained in one of three frequency bandwidths: 9.5 kHz, 19 kHz, or 77 kHz in the range of 0-577 KHz along one axis using either an electric field antenna or a magnetic search coil sensor. The dataset also includes instrument mode, data quality and the angles required to orient the measurement with respect to the magnetic field and to the GSE coordinate system. Calibrated electric field data are divided by 1000 to get V m^-1. Because of the high sampling rate of the WBD data (27.4 to 219.5 kilosamples per second), the time resolution of the WBD data (~36 to 5 microseconds in the time domain) is very high. This results in a very large data volume. Because of this the WBD data are stored in CEF files (and in CDF files from which the CEF files were generated) with maximum length of 10 minutes and size of a few hundred Mbytes. The user of WBD data is thus cautioned to take this into consideration when requesting WBD data downloads from the CAA. The 10 minute CDF files can also be downloaded from NASA's CDAWeb.

The following description applies to the Wideband Data (WBD) Plasma Wave Receivers on all four Cluster satellites, each satellite being uniquely identified by its number (1 through 4) or its given name (Rumba, Salsa, Samba, Tango, respectively). High time resolution calibrated waveform data sampled in one of 3 frequency bands in the range 0-577 kHz along one axis using either an electric field antenna or a magnetic search coil sensor. The dataset also includes instrument mode, data quality and the angles required to orient the measurement with respect to the magnetic field and to the GSE coordinate system. The AC electric field data are obtained by using one of the two 88m spin plane electric field antennas of the EFW (Electric Fields and Waves) instrument as a sensor. The AC magnetic field data are obtained by using one of the two search coil magnetometers (one in the spin plane, the other along the spin axis) of the STAFF (Spatio-Temporal Analysis of Field Fluctuations) instrument as a sensor. The WBD data are obtained in one of three filter bandwidth modes: (1) 9.5 kHz, (2) 19 kHz, or (3) 77 kHz. The minimum frequency of each of these three frequency bands can be shifted up (converted) from the default 0 kHz base frequency by 125.454, 250.908 or 501.816 kHz. The time resolution of the data shown in the plots is determined from the WBD instrument mode. The highest time resolution data (generally the 77 kHz bandwidth mode) are sampled at 4.6 microseconds in the time domain (~4.7 milliseconds in the frequency domain using a standard 1024 point FFT). The lowest time resolution data (generally the 9.5 kHz bandwidth mode) are sampled at 36.5 microseconds in the time domain (~37.3 milliseconds in the frequency domain using a standard 1024 point FFT). The availability of these files depends on times of DSN and Panska Ves ground station telemetry downlinks. A list of the status of the WBD instrument on each spacecraft, the telemetry time spans, operating modes and other details are available under Science Data Availability on the University of Iowa Cluster WBD web site at http://www- pw.physics.uiowa.edu/cluster/ and through the documentation section of the Cluster Active Archive (CAA) (http://caa.estec.esa.int/caa). Details on Cluster WBD Interpretation Issues and Caveats can be found at http://www- pw.physics.uiowa.edu/cluster/ by clicking on the links next to the Caution symbol in the listing on the left side of the web site. These documents are also available from the Documentation section of the CAA website. For further details on the Cluster WBD data products see Pickett, J.S., et al., "Cluster Wideband Data Products in the Cluster Active Archive" in _The Cluster Active Archive_, 2010, Springer-Verlag, pp 169-183, and the Cluster WBD User Guide archived at the CAA website in the Documentation section. ... CALIBRATION: ... The procedure used in computing the calibrated Electric Field and Magnetic Field values found in this file can be obtained from the Cluster WBD Calibration Report archived at the CAA website in the Documentation section. Because the calibration was applied in the time domain using simple equations the raw counts actually measured by the WBD instrument can be obtained by using these equations and solving for 'Raw Counts', keeping in mind that this number is an Integer ranging from 0 to 255. Since DC offset is a real number, the resultant when solving for raw counts will need to be converted to the nearest whole number. A sample IDL routine for reverse calibrating to obtain 'Raw Counts' is provided in the WBD Calibration Report archived at the CAA. ... CONVERSION TO FREQUENCY DOMAIN: ... In order to convert the WBD data to the frequency domain via an FFT, the following steps need to be carried out: 1) If Electric Field, first divide calibrated data values by 1000 to get V/m; 2) Apply window of preference, if any (such as Hann, etc.); 3) Divide data values by sqrt(2) to get back to the rms domain; 4) perform FFT (see Bandwidth variable notes for non-continuous modes and/or the WBD User Guide archived at the CAA); 5) divide by the noise bandwidth, which is equal to the sampling frequency divided by the FFT size (see table below for appropriate sampling frequency); 6) multiply by the appropriate constant for the window used, if any. These steps are more fully explained in the WBD Calibration Report archived at the CAA.... +--------------------------+ | Bandwidth | Sample Rate | |-----------|--------------| | 9.5 kHz | 27.443 kHz | | 19 kHz | 54.886 kHz | | 77 kHz | 219.544 kHz | +--------------------------+ COORDINATE SYSTEM USED: ... One axis measurements made in the Antenna Coordinate System, i.e., if electric field measurement, it will either be Ey or Ez, both of which are in the spin plane of the spacecraft, and if magnetic field measurement, it will either be Bx, along the spin axis, or By, in spin plane. The user of WBD data should refer to the WBD User Guide, archived at the CAA, Section 5.4.1 and Figure 5.3 for a description of the three orientation angles provided in these files. Since WBD measurements are made along one axis only, these three angles provide the only means for orienting the WBD measurements with respect to a geocentric coordinate system and to the magnetic field direction ...

The Fluxgate Magnetometer (FGM) data products from the Cluster II Salsa spacecraft consist of magnetic field measurements of the Earth's magnetosphere from a few tens of nT in the outer magnetosphere to over 1,000nT at closest approach. Products are provided at three different time resolutions: full resolution, 5 vectors/second resolution and spin resolution. Each calibration file is valid for the period of one orbit defined from perigee to perigee. The full-resolution magnetic field data has no time averaging applied. If the instrument is in normal mode, the data is at approximately 22 Hz resolution. If it is in burst mode, the data is at approximately 67 Hz resolution. The second product is averaged to a time resolution of 5 vectors per second. The third product is averaged over one spacecraft spin where the spin phase for averaging is the same as that used for the Prime Parameter data. Each of the three primary data products contain the following: time, magnetic field vector, magnetic field magnitude, spacecraft position, instrument range, and telementary mode. The magnetic field components and the spacecraft position are in the GSE coordinate system. In addition to the three primary products, there are five support data products: caveats, calibration field accuracy, calibration files, data missing from processed data set, and data removed by validation process. Caveat files are produced when the calibration is known to be changing on short timescales near eclipses and for other events when visible effects have been observed in the data. Calibration accuracy files contain detailed information on the accuracy of the magnetic field data products and can be used to select periods of data. Calibration files contain the nine elements of the 3x3 calibration matrix and the three offsets for each instrument range. Each file is valid for the period of one orbit for which magnetic field data products have been submitted to the Cluster Active Archive. Data gaps are listed for times at the processing stage when no data were taken, or at the data validation stage where invalid data have been removed.

Level 3 value-added products include STAFF-SA Polarization and Propagation Parameters (8 Hz to 4 KHz). In the base mode in normal bit rate the auto-spectra are averaged over 1 s, and the complete 25-component matrix is averaged over 4 s for five components. In high bit rate, only the two highest frequency bands are analyzed. In the fast modes, time resolution is 1 s for the cross-spectra, and either 0.125 s or 0.25 s for the auto-spectra. The physical units for magnetic field spectral power are nT^2 Hz^-1, and electric field spectral power, V^2 m^-2 Hz^-1. Ancillary data included preliminary spectra, uncalibrated waveform, caveats, and calibration information.
