Comet Wild 2 Ephemeris, Heliocentric Trajectories, Heliographic, Heliographic Inertial, and Solar Ecliptic Coordinates, HelioWeb, Daily Data

Heliocentric trajectories for Comet Wild 2 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.

BOREAS RSS-17 Dielectric Constant Profile Measurements

The BOREAS RSS-17 team acquired and analyzed imaging radar data from the ESA's ERS-1 over a complete annual cycle at the BOREAS sites in Canada in 1994 to detect shifts in radar backscatter related to varying environmental conditions. This data set consists of dielectric constant profile measurements from selected trees at various BOREAS flux tower sites. The relative dielectric constant was measured at C-band (frequency = 5 GHz) as a function of depth into the trunk of three trees at each site. Measurements were made during April 1994 with an Applied Microwave Corporation field PDP fitted with a 0.358-cm (0.141-inch) diameter coaxial probe tip.

CALIPSO Lidar Level 1.5 Profile, V1-01

CAL_LID_L15-Standard-V1-01 is the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) Lidar Level 1.5 Profile, Version 1-01 data product. Data for this product was collected using the CALIPSO Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument. The version of this product was changed from 1-00 to 1-01 to account for a change in the operating system of the CALIPSO production cluster. This product is a continuous segment of calibrated, geolocated, cloud-cleared, and spatially averaged profiles of lidar attenuated backscatter. Data collection for this product is ongoing. These profiles are derived via synthesizing the CALIPSO lidar Level 1B profile and lidar Level 2 5 km aerosol profile products with the lidar Level 2 Vertical Feature Mask (VFM) product. The lidar Level 1.5 standard data product is derived using standard Version 4.11 Level 1B and Version 4.21 Level 2 data products as input. 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 comprises three instruments: CALIOP, Imaging Infrared Radiometer (IIR), and Wide Field Camera (WFC). CALIPSO is a joint satellite mission between NASA and the French Agency CNES (Centre National d'Etudes Spatiales).

BOREAS RSS-14 GOES-7 Level-1a Visible, Infrared, and Water Vapor Images

The level-1a BOREAS GOES-7 image data was collected by Remote Sensing Science Team 14 (RSS-14) personnel at the Florida State University and processed to level-1a products by BORIS personnel. The primary objective for the GOES-7 images in 1994 was to collect visible, infrared (IR), and water vapor channel data covering the BOREAS region at a sufficiently high temporal frequency for subsequent use in analyzing weather events and deriving temporal surface radiation parameters and patterns that existed during the Focused and Intensive Field Campaigns (FFCs and IFCs). The transition and shifting of satellites from GOES-7 to GOES-8 in 1995 enabled good quality images to be acquired over the BOREAS region four times per day from January to June, giving a reasonable monitoring dataset. The data cover the period of 01-January-1994 through 08-July-1995 with partial to complete coverage on the majority of the days. The data include three-bands with eight-bit pixel values. No major problems with the data have been identified.

Helios 1 E3 Magnetometer (Ness et al.) 1-hr Data

Task of the HELIOS mission was the exploration of the inner heliosphere, inside the Earth's orbit to 0.3 AU. The Rome-GSFC magnetic field experiment has been a joint venture of an italian group (University of Rome and CNR/Istituto Fisica Spazio Interplanetario, Frascati) and an american group of NASA/Goddard Space Fligth Center, under the responsibility of F. Mariani and N.F.Ness, respectively. A description of the experiment can be found in the NASA-GSFC report X-692-75-112 (1975), by C. Scearce et al. The instrument is a dual configuration of two tri-axial fluxgate magnetometers operating at four different sensitivities (from 0.84 to 0.03 nT). The time resolution, depending the operation mode, telemetry format, and bit rate, for most cases varied from 0.07 to 1.5 seconds. This data set contains hour-averaged magnetic field vectors from the the Ness/Mariani experiment on Helios 1 [or 2]. Each record contains time, magnetic field intensity and cartesian components in spacecraft-centered solar ecliptic coordinates, standard deviations, numbers of fine-scale points in the average, and an instrument mode indicator. It should be noted that the "average" mode, which was used a minority of the time and involved on-board averaging, may have incorrectly handled range changes caused by occasional significant changes in ambient field intensity. The data set had not been filtered for this effect upon delivery to NSSDC. The data files are named either HE1MGA.asc, for one file covering the entire 1974 - 1981 period, or HE1MGAyy.asc, for one year intervals of data.

BOREAS RSS-14 GOES-8 Level-1a Visible, Infrared and Water Vapor Images

The BOREAS RSS-14 team collected and processed several GOES-7 and GOES-8 image data sets that covered the BOREAS study region. The level-1a GOES-8 images were created by BORIS personnel from the level-1 images delivered by FSU personnel. The data cover 14-Jul-1995 to 21-Sep-1995 and 12-Feb-1996 to 03-Oct-1996. The data start out as three bands with 8-bit pixel values and end up as five bands with 10-bit pixel values. No major problems with the data have been identified. The differences between the level-1 and level-1a GOES-8 data are the formatting and packaging of the data. The images missing from the temporal series of level-1 GOES-8 images were zero-filled by BORIS staff to create files consistent in size and format. In addition, BORIS staff packaged all the images of a given type from a given day into a single file, removed the header information from the individual level-1 files, and placed it into a single descriptive ASCII header file. The data are contained in binary image format files. Companion files include (1) an image inventory listing to inform users of the images that are available and (2) example thumbnail images.

CALIPSO Lidar Level 0 PIVB data

CAL_LID_L0_PIVB-Standard-V1-00 is the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Lidar Level 0 PayloadInstrument Verification and Block (PIVB), Version 1-00 data product. These data were collected intermittently between August 2016 and June 2023 using the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP). The CALIPSO payload flight software, when commanded, creates Lidar Level 0 PIVB data packets for each of the three channels: 532 nm parallel, 532 nm perpendicular, and 1064 nm. These packets contain the altitude-dependent profiles (15 m resolution) of the raw backscatter signals acquired in the high and low gain channels over 15 consecutive laser pulses prior to being processed by CALIOP’s on-board profile averaging algorithm. Also included in the product are time and position information for each laser pulse, associated instrument engineering data, and an array containing the on-board measurement altitudes. No post-processing is done for the PIVB data, so the backscatter profiles have not been altitude-registered, geolocated, range-corrected, or calibrated. The PIVB data is not part of routine science data capture and is acquired only episodically throughout the latter portion of the CALIPSO mission. CALIPSO was a partnership between NASA and the French Space Agency, CNES. CALIPSO was launched on April 28, 2006 to study the many roles played by clouds and aerosols in Earth’s climate and weather. It flew in the international A-Train constellation for coincident Earth observations from launch until September 13, 2018, when CALIPSO began lowering its orbit from 705 km to 688 km (428 miles) above the Earth to resume formation flying with CloudSat as part of the “C-Train”.

BOREAS RSS-17 1994 ERS-1 Level-3 Freeze/Thaw Backscatter Change Images

The BOREAS RSS-17 team acquired and analyzed imaging radar data from the ESA's ERS-1 over a complete annual cycle at the BOREAS sites in Canada in 1994 to detect shifts in radar backscatter related to varying environmental conditions. Two independent transitions corresponding to soil thaw and possible canopy thaw were revealed by the data. The results demonstrated that radar provides an ability to observe thaw transitions at the beginning of the growing season, which in turn helps constrain the length of the growing season. The data set presented here includes change maps derived from radar backscatter images that were mosaicked together to cover the southern BOREAS sites. The image values used for calculating the changes are given relative to the reference mosaic image. Due to copyright issues, the 01-March-1994 reference image is not included on the CD-ROM and is not publically available. See the accompanying guide document for information about how to possibly acquire the data. The data are stored in binary image format files.
