CAMEX-4 DC-8 LIGHTNING INSTRUMENT PACKAGE (LIP) V1

The CAMEX-4 DC-8 Lightning Instrument Package (LIP) dataset was collected by the ER-2 Lightning Instrument Package (LIP), which allows the vector components of the electric field (i.e, Ex, Ey, Ez) to be readily obtained, and thus, greatly improves our knowledge of the electrical structure of storms overflown during the CAMEX-4 campaign. The field mills measure the components of the electric field over a wide dynamic range extending from fair weather electric fields, (i.e., a few to tens of V/m) to larger thunderstorm fields (i.e., tens of kV/m). Total lightning (i.e., cloud-to-ground, intracloud) is identified from the abrupt electric field changes in the data. The conductivity probe measures the air conductivity at the aircraft flight altitude. Storm electric currents can be derived using the electric field and air conductivity measurements.

Helios 1 E6 (Kunow) Hourly Particle Fluxes in CDF Format

particle-flux>Merged proton, electron and alpha particle fluxes. Helios-A and Helios-B Spacecraft were a Pair of Deep Space Probes developed by the Federal Republic of Germany, FRG, in a Cooperative Program with NASA. The Purpose of the Mission was to make pioneering Measurements of the Interplanetary Medium from the Vicinity of the Earth Orbit to 0.3 AU. The Objective of Experiment, E6, was to study High-Energy, Charged, Cosmic Ray Particles of Solar, Planetary, and Galactic Origin in Interplanetary Space. Protons and Alpha Particles with Energies &gt;1.3 MeV/n, and electrons &gt;3.3 MeV were measured within Interplanetary Space over the Range from 0.3 to 1.0 A.U. The Instrument, a Particle Telescope with 55$#176; Field of View, consisted of five Semiconductor Detectors, one Sapphire Cherenkov Counter, and one Scintillation Counter, all enclosed by an Anticoincidence Cylinder. The Telescope was calibrated prior to Launch using Radioactive Sources, Particle Acceletors, and Ground-Level Muons. It measured Protons and Alpha particles in six Channels, 1.3 to 3.3, 3.3 to 13, 13 to 27, 27 to 37, 37 to 45, and &gt;45 MeV/n, and Electrons in five Energy Channels, 0.3 to 0.8, 0.8 to 2, 2 to 3, 3 to 4, and &gt;4 MeV. For more Detail See pages 253-257 of Raumfahrtforschung, Volume 19, Number 5, 1975. The Helios-A Cosmic Ray &apos;.dat&apos; and Helios-B Cosmic Ray &apos;.dat&apos; files contains hourly averaged Fluxes of Electrons, Protons and Alpha Particles in the MeV Ranges. The Files were written in ASCII-Codes. Each Record contains 10 hourly Averages. The Differential Fluxes, (m^2 s sr MeV)^-1, Cover, in several Bands, the Energy Range 0.3 to 2.0 MeV for Electrons, 4.0 to 51 MeV for Protons, and 2.0 to 48 MeV for Alpha Particles. Also provided are the Integral Fluxes of Alphas above 48 MeV, and Protons above 51 MeV. For some of the Energy Channels, the Standard Deviations of the Averages are also provided. Each File is preceded by a Header Record, providing the Start and Stop Times of the Data in the File. The Acronyms for the Rate Channels are composed of a Letter and an Indication of the Energy Range in MeV/n for Protons and Alpha Particles, respectively and MeV for Electrons. The counting Rates are given as (m^2 s sr MeV/n)^-1 except for the Integral Channels P&gt;51 and A&gt;48, which are given as (m^2 s sr)^-1. Note: 1. Negative Rates, -0.99999E+04, indicate Missing or Invalid Data. 2. The Energy Boundaries for the Electron Channels 0.2 to 0.8 and 0.8 to 2 are only rough Estimates.

The CAMEX-4 DC-8 Microwave Temperature Profiler (MTP) dataset was collected by the MTP, which is a passive microwave radiometer used during the CAMEX-4 campaign to collect data measurements of thermal emmission from oxygen molecules in the atmosphere for a selection of elevation angles. Current observing frequencies are 56.6 and 58.8 GHz. Measured brightness temperature versus elevation angle is converted to air temperature versus altitude using a statistical retrieval procedure. An altitude temperature profile is produced every three km along the flight path. These data were collected from August 16 - September 25, 2002 from Jacksonville Naval Air Station, Florida.

CAMEX-4 DC-8 NEVZOROV TOTAL CONDENSED WATER CONTENT SENSOR V1

The CAMEX-4 DC-8 Nevzorov Total Condensed Water Content Sensor dataset was collected by the Nevzorov total condensed water content sensor which was used to measure the total water content of air sampled during the CAMEX-4 campaign. The Nevzorov water vapor probe flew aboard the NASA DC-8 aircraft during CAMEX-4 to study tropical storms and hurricanes. Nevzorov is a so-called hot-wire device, where two resistors are heated to evaporate all hydrometeors that touch their surfaces during the flight. Due to their shape, they are able to catch small droplets or droplets and ice crystals. The amount of energy necessary to evaporate particles is a direct measure of the liquid water content of the hydrometeor (liquid or frozen) and also gives an indication of the water vapor present.

HARDERSEN IRTF ASTEROID NIR REFLECTANCE SPECTRA V1.0

This dataset includes average near-infrared (NIR) reflectance spectra for 68 main-belt asteroids that were observed at the NASA Infrared Telescope Facility (IRTF), Mauna Kea, Hawaii, from April 2001 to January 2015. Raw NIR spectral data were obtained under mostly uniform instrumental conditions and include observations of the asteroids, extinction stars, and solar analog stars that were necessary for data reduction and production of the final average asteroid NIR reflectance spectra. SpecPR and Spextool were used during data reduction to produce the final spectra and both programs utilize similar functions that include sky background subtraction, telluric corrections, channel shifting, and averaging routines. The set of asteroids observed include a wide variety of taxonomic types and include V-, S-, M-, X-types that correspond to a wide variety of surface mineralogies, rock types, and potential meteorite analogs.

PVO VENUS ONMS BROWSE SUPERTHERMAL                                      OXYGEN 12 SECOND V1.0

The instrument has detected superthermal, energeticor fast ions whose energy exceeds 36 eV in the spacecraftframe of reference.  These ions were observed in early orbitsduring measurements of the neutral density near periapsis, havean erratic and unpredictable signature, and occur at too high analtitude to be due to the neutral atmosphere. When the altitudeof periapsis increased above the point where sensible neutraldensity measurements could be made, the instrument was configuredspecifically to detect superthermal ions.  In general, for orbitnumbers 1 to 645, data were taken from the RPA mode.  The gasbackground signal with the filament on is about a factor of 10less in this mode than in non-RPA mode, resulting in a lowerdetection threshold. For orbit numbers above 923, the instrumentwas deliberately configured with the filament off and non-RPAmode data was used. For mass 16 the RPA voltage is about +3.8volts.

CAMEX-4 JPL LASER HYGROMETER V1

The CAMEX-4 JPL Laser Hygrometer dataset contains water vapor volume and mixing ratio concentractions collected during the CAMEX-4 campaign to study tropical cyclones. The Laser Hygrometer measures in situ water vapor content using a tuneable laser emitting at 1.37 microns. Absorption at that wavelength is a function of water vapor content, thus measuring the amount of absorption in an open path beyond the aircraft boundary layer, a value of water vapor pressure is made. The maximum sampling rate is 8 Hz, but the instrument is normally configured through the software for a 1Hz sampling rate.

VEGA1 HALLEY FLYBY MAGNETOMETER DATA

On MARCH 6, 1986, AT 7:20:06 UT, the Vega spacecraft passed the nucleus of comet Halley at a distance of 8,890 km with a relative velocity of 78 km/s. The magnetic field experiments MISCHA carried four fluxgate sensors, with three sensors mounted on a boom at the end of the solar panels and the fourth sensor mounted one meter closer. During the cruise phase, the TRASSA-1 mode of the instrument (1 vector/2.5 min) was used. The sensors were switched to the TRASSA-2 mode (1 vector/min) during the flyby which started roughly two days before the encounter. From 3 h before closest approach (CA) until 1 hour after CA, the HS-mode (1 vector/6s) and the DT-mode (1 vector/100ms) was used [DELVAETAL1991].
