VG2 JUP LECP CALIBRATED RESAMPLED SCAN AVERAGED 15MIN V1.1

This browse data 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).

Polar Electric Fields Instrument (EFI), Spacecraft Potential and Plasma Density, Burst Resolution

This data consists of the Spacecraft Potential and the Plasma Density, at spacecraft burst resolution, where the Plasma Density is obtained as a function, provided by Dr. Jack Scudder, the PI of the POLAR Hydra investigation. This function was determined by a fit to the POLAR Hydra particle data for 2001/04/01. The relative accuracy of the Plasma Density, estimated from the spacecraft potential on short time scales is ~10-30% depending on plasma conditions. The absolute accuracy is better than a factor of two for densities less than about 20 particles/cm^3. Density values greater than 30 particles/cm^3 are not plotted because they are inaccurate due to the steep slope of the curve of density versus spacecraft potential. If the value of the argument to the function is too large, then the Plasma Density is set to a filler value of 1.0e+20. Also, if the value returned by the function is too large, then the result is not reliable, and therefore the Plasma Density is set to a filler value of 1.0e+20. If the value of the argument to the function is too small, then the Plasma Density is set to a filler value of 1.0e-20. So, a value of the Plasma Density is a filler value if and only if it is either larger than 1.0e+2 (100.0) or smaller than 1.0e-4 (0.0001); otherwise, it is a true value. Note that all values of the Spacecraft Potential are true values. There is no filler.

Polar PWI Key Parameters

This set of key parameters comes from the Polar Plasma Wave Instrument. The data set contains the observed electron, proton, and oxygen cyclotron frequencies, plus the average and peak electric and magnetic fields in 160 frequencies from the two swept frequency receivers (SFRs), at 5-minute resolution. Additional related mode and antenna information is also given, plus spacecraft position in magnetic coordinates, and the variables Epoch (Time standard for CDF) and Time_PB5 (Time standard for ISTP data). The electron, ion and cyclotron frequencies are derived from the following: Fce = 0.028 kHz*B, where B is the magnitude of the ambient magnetic field measured in nT. Fcp = Fce/1837 in kHz. FcO+ = Fcp/16 in kHz. All frequencies in the Key parameters are converted to Hz. Since the SFR frequency steps vary with the mode, the measured SFR frequencies will be mapped to a fixed array of 160 approximately logarithmically spaced frequency values, 32 frequency values for each of the five SFR channels. In the log mode, the 64 frequency steps of the fourth and fifth frequency channels will be mapped to 32 frequency steps each, using geometric averaging. In the linear mode, the 448 linearly spaced frequency steps of the five frequency channels will be mapped to the fixed array of 160 logarithmically spaced frequency values using a windowing technique. The magnetic and electric field values corresponding to each SFR frequency step will be similarly mapped to 160-point fixed arrays corresponding to the mapped frequency array.

BOREAS TF-10 NSA-YJP Tower Flux, Meteorological, and Porometry Data

The BOREAS TF-10 team collected tower flux and meteorological data at two sites, a fen and a young jack pine forest, near Thompson, Manitoba, Canada, as part of BOREAS. A preliminary data set was assembled in August 1993 while field testing the instrument packages, and at both sites data were collected from 15-Aug to 31-Aug. The main experimental period was in 1994, when continuous data were collected from the young jack pine site from 23 May to 20 Sep. Upon examination of the 1994 data set, it became clear that the behavior of the heat, water, and carbon dioxide fluxes throughout the whole growing season was an important scientific question, and that the 1994 data record was not sufficiently long to capture the character of the seasonal behavior of the fluxes. Thus, the young jack pine site was operated from 08-May to 07-Nov in 1996 in order to collect data from spring melt to autumn freeze-up. All variables are presented as 30-minute averages. Supporting data were also collected to describe the surface's state and to provide the information, in association with the flux data, to build SVAT models. For the young jack pine site, these supporting data included stomatal conductance measurements. Note that only YJP data are included in this data set. Please refer to the other TF-10 data set for fen results.

Ulysses Solar Wind Observations Over the Poles of the Sun (SWOOPS) Alpha Particle Distribution Functions, Level H2, 4 min Data

This File contains the Distribution Function of Alpha Particles. DATA REDUCTION: The SWOOPS (Solar Wind Observations Over the Poles of the Sun) Ion Instrument is a Spherical-Section Curved-Plate Electrostatic Analyzer. Particle Arrival Directions are measured in Spacecraft Coordinates of Azimuth (scanned by Spacecraft Rotation) and Elevation (determined by the Detector Number) Angles. The Spacecraft Spin Axis was oriented toward the Earth. The Energy/Charge (E/q) Resolution was about 2.5% while the Azimuth (Phi) and Elevation (Theta) Resolutions were both ~5.6°. A Description of the SWOOPS is given in a Paper by S.J. Bame, D.J. McComas, B.L. Barraclough, J.L. Phillips, K.J. Sofaly, J.C. Chavez, B.E. Goldstein, and R.K. Sakurai, Astronomy and Astrophysics Supplement Series, Ulysses Instruments Special Issue, Vol. 92, No. 2, p.237-265, 1992. The Number of Counts in each E/q-Phi-Theta Bin were examined to determine the Peak of the Proton and Alpha Particle Distribution, respectively, and the Vector Magnetic Field (in Spacecraft Coordinates) was obtained for the Time at which the Peak was measured. A "coarse" Two-Dimensional Matrix was then formed by rotating the Data into a Coordinate System with Axes parallel and perpendicular to the Field Direction. Note that Gyrotropy is assumed in making that Transformation. The Resolution of the Matrix is "coarse" because the Vector Velocity assigned to each Bin was taken to be at the Center of the Bin. In reality, the Counts in each Bin were probably not smoothly distributed in Velocity Space over the Bin, but were weighted toward the Part of the Bin nearest the Center of the Peak of the Velocity Distribution. The "coarse" Distribution would thus yield Values for the Density and Temperature that were higher than the true Values. A Correction for that effect was accomplished by fitting Contours to the coarse Distribution, breaking each Bin or Pixel into Subpixels, and then using the Contours and the calibrated Angular Responses to distribute the Counts among the Subpixels. New Contours were then computed and the Process was continued until it converged. More Details about this Deconvolution of the Angular Data are given in the Appendix of a Paper by Neugebauer, M., et al., "Ion distributions in large magnetic holes in the fast solar wind" J. Geophys. Res., 106, 5635, 2001. This Procedure generated the Matrix of Velocity Distribution Functions of Protons and Alpha Particles parallel and perpendicular to the simultaneously measured Magnetic Field.

VG2 NEP PLS DERIVED RDR ION OUTBND MAGSHTH L-MODE 48SEC V1.0

This data set gives the best available values for ion densities,      temperatures, and velocities near Neptune derived from data      obtained by the Voyager 2 plasma experiment.  All parameters are      obtained by fitting the observed spectra (current as a function      of energy) with Maxwellian plasma distributions, using a non-linear      least squares fitting routine to find the plasma parameters which,      when coupled with the full instrument response, best simulate the      data. The PLS instrument measures energy/charge, so composition is      not uniquely determined but can be deduced in some cases by the      separation of the observed current peaks in energy (assuming the      plasma is co-moving).

BOREAS TGB-03 Dissolved Organic Carbon Data from the NSA

The BOREAS TGB-03 team collected Dissolved Organic Carbon (DOC) data during the summer of 1994 in the Northern Study Area. The purpose of this work was to establish the major sources, sinks and fluxes of dissolved organic carbon (DOC) in the Northern Study Area. Data on DOC concentrations taken from samples representing the major sources and sinks were to be combined with hydrologic measurements (e.g. precipitation, stream flow etc.) to calculate DOC fluxes.

Van Allen Probe A Electric Field and Waves Suite (EFW) Burst Mode 1 (512 Samples/sec) Electric and Magnetic Fields, Waveform, in Spacecraft Spin (UVW) Coordinates, Level 1 (L1), 1.95 ms Data

The EFW Burst Modes provide targeted Measurements over Brief Time Intervals of 3-D Electric Fields, 3-D Wave Magnetic Fields, and Spacecraft Potential. There are two EFW Burst Modes: BURST1 (B1), Medium-Rate 512 samples/s nominal and BURST2 (B2), Higher-Rate, 16384 samples/s nominal. The Burst 1 Mode Data includes three components of the Electric Field (E12_B1, E34_B1, E56_B1), six Components of the Spacecraft-Sensor Potential (V1_B1 through V6_B1), and three Components of the AC Magnetic Field (SCM_U_B1, SCM_V_B1, SCM_W_B1 from the EMFISIS Search Coil Magnetometer). The Burst 2 Mode Data returns a similar Complement of Electric Field (E_12ac_B2, E34ac_B2, E56ac_B2), Search Coil (SCM_B2, SCM_2B2, and SCM_B2 again from the EMFISIS Search Coil Magnetometer) and Single-ended Potential Measurements (V1ac_B1 through V6ac_B2) with the exception that in the Default Mode the Single-ended Potential and Electric Field Signals are AC coupled with a higher Gain. All Quantities are in "uvw" Coordinates where "u" and "v" are the Sensor Coordinates rotating with the Spacecraft and "w" points along the Spacecraft Spin Axis. Burst Waveform CDF Files are available. The three Data Types available are the Electric Field "E" the Searchcoil Magnetic Field "MSC" and Antenna Potential "V". The Suffix on each of these is either "B1" or "B2". B1 or Burst 1 is the Human-in-the-Loop Burst Type, meaning that both Collection and Playback (for arbitrary Lengths of Time) are requested on the Ground. B2 or Burst 2 is automatically telemetered as short Bursts based on an onboard Triggering Algorithm, typically set to trigger on large Amplitude Signals near 1 kHz. Sample Rates for B1 and B2 can and are changed depending on varying Science Goals.
