Alouette-2 Topside Sounder Average Ionogram over Fairbanks, AK: ULA, Latitude 65, Longitude 212

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.

STPSat-1 SHIMMER OH Data

This dataset contains daily averaged mesospheric hydroxyl, OH, radiance profiles of solar resonance fluorescence measured near 309 nm by the Spatial Heterodyne Imager for MEsospheric Radicals, SHIMMER, onboard STPSat-1. OH data were obtained by imaging the limb every 20 s between 58°N and 58°S. These radiance profiles were inverted to retrieve daily averaged mesospheric OH densities between 60 and 90 km in 2 km increments. A total of 1816 OH profiles are available, 881 from the ascending, A, portion of the orbit and 935 from the descending, D, portion of the orbit. Because the satellite is moving eastward at latitudes between 50°N and 58°N, the profiles from the A portion are about 3 hours earlier in local solar time than the D portion in this latitude band. The OH number density profile data are stored in directories for the tropics, 0_to_15N, and for the mid-latitudes, 50N_to_58N. See SHIMMER Data Manual for a list of missing days. They are available in ASCII format in five columns:\n\n* Altitude\n* OH densities\n* Uncertainty in the OH densities, 1 σ\n* OH radiances (uninverted intensities along the line of sight)\n* Uncertainty in the OH radiances.\n\nIn addition, there are "showstat" summary plots stoe\red in postscript files with relevant viewing conditions for each of the six data periods (either tropics or mid-latitudes for each of the three years). Each of the figures has 6 panels that include:\n\n* Number of spectra obtained on each day\n* Solar Zenith Angle, SZA\n* Solar Scattering Angle, SSA\n* Latitude of the limb tangent point\n* Local Solar Time, LST, at the tangent point\n* Altitude range of the limb observation\n\nThe altitude range of the limb observation nominally spans from 35 kam to 100 km, though on occasion it can be as high as from 65 kam to 130 km.

THEMIS-B: On Board spin fits (FIT) of Electric (EFI) and Magnetic (FGM) field. On-Board Spin-fit electric and magnetic field data

THEMIS-B: On Board spin fits of Electric (EFI) and Magnetic (FGM) fields. This file contains data EFI and FGM that has been despun on-board to 3 second resolution. It stores meta information like the number of points that contributed to each spin and the standard deviation of those points. For the EFI data it also stores variables with the Z component of the EFI data zeroed and the Z component of the EFI estimated using the E.B=0 equality. The need to use an estimated Z axis for the EFI is due to error in measurements from the EFI axial booms. These data are provided in DSL (despun spacecraft L-Z vector), GSM, and GSE coordinates.

STPSat-1 SHIMMER PMC Data

This dataset contains Polar Mesospheric Clouds (PMCs) observed by the Spatial Heterodyne Imager for MEsospheric Radicals (SHIMMER) onboard the STPSat-1 satellite. The PMC (primarily a summertime phenomenon) data are derived from over a million limb images during its three-year mission, minus September through November for each year. Each file has a five-line header that includes: (1) Year and day of the year (DOY), (2) Total number of PMC detected on that day, (3) The number of PMC detected when using a phase function of the ice particles, (4) Hydroxyl (OH) radiances at 80 and 87 km, and (5) Labels of the output: Year, DOY, GMT, LAT, LON, LST, SSA, SZA, PMCRAW (1 for PMC detection and 0 for none), PMCMIE (detection above the applied threshold), BGRND (average Rayleigh scattered background signal in kR/nm), BRT (background corrected peak brightness in kR/nm), THRRAW (threshold used to identify a PMC), THRPHS (threshold used to detect PMC in kR/nm), PK (altitude of the peak emission in km), OH80 (OH solar resonance fluorescence radiance detected at 80 km in kR), OHE80 (uncertainty for the 80 km OH radiance in kR), OH87 (OH solar resonance fluorescence radiance detected at 87 km in kR), and OHE87 (uncertainty for the 87 km OH radiance in kR).  \n  \nIn addition to the PMC data, there are PMC maps and summary figures for each year of operations.  The first figure for each year is map_YYYY.ps, where YYY represents the year. This shows the geographic location of each detected PMC, without regard to when it was detected. Also indicated on the maps are the total number of images tested for a PMC as well as the total number of PMC detected for each year. The second figure (summary_YYYY.ps) shows a time series of some important results of the analysis: the number of SHIMMER images tested,  a time series of PMC detections for the year, a time series of thresholded PMC detections, and  a time series of PMC altitudes defined as the altitude of peak brightness.

CLAMS MODIS L2 Aerosols

CLAMS_MODIS_L2_AEROSOL_PRODUCTS data were collected during the Chesapeake Lighthouse and Aircraft Measurements for Satellites (CLAMS) experiment.The Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol data products give the ambient aerosol optical thickness over the oceans and over a portion of the continents. The aerosol size distribution is derived over the oceans, and the aerosol type is derived over the continents. Daily Level 2 data were produced at the spatial resolution of a 10??10 1-km (at nadir)-pixel array. The MODIS_CLAMS_L2_AEROSOL_PRODUCTS cover the time period from July 10, 2001 (Julian day 191) to August 2, 2001 (Julian day 214) over the spatial region nomally from -106 degree longitude to -42 degree longitude and from 57 degree N latitude to 18 degree N latitude.The MODIS instrument provides high radiometric sensitivity (12 bit) in 36 spectral bands ranging in wavelength from 0.4 ??m to 14.4 ??m. Two bands are imaged at a nominal resolution of 250 m at nadir, with five bands at 500 m and the remaining 29 bands at 1,000 m. A ??55-degree scanning pattern at the EOS orbit of 705 km achieves a 2,330-km swath and provides global coverage approximately every two days.

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

Heliocentric trajectories for Suisei 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.
