Bowen Ratio Surface Flux: Smith (FIFE)

The Bowen Ratio Surface Flux Observations (Smith) Data Set contains surface flux measurements made at selected sites within the FIFE area. The collection effort was conducted in 1987, 1988, and 1989 from sites equipped with Bowen ratio equipment operated by several different groups. Each surface flux station was capable of measuring the fluxes of net radiation, sensible heat, and latent heat using. The Bowen ratio stations measured the soil heat flux as well. The surface flux and micrometeorological measurements available in this data set were collected from 2 locations within the FIFE study area. One of these sites was located at the bottom of a valley while the other was on the top of a ridge. During the IFC's data were collected daily.

DE 1 8-sec Position Data

Two Dynamics Explorer (DE) spacecraft were launched August 3, 1981, and placed into coplanar polar orbits with DE-1 in a highly elliptical orbit and DE-2 in a lower more circular orbit. The primary objective of the DE program was to investigate magnetosphere-ionosphere-atmosphere coupling processes. The DE mission provided a wealth of new information on a wide variety of magnetospheric plasma wave phenomena including auroral kilometric radiation, auroral hiss, Z mode radiation, narrow-band electromagnetic emissions associated with equatorial upper hybrid waves, whistler mode emissions, wave-particle interactions stimulated by ground VLF transmitters, equatorial ion cyclotron emissions, ion Bernstein mode emissions, and electric field turbulence along the auroral field lines. These files contain 8 second resolution emphemeris and spacecraft attitude parameters that coincide with DE-1 telemetry frames containing PWI lowrate data. These parameters are not to be taken as an authoritative set, but are convenient when working with PWI science data products. Most of these data are provided in the Geocentric Equatorial Inertial (GEI) TOD reference frame. The Z axis of the GEI frame is parallel to Earth's spin axis; the X axis points towards the First Point of Aries with the Y axis aligned so as to generate a right-handed coordinate system.

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

Heliocentric trajectories for Planet Jupiter 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.

CRRES magnetic field orbital data

The magnetic field files (CRnnnn.FPM) contains magnetic field components converted from the CRRES tri-axial fluxgate magnetometer sensor output.  This data set, however, is different from the ones on the Aerospace agency tapes.  The experimenter magnetic field files (which had neither the full time resolution nor the magnetic field intensity resolution of the original magnetometer outputs) were converted to field components in magnetometer sensor coordinates using the software and final calibration coefficient files provided by the magnetometer PI (Dr. Howard Singer, SEL).  The original magnetic field files for orbits 6-350 were not readilly available, but the converted files were, so for the sake of uniformity, it was decided to provide the converted files\ninstead of the originals.  For those who might wish to get back to the original data, the source code (MAGMPC5.FOR) and calibration files (MAGnn.CAL)\nwhich were used to generate the .FPM files are provided.  The original CR0237.MAG file is available on CD-8 for comparison with any results of an\ninversion program written by the user.  A program which dumps the CRnnnn.FPM files is also provided on CD-35 (FPMTEST.EXE).  This program prints out the\nUT, three magnetic field components in magnetometer coordinates, total B, and the pitch-angle calculated for the MEA (or a user-selected set of direction\ncosines).  The source code, FPMTEST.FOR, is also provided.

Bowen Ratio Surf. Flux: Fritschen (FIFE)

Surface flux measurements were made at selected sites within the FIFE area. Each surface flux station was capable of measuring the fluxes of net radiation, sensible heat, and latent heat. The Bowen ratio stations measured the soil heat flux as well. The surface flux and micrometeorological measurements available in this data set were collected from 15 locations within the FIFE study area between 1987 and 1989. Six automatic surface energy and radiation balance systems were operated continuously for 144 days from May 16 to October 16, 1987. Variables including net radiation, air temperature, vapor pressure and wind speed, were quite similar for the sites even though the sites were as much as 10 km apart and represented the four cardinal slopes and a top. The Bowen ratio was low during most of the season, increasing sharply toward the end of the season after a long dry spell. The average Bowen ratio was 0.35. About 72% of the available energy was converted into latent heat flux density. Since the data systems and instrumentation used were of similar design, the variability in results can be ascribed to treatment and locations. These results can be used to estimate the number of stations needed to represent a rolling prairie topography.
