MARS GLOBAL SURVEYOR RAW  DATA SET - MAP V1.0

This data set contains archival raw, partially processed, and  ancillary/supporting radio science data acquired during the  Mapping (MAP) phase of the Mars Global Surveyor (MGS)  mission. The radio observations were carried out using the MGS  spacecraft and Earth-based receiving stations of the NASA Deep  Space Network (DSN). The observations were designed to test  the spacecraft radio system, the DSN ground system, and MGS  operations procedures; to be used in generating high-resolution  gravity field models of Mars; and for estimating density and  structure of the Mars atmosphere. A small number of surface  scattering experiments were also conducted. Of most interest  are likely to be the Orbit Data File and Original Data Record  files, in the ODF and ODR directories, respectively, which  provided the raw input to gravity and atmospheric  investigations. The MAP phase extended from March 1999 through  January 2001. Data were organized in approximately  chronological order and delivered on a set of 184 CD volumes at  the rate of 2-3 CD's per week. Typical volume of a one-day ODF  was 300-400 kB. Typical volume of an ODR was 5-10 MB, and there  were typically 8-16 ODR's per day depending on DSN schedules and  observing geometry.

VG2 NEP PLS DERIVED RDR ION MAGNETOSPHERE 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).

ISEE 3 Vector Helium Magnetometer (MAG), Magnetic Field, 1 min CDF Data

This Data Set contains averaged 1 min magnetic field data converted from simple ASCII records. It was created at the NSSDC from a more complex, multi-resolution data set with the current NSSDC ID of SPHE-00673 and old NSSDC ID of 78-079A-02D, provided by the Principal Investigator Team and now available from ftps://spdf.gsfc.nasa.gov/pub/data/isee/isee3/magnetic_fields/1min_ascii_extracted/. The Coordinate System for the magnetic field components is the JPL-defined I,S Coordinate System set at the origin at the spacecraft: I is the unit vector in the direction of the ISEE 3 spin axis, positive in the northward direction, and S is the unit vector from the spacecraft to the sun. The Z-Axis is parallel to I, the Y-Axis is parallel to the cross product I ⨯ S, and the X-Axis is parallel to Y ⨯ Z. The I,S coordinate system is approximately the same as the Solar Ecliptic, SE, System since the Spacecraft Z-Axis, the Spin Axis, is maintained within 0.5° of perpendicular to the Ecliptic Plane. The SE coordinate system is defined in the same way as GSE, but with the spacecraft point of observation substituted for the position of the earth. For years 1984 through 1990 the spacecraft position in HGI coordinates was added to the data product. The HGI coordinate system is sun-centered and inertially fixed with respect to an X-Axis directed along the intersection line of the Ecliptic and Solar Equatorial planes, which defines the 0° longitude direction. The Solar Equatorial plane is inclined at 7.25° from the Ecliptic. This direction was towards an Ecliptic longitude equal to 74.367° on January 1, 1900 at 12:00 UT, but because of the precession of the earth's equator, this longitude increases by 1.4° per century. The Z-Axis is directed perpendicular to and northward of the solar equator and the Y-Axis completes the right-handed Set. The HGI longitude increase from 0° in the X-Direction towards the positive Y-Direction. The HGI latitude increases to +90° at the north pole and decreases to -90° at the south pole. Note that the values listed are 1 min averages, so that  B ^2 may not equal  B^2 .

AIRS/Aqua L3 Monthly Quantization in Physical Units (AIRS-only) 5 degrees x 5 degrees V006 (AIRS3QPM) at GES DISC

The Atmospheric Infrared Sounder (AIRS) is a grating spectrometer (R = 1200) aboard the second Earth Observing System (EOS) polar-orbiting platform, EOS Aqua. In combination with the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil (HSB), AIRS constitutes an innovative atmospheric sounding group of visible, infrared, and microwave sensors. AIRS/Aqua Level 3 monthly quantization product is in physical units (AIRS Only). The quantization products (QP) are distributional summaries derived from the Level-2 standard retrieval products (of swath type) to provide a more comprehensive set of statistical summaries than the traditional means and standard deviation. The QP products combine the Level 2 standard data parameters over grid cells of 5 x 5 deg spatial extent for temporal periods of a month. They preserve the multivariate distributional features of the original data and so provide a compressed data set that more accurately describes the disparate atmospheric states that is in the original Level-2 swath data set. The geophysical parameters are: Air Temperature and Water Vapor profiles (11 levels/layers), Cloud fraction (vertical distribution).

ISEE 3 Ephemeris, Heliocentric Trajectories, Heliographic, Heliographic Inertial, and Solar Ecliptic Coordinates, HelioWeb, Daily Data

Heliocentric trajectories for ISEE 3 in Heliographic, HG, Heliographic Inertial, HGI, and Solar Ecliptic, SE, Coordinates\n\nThe original trajectory data are taken from http://ssd.jpl.nasa.gov/horizons.cgi where users can find many more objects. In the case of orbit data for planets, the orbit data can be used as a proxy for spacecraft ephemeris that are in orbit about the planets. On a heliospheric scale, differences between the planet orbital tarjectory and that of the spacecraft are very small. For instance, the heliocentric longitudes differ by only 0.25° for a spacecraft stationed near the L1 Lagrange point at approximately 100 Earth radii upstream of the Earth.\n\nThe production of the HG, HGI, and SE trajectory data requires a values for the "Equinox Epoch", which is defined as the epoch time when the direction from the Earth to the sun at the time of the vernal equinox when the sun seems to cross equatorial plane of the Earth from below. This direction is called the First Point of Aries, FPA and it is not a fixed direction but drifts by about 1.4° per century or 50.26" per year. In addition, there are tiny irregularities in FPA drift that are on the order of 1" per year or less. The Equinox Epoch can be determined by using a variety of methods for calculating the instantaneous FPA longitudinal direction and whether the tiny irregularities have been smoothed or averaged out. Four methods for determining the Equinox Epoch are in common usage:\n\n+---------------------------------------------------------------------+\n| Method Name  | FPA Longitude Definition                             |\n|---------------------------------------------------------------------|\n| B1950.0      | the actual FPA at 22:09 UT on December 31, 1949      |\n| J2000.0      | the smoothed FPA at 12:00 UT on January 1, 2000      |\n| True of Date | the actual FPA at 00:00 UT on the date of interest   |\n| Mean of Date | the smoothed FPA at 00:00 UT on the date of interest |\n+---------------------------------------------------------------------+\n\nThe heliocentric trajectory data included in this data product have been calculated by using the Equinox Epoch: defined via the "Mean of Date" method.\n\nMore precise coordinates, and some planet-centered coordinates, are found in the "traj" subdirectories of spacecraft specific directories at https://spdf.gsfc.nasa.gov/pub/data/ and http://ssd.jpl.nasa.gov/horizons.cgi.

AIRS/Aqua L3 Monthly CO2 in the free troposphere (AIRS-only) 2.5 degrees x 2 degrees V005 (AIRS3C2M) at GES DISC

The Atmospheric Infrared Sounder (AIRS) is a grating spectrometer (R = 1200) aboard the second Earth Observing System (EOS) polar-orbiting platform, EOS Aqua. In combination with the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil (HSB), AIRS constitutes an innovative atmospheric sounding group of visible, infrared, and microwave sensors. This product is the AIRS mid-tropospheric Carbon Dioxide (CO2) Level 3 Monthly Gridded Retrieval, from the AIRS instrument on board of Aqua satellite. It is a monthly gridded data, at 2.5x2 deg (lon)x(lat) grid cell size. The data is in mole fraction units (data x 10^6 =ppm in volume). This quantity is not a total column quantity because the sensitivity function of the AIRS mid-tropospheric CO2 retrieval system peaks over the altitude range 6-10 km. The quantity is what results when the true atmospheric CO2 profile is weighted, level-by-level, by the AIRS sensitivity function. The file format is HDF-EOS 2.12 corresponding to HDF4. This AIRS mid-tropospheric CO2 Level 3 Monthly Gridded Retrieval Product contains standard retrieval means, standard deviations and input counts as well as the latitude and longitude arrays giving the centers of the grid boxes. Each file covers a calendar month. The mean values are simply the arithmetic means of the individual CO2 retrievals which fall within that grid box over the month. The mid-tropospheric CO2 retrievals have been averaged and binned into 2.5 degree longitude x 2 degree latitude grid cells, from -180.0 to +180.0 deg longitude and from -60.0 to +90.0 deg latitude. For each grid map of 4-byte floating-point mean values there is a corresponding 4-byte floating-point map of standard deviation and a 2-byte integer grid map of counts. The counts map provides the user with the number of points per bin that were included in the mean.

FPI usually operates in Fast Survey (FS) Mode in the MMS Region Of Interest (ROI) for the current Mission Phase. Data are taken at Burst (30/150 ms for DES/DIS) Resolution in this Mode. Data are also made available at Survey (4.5 s, etc.) Resolution. Per Mission Design, not all Burst Resolution Data are downlinked, but all Survey Data are downlinked. Planning around Calibration Activities, avoidance of Earth Radiation Belts, etc., when possible, FPI usually operates in Slow Survey (SS) Mode (60 s Resolution) outside of ROI, and then only the 60 s Resolution Survey Data are available. This Product contains Partial Moments that come from performing the Standard Moment Integrals over a limited Portion of Velocity Space. The resulting Quantities are named similarly to their corresponding Standard Moments, but are decorated with 'part' to differentiate. For example, density_part is the Density Moment integrated from a particular Energy Step to Infinity. These Partial Moments are formed from the indicated Data Type (DES/DIS Burst, FS or SS). For convenience, some additional Parameters are included to augment those most commonly found in a Moments Product of this sort, plus Time Stamps and other Annotation characterizing the State of the Instrument System at the indicated Time.
