Voyager 1 Hourly Averaged Plasma Data

The plasma investigation made use of two Faraday-cup detectors, one pointed along the earth-spacecraft line and one at right angles to this line. The earth-pointing detector determined the macroscopic properties of the plasma ions, obtaining accurate values of their velocity, density, and pressure. Three sequential energy scans were employed with (delta E)/E equal to 20, 7.2, and 1.8%, allowing a coverage from subsonic to highly supersonic flow. The side-looking Faraday cup measured electrons in the energy range from 5 eV to 1 keV. The plasma parameters are obtained by finding the best fit of a convected isotropic Maxwellian distribution to the data. One sigma errors are typically less than 0.5% in the speed and VR, less than 5% for the density and thermal speed, and vary greatly for VT and VN. Sampling times range from 12 to 192 sec., with sampling generally more frequent early in the mission. One hour averages were produced from these samples. The velocity components are given in the RTN coordinate system, where R is radially outward, T is in a plane parallel to the solar equatorial plane and positive in the direction of solar rotation, and N completes a right-handed system.

Voyager 1 Plasma Spectrometer (PLS) VIPER-Fit Plasma Ion Composition near Jupiter, 96 s Data

These Data are from a Re-Analysis of the Voyager Plasma Spectrometer, PLS, Data at Jupiter by the PLS Group at the Laboratory for Atmospheric and Space Physics, LASP, at the University of Colorado. Density, Temperature, and Flow Velocity Fits for total and individual Ions were done using the Voyager Ion PLS Experiment Response, VIPER, Code and Error Analysis as described at http://lasp.colorado.edu/home.mop/missions/voyager/viper/. Fits are determined from processing of the Ion Currents from the A, B, C, and D Cups of the Instrument. As per the Fit Case Variable, one of five different Constraints were used in the VIPER Fits for each 96 s Time Interval: (1) Free Variation of all Parameters (mainly for the cold Ion Torus), (2) Constraint of the Ion Abundances for the five major Species (O+, O++, S+, S++, S+++) to standard Composition as determined from Delamere et al., (2005), (3) fixed Ion Composition and Flow Speed, (4) Cold Blobs in the Plasmasheet where resolved Peaks can be Fit with allowance for some Variance in Composition, (5) Interpolation between Composition of Cold Torus and standard Abundances at 6 RJ from Delamere et al., (2005).

Voyager 1 Plasma Spectrometer (PLS) Faraday Cups A-D High Energy Resolution Current Ion Spectra, M Mode, for Proton Energies from 10 eV to 5950 eV, 96 s Data

These Ion Current Spectra in the Jovian Magnetosphere are from the Plasma Spectrometer (PLS) Instrument on Voyager 1 during March 1979 Flyby of Jupiter. The Instrument has four Faraday Cups A, B, C, and D, the Electron Data come only from Faraday Cup D. The Data are specified in Terms of Current per Faraday Cup in femto-amperes (10^-15 A equals 1 fA) versus Channel Number and Energy (eV). This Data Set is for the PLS M Mode covering Proton (H+ Ion) Energies from 10 eV to 5950 eV at High Energy Resolution in 128 logarithmic Energy Channels. The PLS Instrument samples only one Mode of Electron (E1, E2) or Ion (L, M) Spectra in each Time Interval, so the M Mode Data are not continuous but consecutive with the other Modes in Time.

VG2 JUP LECP CALIBRATED RESAMPLED SECTORED 15MIN V1.1

This data set consists of resampled data from the Low Energy        Charged Particle (LECP) experiment on Voyager 2 while the        spacecraft was in the vicinity of Jupiter. This instrument        measures the intensities of in-situ charged particles (>26 keV        electrons and >30 keV ions) with various levels of        discrimination based on energy, mass species, and angular        arrival direction. A subset of almost 100 LECP channels are        included with this data set. The LECP data are globally        calibrated to the extent possible (see below) and they are        time averaged to about 15 minute time intervals with the exact        beginning and ending times for those intervals matching the        LECP instrumental cycle periods (the angular scanning periods).        The data is in the form of 'rate' data which has not been        converted  to the usual physical units.        Data records for the version 1.1 data set provide all data for a        given channel and time period (8 sectors, plus the average for all        sectors) in a single record.

Canadian Geothermal Data Collection: Deep permafrost temperatures and thickness of permafrost, Version 1

Precision temperature measurements have been made in some 150 deep wells and holes drilled in the course of natural resource exploration in the permafrost regions of Northern Canada. In most cases, holes were logged by lowering a probe containing a regions of Northern Canada. In most cases, holes were logged by lowering a probe containing a thermistor incrementally down the well, in other cases multi-thermistor cables were left in the holes and periodic measurements taken. In the 1990's, a few holes were logged by a automatic quasi- continuous logging system. Most holes were logged annually for 5-10 years after drilling completion, and measured temperatures show the disturbance due to drilling and the gradual recovery to near-undisturbed conditions. Some holes in the collection are of depth less than 125 m. Permafrost thicknesses are estimated at each well or hole from the depth of the 0 degree Celsius isotherm. This data collection provides the highest quality of permafrost temperature and permafrost thickness information available for Northern Canada. Other data are the large number of downhole temperature and permafrost thickness estimates taken during commercial well logging of petroleum exploration wells, and are by nature of lesser quality. These data are not included in this data set, but references to compilations of this data are provided. A short text (2000 words), tables of site locations and permafrost thicknesses with small-scale maps, and an extensive bibliography accompany the data collection. The file structure and contents of each file are well described. The text is sufficient to locate the data of interest, and the file description is adequate for a user to recover the parameters of interest. The data are presented on the CAPS Version 1.0 CD-ROM, June 1998.

SOHO LASCO C2 Polarized Brightness FITS Data

The Polarized Brightness data from the LASCO C2 coronagraph.\n\nLASCO (Large Angle Spectroscopic Coronagraph) is comprised of three nested coronagraphs (C1, C2, and C3) that image the solar corona from 1.1--30 solar radii (C1: 1.1--3; C2: 1.5--6; and C3: 3--30). The inner coronagraph (C1) is a newly developed mirror version of the classic Lyot coronagraph without an external occulter, while the middle coronagraph (C2) and the outer one (C3) are externally occulted. C1 is equipped with a Fabry-Perot interferometer that can take monochromatic images over the whole field of view with a spectral resolution of 0.07 nm. By stepping the bandpass across a spectral line, line profiles and Doppler shifts can be derived from all 1024 x 1024 pixels simultaneously. With an equivalent pixel size of 5.6 arcsec, the spatial resolution of C1 is ~11 arcsec. The resolution is ~23 arcsec for C2, and 112 arcsec for C3. The calculated expected precision of the emission line measurements, for example, of the 637.4 nm Fe X line is 0.05 Km/s at 1.1 solar radii, 1.0 km/s at 2 solar radii, and 8.0 km/s at 3 solar radii, all for a 60 s exposure. All three devices use a 1024 x 1024 pixel CCD. The CCDs are passively cooled to 193 K, but can be heated above ambient temperatures to drive off condensed material. The readout rate is ~21 s for a full image, but any line on the CCD can be accessed within about 60 ms, the unwanted lines being dumped. The electronics box provides overall control, including observation programs and scheduling. An observation program can be scheduled to be run at an absolute time or just next in sequence. It can run for a certain number of iterations, an interval of time, or stop at an absolute time. The observation program tasks included, e.g., taking single images from one of the telescopes, a series of images through the three linear polarizers, and a sequence of images at a series of Fabry-Perot wavelength steps. The image processing tasks are primarily image compression, with seven different techniques being available. On average, the readout time should be ~6 minutes or about 200 images/day. This information is from the paper ``The Large Angle Spectroscopic Coronagraph (LASCO): Visible Light Coronal Imaging and Spectroscopy,'' by G. E. Brueckner et al. (Proceedings of the First SOHO Workshop, ESA SP-348, pp. 27-34, November 1992).
