THEMIS-B: On Board moments: ESA and SST Electron/Ion moments, density, flux, velocity, pressure and temperature.

THEMIS-B On Board moments. On board data outputs include number density, particle flux, energy flux, and a six component symetric momentum flux tensor. Other moments are calculated from these partial moments on the ground adding total pressure, velocity, plasma temperature (measured as a three dimensional energy vector), and a six component symetric pressure tensor to the list of data products. Number density and total pressure are scalar outputs. Velocity is calculated in DSL, GSE, GSM, and MFA coordinates (coordinate descriptions are listed below in Table 1). Magnetic Field Aligned pressure tensor and temperature are calculated as well. All quantities are calculated for both ions and electrons from a combination of ESA and SST data. Moments data are taken at spin resolution in all ESA survey modes except burst. The spacecraft potential, as measure by the EFI, is used to correct for spacecraft charging by shifting the particle energies for calculation; this eliminates contamination from photo-electrons. Also, weighting factors are used to account for instrument specific energy and angle efficiency variations. Table 1: Coordinate Descriptions. Despun Sun - L-vector (DSL): Z-axis points towards the spin axis, the Y-axis is obtained from the cross product of Z and the Spacecraft-Sun direction as viewed from the probe. The X-axis sits in the Z-axis-Sun plane and completes a right handed system. Geocentric Solar Ecliptic (GSE): Z-axis is normal to the solar ecliptic, the X-axis points from earth towards the Sun, and Y complets a right handed system. Geocentric solar Magnetosphereic (GSM): X-axis points from Earth to the Sun, the Y-axis is orthogonal to the Earth's magnetic dipole and points towards the dusk side, and the X-Z plane contains the dipole axis. Magnetic Field Aligned (MFA): Z-axis points along magnetic field lines, the Y-axis is the orthonormal cross product of the Z-axis and a vector pointing towards the Sun, and the X-axis completes the right handed system.

Alouette-2 Topside Sounder Average Ionogram over Santiago, Chile: SNT, Latitude -33, Longitude 298

This Ionogram was digitized from the original Alouette 2 Analog Telemetry Data on 7-Track Tape using the Facilities of the Data Evaluation Laboratory at NASA GSFC, Code 500. This Data Restoration Project is headed by Dr. R.F. Benson, NASA GSFC, Code 692. Ionograms were digitized at the Rate of 40,000 16-bit samples/s. This Sample Rate is higher than the Nyquist Frequency of 30 kHz. The Sample Frequency of 40 kHz provides a Measurement every 25 ms corresponding to an Apparent Range Interval of c*t/2, where c is the Speed of Light, or 3.747 km. Each Ionogram consists of a Fixed Frequency Portion and a Swept Frequency Portion. The Time Resolution is typically 31 s.

CLAMS Chesapeake Lighthouse Vaisala RS-80 Radiosonde

CLAMS_CERES_CHESLIGHT_SONDE data were collected during the Chesapeake Lighthouse and Aircraft Measurements for Satellites (CLAMS) experiment.The CLAMS_CERES_CHESLIGHT_SONDE data set was collected by Vaisala RS-80 Radiosonde at the Chesapeake Lighthouse, which is a Coast Guard platform located 25 km East of Virginia (near the mouth of the Chesapeake Bay). It is located outside of the surf zone and far enough away from shore to make it an excellent validation site for space-borne retrievals of cloud and aerosol microphysics. The platform itself is small enough (25x25 meters) that the usual island effect associated with oceanic sites is negligible. Aerosol climatology at this location indicates optical depths and Angstrom exponents that are consistent with polluted urban aerosols, which is not surprising given its close proximity to Virginia Beach and Norfolk, VA. These urban aerosols will also have an impact on the marine clouds at the site. Not all air masses at Chesapeake Lighthouse are polluted, however, as Easterly winds from occasional synoptic systems and frequent sea breezes provide a marine aerosol source. Hence, the Chesapeake Lighthouse is an excellent location to study the impact of anthropogenic aerosols on cloud microphysical properties (i.e., the indirect effect).

THEMIS-A: Probe Electric Field Instrument and Search Coil Magnetometer Instrument, Digital Fields Board - digitally computed Filter Bank spectra and E12 peak and average in HF band (FBK).

The Filter Bank is part of the Digital fields board and provides band-pass filtering for EFI and SCM spectra as well as E12HF peak and average value calculations. The Filter Bank provides band-pass filtering for less computationally and power intensive spectra than the FFT would provide. The process is as follows: Signals are fed to the Filter Bank via a low-pass FIR filter with a cut-off frequency half that of the original signal maximum. The output is passed to the band-pass filters, is differenced from the original signal, then absolute value of the data is taken and averaged. The output from the low-pass filter is also sent to a second FIR filter with 2:1 decimation. This output is then fed back through the system. The process runs through 12 cascades for input at 8,192 samples/s and 13 for input at 16,384 samples/sec (EAC input only), reducing the signal and computing power by a factor 2 at each cascade. At each cascade a set of data is produced at a sampling frequency of 2^n from 2 Hz to the initial sampling frequency (frequency characteristics for each step are shown below in Table 1). The average from the Filter Bank is compressed to 8 bits with a pseudo-logarithmic encoder. The data is stored in sets of six frequency bins at 2.689 kHz, 572 Hz, 144.2 Hz, 36.2 Hz, 9.05 Hz, and 2.26 Hz. The average of the coupled E12HF signal and it's peak value are recorded over 62.5 ms windows (i.e. a 16 Hz sampling rate). Accumulation of values from signal 31.25 ms windows is performed externally. The analog signals fed into the FBK are E12DC and SCM1. Sensor and electronics design provided by UCB (J. W. Bonnell, F. S. Mozer), Digital Fields Board provided by LASP (R. Ergun), Search coil data provided by CETP (A. Roux). Table 1: Frequency Properties.

CASSINI S MIMI INCA SENSOR CALIBRATED DATA V1.0

The Ion and Neutral Camera (INCA) obtains remote images of the global      distribution of energetic ions for energies from 7 keV/nucleon to 8      MeV/nucleon, discriminated according to energy and mass species      (oxygen and hydrogen). To obtain the images, INCA measures the arrival      directions, energy and mass species of Energetic Neutral Atoms (ENA's)      using the relatively new technique of ENA imaging. INCA also can be      commanded to obtain very high sensitivity ion measurements, providing      the angular, energy and species distributions of in-situ O and H ions.      The Cassini Magnetospheric Imaging Instrument(MIMI) Imaging Neutral      Camera (INCA) calibrated data set includes all image data collected      from the MIMI Data Processing Unit during the Saturn tour. The      original data has been decommutated, decoded, calibrated and further      processed by software at the Applied Physics Laboratory (APL).      The calibrated image data is provided in three forms: an averaged      form where the original image N x N pixel images pixels intensity are      averaged to a single value for one species and time-of-flight (TOF)      combination, browse images which display rows and columns of images      for one species and TOF combination, and movies which display      averaged ENA image skymaps.      Calibration of INCA data has been described fully in the      Cassini/MIMI Data User Guide.      This data set should be among the first used by a user of any of the      MIMI INCA archive as it will lead one to information required to      search for more detailed or highly specialized features in the      original data.
