IHW COMET HALLEY INFRARED FILTER CURVE MEASUREMENTS V1.0

NASA's International Halley Watch (IHW) has created a Comet Halley Archive. The collection of data spans the full wavelength range as submitted by scientists to the IHW. The observations belong to one of the following Disciplines: Amateur, Astrometry, Infrared Studies, Large-Scale Phenomena, Meteor Studies, Near-Nucleus Studies, Photometry and Polarimetry, Radio Studies, and Spectroscopy and Spectrophotometry. The data collected by these nine disciplines were augmented by Spacecraft measurements. The data were submitted to IHW, but the evaluation and selection for the Archive has been the primary responsibility of the Discipline Specialist Teams for each network in cooperation with the Lead Center. The data from the Infrared Studies Network includes measurements of the transmission for 46 filter curves.

Gold Level L2 Molecular Oxygen Density Profile

O2 is derived from measurements of stellar occultation in the Shumann Runge continuum. \n   As the star rises or sets relative to the satellite position the stellar spectrum is measured across \n   the GOLD spectral bandpass, from 132 to 162 nm. Geolocation of the OCC L1B data provides the \n   line-of-sight tangent altitude vs. time during the occultation. This results in a 2-dimensional \n   map of the stellar signal, in counts or calibrated geophysical units (irradiance), vs. wavelength \n   and tangent altitude. A sample of this image is represented in the top left panel of the OCC L1D \n   image in Figure 3-22.\n   \n      The measured counts profile is then normalized by the unattenuated, exo-atmospheric spectrum, yielding \n   the slant path transmission profile vs. wavelength at the native L1C spectral sampling of 0.12 nm. \n   The defining characteristic of the atmospheric transmission is that it is completely independent of \n   instrument calibration or absolute accuracy. The full transmission spectrum is binned into a small \n   number of 2-nm spectral channels for use in the retrievals. These retrieval channels are chosen to \n   span the spectral dependence of the O2 absorption cross-section in order to maximize the O2 retrieval \n   altitude range (approximately 120-240 km). In the Version 1 O2DEN data set two spectral channels \n   are used, centered at 142- and 159-nm.\n      \n   Since stars rise or set at approximately 3 km/sec, as observed from orbit, the 100-msec occultation \n   cadence results in a measurement of extremely high (sub-km) vertical resolution. The data are binned \n   to enhance signal-to-noise, producing an effective vertical resolution of 10 km or less, which is \n   sufficient to easily resolve the scale height of the O2 thermospheric profile.\n      \n   The algorithm uses an optimal estimation routine, which provide a complete error analysis and \n   retrieval diagnostics such as averaging kernels and information content. A data vector constructed \n   from the multiple spectral channels of slant path transmission is used to derive the atmospheric \n   state vector – O2 density vs. geometric altitude – via a nonlinear, iterative inversion. The retrieved \n   O2 density profile is reported on a fixed altitude grid with 5-km spacing. The valid altitude range \n   varies for each event, but generally ranges from ~120 – 240.

BOREAS TE-12 Leaf Optical Data for SSA Species

The BOREAS TE-12 team collected several data sets in support of its efforts to characterize and interpret information on the reflectance, transmittance, and gas exchange of boreal vegetation. This data set contains measurements of hemispherical spectral reflectance and transmittance factors of individual leaves, needles (ages: current and past 2 years' growth, i.e., for 1993, the growing seasons of 1993, 1992, and 1991 were measured; in 1994, the growing seasons of 1994, 1993, and 1992 were measured), twigs (reflectance only), and substrate at near-normal incidence measured using a LI-COR LI-1800-12 integrating sphere attached to a Spectron Engineering SE590 spectroradiometer. Procedures of Daughtry et al. (1989) were followed. These procedures permitted measurement of samples that: 1) filled the entire integrating sphere sample port, and 2) were narrow with a length greater than the sample port diameter. Optical properties were measured at the SSA Fen,YJP, YA, and OBS sites.

CAMEX-3 CLOUD AND AEROSOL PARTICLE CHARACTERIZATION (CAPAC) V1

CAPAC is a series of three instruments: the Forward Scattering Spectrometer Probe model 300 (FSSP-300), the Two Dimensional Optical Array Probes [Cloud and Precipitation Probes (2D-P)] and the CAPAC video. These instruments flew during CAMEX-3 upon the NASA DC-8 mounted on the left wing. Cloud and aerosol particles were exposed to laser light to measure particle size from 0.3 micrometer to 6.4 millimeter, and both size and shape between 40 micrometer and 6.4 millimeter particle diameter as function of particle size. The size distributions thus determined were integrated to yield particle surface area, and ice and liquid water contents in clouds and precipitation. The purpose of the CAMEX-3 mission was to study hurricanes over land and ocean in the U.S. Gulf of America, Caribbean, and Western Atlantic Ocean in coordination with multiple aircraft and research-quality radar, lightning, radiosonde and rain gauge sites.

BOREAS TE-18, 60-m, Radiometrically Rectified Landsat TM Imagery

The BOREAS TE-18 team used a radiometric rectification process to produce standardized digital number (DN) values for a series of Landsat TM images of the BOREAS SSA and NSA in order to compare images that were collected under different atmospheric conditions. The images for each study area were rectified by using a reference image that had clear atmospheric qualities. The reference image for the SSA was collected on 02-Sep-1994, while the reference image for the NSA was collected on 21-Jun-1995. The 23 rectified images cover the period of 07-Jul-1985 to 18-Sep-1994 in the SSA and 22-Jun-1984 to 09-Jun-1994 in the NSA.

Gold Level L2 ratio of the column abundance of thermospheric O relative to N2

The GOLD daytime disk scan measurements are used to derive the TDISK data product, which is the effective disk neutral temperature at a height of approximately 150 km. TDISK is derived for each valid dayside Level 1C pixel for approximately 68 disk scan measurements performed per day by GOLD in nominal operation.\n\nAlgorithm heritage\n\nThe retrieval algorithm is an extension of those previously used to derive temperature from limb measurements of LBH intensity from the HITS instrument (Aksnes et al., [2006]; Krywonos et al. [2012]).\n\nAlgorithm theoretical basis\n\nGOLD measurements have a higher signal-to-noise ratio than HITS and a spectral range that includes more of the total N2 LBH emission (132 - 162 nm). Effective neutral temperatures near ~150 km altitude are retrieved by fitting the observed rotational structure of the N2 LBH bands using an optimal estimation routine. Retrieved parameters also include the upper vibrational level (v'=0-6) relative intensities (i.e. populations), a constant background, wavelength shift, and wavelength dispersion (constant term).\n\nReferences\n\nAksnes, A., R.

CALIPSO Wide Field Camera Level 1B 125m Native Science data, Validated Stage 1 V3-02

CAL_WFC_L1_125m-ValStage1-V3-02 data are Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Wide Field Camera (WFC) Level 1B 125 m Native Science data, Validated Stage 1 Version 3-02. Data collection for this product is ongoing. Version 3.02 represents a transition of the Lidar, Imaging Infrared Radiometer (IIR), and WFC processing and browse code to a new cluster computing system. No algorithm changes were introduced, and very minor changes were observed between V3.01 and V3.02 as a result of the compiler and computer architecture differences. The primary WFC Level 1B data products are calibrated radiance and bidirectional reflectance registered to an Earth-based grid centered on the Lidar ground track. During normal operation, the WFC acquires science data only during the daylight portions of the CALIPSO orbits. The 1 km Native Science grid covers the full 61 km swath centered on the Lidar track. The 125 m Native Science grid contains only the central 5 km wide high-resolution portion of the WFC swath. Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) was launched on April 28, 2006, to study the impact of clouds and aerosols on the Earth's radiation budget and climate. It flies in the international A-Train constellation for coincident Earth observations. The CALIPSO satellite is comprised of three instruments, the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP), IIR, and WFC. CALIPSO is a joint satellite mission between NASA and the French Agency, CNES (Centre National d'Etudes Spatiales).

BOREAS TE-19 Ecosystem Carbon Balance Model

The BOREAS TE-19 team developed a model called the Spruce and Moss Model (SPAM) designed to simulate the daily carbon balance of a black spruce/moss boreal forest ecosystem. It is driven by daily weather conditions, and consists of four components: (1) soil climate; (2) tree photosynthesis and respiration; (3) moss photosynthesis and respiration; and (4) litter decomposition and associated heterotrophic respiration. The model simulates tree gross and net photosynthesis, wood respiration, live root respiration, moss gross and net photosynthesis, and heterotrophic respiration (decomposition of root litter, young needle and moss litter, and humus). These values can be combined to generate predictions of total site net ecosystem exchange of carbon (NEE), total soil dark respiration (live roots + heterotrophs + live moss), spruce and moss net productivity, and net carbon accumulation in the soil. The files include source code and sample input and output files in ASCII format.

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

Heliocentric trajectories for Giotto 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| 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\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.

BOREAS TE-18 Biomass Density Image of the SSA

This biomass density image covers almost the entire BOREAS SSA. The pixels for which biomass density is computed include areas that are in conifer land cover classes only. The biomass density values represent the amount of overstory biomass (i.e. tree biomass only) per unit area. It is derived from a Landsat-5 TM image collected on 02-Sep-1994. The technique that was used to create this image is very similar to the technique that was used to create the physical classification of the SSA. The data are provided in a binary image file format. Companion files include (1) an image inventory listing to inform users of the images that are available and (2) example thumbnail images.
