Vega 1 solar wind parameters (20-min)

This data set is a 20-min-resolution collection of solar wind plasma parameters from the interplanetary phases of the Soviet Vega 1 mission to Comet Halley. The data consist of proton flow speeds, densities and temperatures determined by fitting counts-vs-energy data measured on the sunward-looking electrostatic analyzer to a convecting Maxwellian. There are actually two sets of parameters, one ("linear") obtained by minimizing the sum of squares of measured and modelled counts and the other ("log") used logs of counts rather than counts themselves. Also included are numbers of energy intervals used in the linear and log determinations less than and greater than the spectral peaks. The data are at 20-min resolution because the during cruise phase only one or two 10-sec spectra were determined every 20 minutes. Further, the data have long gaps between the first and last days of coverage. The major data gaps are +---------------------------------------------------------------+   Vega 1:   Vega 2:    ----------------------------------------------------------------+   85/04/20 - 85/07/23   85/04/16 - 85/07/24     85/12/21 - 86/01/05   85/09/27 - 85/11/27     86/04/29 - 86/08/04   85/12/03 - 86/02/20       86/02/23 - 86/03/06   +----------------------------------------------------------------+ Discussions of this investigation are found in Gringauz et al (Nature, v321, p282, 1986), Galeev et al (JGR, v93, p7527, 1988) and references therein.

BOREAS TGB-07 Rainwater Herbicide and Organochlorine Concentration Data

The BOREAS TGB-07 team measured the concentration and flux of several agricultural pesticides in air and rainwater samples in order to determine the associated yearly deposition rates. This data set contains information on the rainwater concentration of seven herbicides [2,4-dichlorophenoxyacidic_acid (2,4-D), bromoxynil, dicamb, 2-methyl-4-chlorophenoxyacetic acid (MCPA), triallate, trifluralin, and diclop-methyl] known to appear in the atmosphere of the Canadian prairies. Also, the concentration of three herbicides (atrazine, alaclor and metolachlor), two groups of insecticides (lindane and breakdown products and dichlro-diphenyl-trichloroethane (DDT) and breakdown products), and several polychlorinated biphenyls commonly used in the central United States were measured. All of these chemicals are reported, in the literature, to be transported in the atmosphere. Many have been reported to occur in boreal and arctic food chains. The sampling was carried out from June 16 to August 13, 1993 and May 4 to July 20, 1994 at the BOREAS site in the Prince Albert National Park (Waskesiu).

Vega 2 Magnetic Field Data (2.5 min)

2.5-minute averaged magnetic field measurements from Vega 2. During the cruise phase from Earth to Venus (12/84-06/85) both Vega-1 and Vega-2 spacecraft had one-axis orientation, i.e. the spacecraft X axis was maintained sunward-pointing, while the spacecraft Y and Z axes rotated about the X axis. The spin phase of this rotation was not known, therefore the directions of By and Bz components are unknown. Magnetometer data for this period are presented in spacecraft coordinates as Br (directed radially from spacecraft to the Sun), Bysc, Bzsc. From the providers: "It is proposed to use for analysis of the interplanetary magnetic field during this period the Br component and the total B=sqrt(Bxsc^2+Bysc^2+Bzsc^2). Bysc and Bzsc components are included in the data, but keep in mind that the orientation of these axes is unknown. It can be considered as fixed during periods up to a few hours, so the data can be used to look for IMF discontinues and IMF orientation variations." After Venus flybys (June, 11-15, 1985) up to Comet Halley (March, 6 and 9, 1986) and sometimes later Vega-1 and Vega-2 had three-axis stabilized orientations. After-Venus magnetic field data are presented in spacecraft-centered solar ecliptic (SE) coordinate system as Br, Bzse, Byse, B, where Br is directed from the spacecraft to the Sun, Bzse is directed along Bz axes of the Solar Ecliptic system (to ecliptic pole), Byse completes the right handed set and B=sqrt(Br^2+By^2+Bz^2).

BOREAS TGB-12 Soil Carbon Site Information

During 1993 and 1994, the BOReal Ecosystem-Atmosphere Study (BOREAS) Trace Gas and Biogeochemistry team #12 (TGB-12) collected several data sets to support their analysis of soil carbon content in the Northern Study Area (NSA). The primary data set (BOREAS TGB-12 Soil Carbon Data over the NSA) is described in some detail. Other ancillary information was stored and provided in two sets of soil pit description and surface vegetation transect files. In addition, a site description file provides more information on the positioning of the sampling sites. These files contain additional information that complements the data contained in the primary data set.

Van Allen Probe A Electric Fields and Waves (EFW) Burst 2 waveform data in UVW coordinates E, MSC and V

The EFW burst modes provide targeted measurements over brief time intervals of 3-d electric fields, 3-d wave magnetic fields (from the EMFISIS magnetic search coil sensors), and spacecraft potential. BURST1(B1): Medium-Rate (512 samples/s nominal) BURST2(B2): Higher-rate (16384 samples/s nominal) The burst 1 mode 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 from the EMFISIS search coil magnetometer (SCM_U_B1, SCM_V_B1, SCM_W_B1). 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) and single ended measurements (V1ac_B1 through V6ac_B2) with the exception that in the default mode the single ended 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 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, 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 so trigger on large amplitude signals near 1 kHz. Sample rates for B1 and B2 can and are changed depending on varying science goals.

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

This File contains the Distribution Function of Protons. 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.

BOREAS TGB-12 Radon-222 Activity Data over the NSA

The BOREAS TGB-12 team made measurements of soil carbon inventories, carbon concentration in soil gases, and rates of soil respiration at several sites to estimate the rates of carbon accumulation and turnover in each of the major vegetation types. Sampling strategies for soils were designed to take advantage of local fire chronosequences, so that the accumulation of C in regrowing mosses could be determined. All the data are used to (1) calculate the inventory of C and N in moss and mineral soil layers at NSA sites (2) determine the rates of input and turnover (using both accumulation since the last stand-killing fire and radiocarbon data) and (3) link changes in soil respiration rate to shifts in the 14C content of soil CO2 to determine the average 'age' respired CO2. These 222Rn activity data were collected from 15-NOV-1993 to 16-AUG-1994 over the NSA sites.

BOREAS TGB-12 Soil Carbon and Flux Data of NSA-MSA in Raster Format

The BOREAS TGB-12 team made measurements of soil carbon inventories, carbon concentration in soil gases, and rates of soil respiration at several sites. This data set provides: (1) estimates of soil carbon stocks by horizon based on soil survey data and analyses of data from individual soil profiles; (2) estimates of soil carbon fluxes based on stocks, fire history, drainage, and soil C inputs and decomposition constants based on field work using radiocarbon analyses; (3) fire history data estimating age ranges of time since last fire; (4) a raster image and an associated soils table file from which area-weighted maps of soil carbon and fluxes and fire history may be generated. This data set was created from raster files, soil polygon data files, and detailed lab analysis of soils data that were received from Hugo Veldhuis who did the original mapping in the field during 1994. Also used were soils data from Susan Trumbore and Jennifer Harden (BOREAS TGB-12). The binary raster file covers a 733 km^2 area within the NSA-MSA.
