The NOAA Geostationary Operational Environmental Satellite (GOES) key parameters are obtained from the Energetic Particle Sensor (EPS) and the magnetometer (MAG). The key parameters are a subset of the data available from the GOES Space Environment Monitor (SEM) instruments. The energetic particle fluxes are given as five-minute averaged values and the vector magnetic field is given as one-minute average values. Flux values for three integral electron channels (E >0.6 MeV, E >2.0 MeV, and E >4.0 MeV) and one differential proton channel(0.7 MeV < E <4 MeV) are provided. These data are used by NOAA Space Environment Center (SEC) for the real-time monitoring and prediction of the conditions in the Earth's space environment. A new series of GOES spacecraft began with GOES-8 launched on 4/13/94, GOES-9 launched on 5/23/95, and GOES-10 launched on 4/25/97. Typically two satellites are maintained operational,one at about 135 degrees geographic west longitude and one at about 75 degrees geographic west longitude. The satellite inclination is typically within a few tenths of a degree of the geographic equator. However, the satellites can be moved, especially during the six months to one year following launch, and the inclination can increase after years of satellite operation. Instrument data quality flags are set from real-time telemetry, or, in the case of historically-processed data sets when telemetry is not available, fixed to a level-1 instrument status flag for all data Reference: Geostationary Operational Environmental Satellite GOES I-M System Description, compiled by John Savides, Space Systems/Loral, Palo Alto, California, December 1992.

These channels were used for the correction and processing of the proton and electron data. Beginning April 8, 2003, the GOES energetic particle data are obtained from GOES 10 only.

The NOAA Geostationary Operational Environmental Satellite (GOES) key parameters are obtained from the Energetic Particle Sensor (EPS) and and the magnetometer (MAG). The key parameters are a subset of the data available from the GOES Space Environment Monitor (SEM) instruments. The vector magnetic field is given as one-minute averaged values in three coordinate systems: (1) Spacecraft (s/c) P,E,N, (2) GSM x,y,z, (3) GSE x,y,z s/c mag. field is defined as: Hp, perpendicular to the satellite orbital plane or parallel to the Earths spin axis in the case of a zero degree inclination orbit; He, perpendicular to Hp and directed earthwards; and Hn, perpendicular to both Hp and directed eastwards. These data are used by NOAA Space Environment Center (SEC) for the real-time monitoring and prediction of the conditions in the Earth's space environment.

Satellite positions and velocities derived from SSCWEB GEI ephemeris, interpolated to one minute time resolution; perpendicular vectors for ENP coordinate system derived from pos X vel. B field vectors in LH-ENP and GEI systems, B field total magnitude, magnetotorquer counts, and data quality flags derived from 512 msec binary GOES data files. General Comments from Dr. Howard J. Singer (GOES Magnetometer PI) 1. Data Description: A full description of the GOES magnetometer data, including use of the quality flags and torquer current information, is contained in a GOES 8-12 Magnetometer Readme File prepared by Dr. Howard J. Singer. The GOES data have been prepared at NOAA Space Weather Prediction Center (SWPC) by Dr. Howard J. Singer with major data processing and data evaluation contributions by SWPC staff, Lorne Matheson and Ann Newman, as well as coordinate transformation development by Dr. Paul Loto aniu (University of Colorado/SWPC). 2. Coordinate description for PEN: .Hp: magnetic field vector component, points northward, perpendicular to orbit plane which for a zero degree inclination orbit is parallel to Earth's spin axis. .He: magnetic field vector component, perpendicular to Hp and Hn and points earthward. .Hn: magnetic field vector component, perpendicular to Hp and He and points eastward. Ht: total field. 3. Magnetometer offsets and noise: GOES 8-12 spacecraft are 3-axis stabilized. There is only one opportunity for a spin maneuver at the beginning of the mission to determine on-orbit magnetic field offsets. There are additional complications that result from needing to know the changing offsets introduced by torquer coils on the satellites. While comparisons of GOES data to model fields during quiet times and comparisons to nearby encounters with other spacecraft are used to demonstrate the observed data values are reasonable, caution should be used in assigning absolute accuracy. While there has been a significant effort to remove the effects of torquer coil interference in the 0.512 s data, there can be small, typically less than 1 nT spikes in the data at the time of torquer current changes. More information on this topic is included the more extensive readme file. This file is a living document that will be updated periodically. 4. Orbital Inclination: During the primary operational lifetime of the GOES satellites, the satellite inclination is typically kept within a few tenths of a degree of 0 degrees inclination; however, as the satellite ages, the inclination can grow to several degrees.

Editor-A data are only acquired with the real-time operation in Usuda Deep Space Center (UDSC),Japan, while the Editor-B data are 24-hours continuouslyrecorded in the onboard tape recorders and are dumpedover the NASA/JPL Deep Space Network (DSN) stations Please use the Editor-A LEP dataset prior to the Editor-B LEP dataset sinceplasma moments in the Editor-A data are more reliable. (Plasma moments inthe Editor-B are calculated onboard.) The ion energy analyzer (LEP-EAi) has two energy scan mode: RAM-A (60eV to 40 keV) and RAM-B (5 keV to 40 keV). The energy scan mode is automatically selected onboard depending on the incoming ion fluxes. At present, only the plasma moments in the RAM-A mode are plotted (listed) for the LEP-EAi data. (The LEP-EAi moments are presented by the solid lines in the plot.) The plasma moment data of the solar wind analyzer (LEP-SW) should be used only qualitatively.

Version 6 data processing replaced version 5 processing for data after March 10, 2006, when the CPI team started using 64 energy steps per spectrum instead of the previously used 32 steps per spectrum. The change was made to ensure that even for very cold flows, the spectrum would have a sufficient number of significant points to derive moments. The change resulted in 96s spectra and 96s-resolution moments, vs. 48s previously.

Assuming no helium (0.3 - several hundred) if the density is less than 0.3/cc the higher moments (VEL,TEMP) shall not be used because of the poor counting statistics.

Geotail Prelaunch Report, April 1992 The sensor providing data here (called EFD-P in report above) measures the difference of electric potential between two electrodes (probes) immersed in the plasma. There are two sperical probes and two wire antennas each of which is extended by 50 meters from the satellite in its rotational plane. The two sperical probes are opposite each other (100 meters tip-to-tip) as are the two wire antennas. The probe pairs are orthogonal to each other. Diving the potential difference by the distance between the probes or the centers of the conducting portion of the wire antennas gives the electric field component along the probe extension. The measurement of the electric field in the satellite rotational plane gives the vector electric field when the electric field along the magnetic field is much smaller than the perpendicular component.

The NOAA Geostationary Operational Environmental Satellite (GOES) key parameters are obtained from the Energetic Particle Sensor (EPS) and the magnetometer (MAG). The key parameters are a subset of the data available from the GOES Space Environment Monitor (SEM) instruments. The energetic particle fluxes are given as five-minute averaged values and the vector magnetic field is given as one-minute average values. Flux values for three integral electron channels (E >0.6 MeV, E >2.0 MeV, and E >4.0 MeV) and one differential proton channel(0.7 MeV < E <4 MeV) are provided. These data are used by NOAA Space Environment Center (SEC) for the real-time monitoring and prediction of the conditions in the Earth's space environment. A new series of GOES spacecraft began with GOES-8 launched on 4/13/94, GOES-9 launched on 5/23/95, GOES-10 launched on 4/25/97, GOES-11 launched on 5/3/2000, and GOES-12 launched on 7/23/2001. Typically two satellites are maintained operational,one at about 135 degrees geographic west longitude and one at about 75 degrees geographic west longitude. The satellite inclination is typically within a few tenths of a degree of the geographic equator. However, the satellites can be moved, especially during the six months to one year following launch, and the inclination can increase after years of satellite operation. Instrument data quality flags are set from real-time telemetry, or, in the case of historically-processed data sets when telemetry is not available, fixed to a level-1 instrument status flag for all data Reference: Geostationary Operational Environmental Satellite GOES I-M System Description, compiled by John Savides, Space Systems/Loral, Palo Alto, California, December 1992.

The ROTI index is the standard deviation of the Rate of change of TEC (ROT) during a 5-minute interval. TEC is the Total Electron Content measured between a GPS satellite and ground receiver station.
The IGS global system of satellite tracking stations, Data Centers, and Analysis Centers puts high-quality GPS data and data products on line in near real time to meet the objectives of a wide range of scientific and engineering applications and studies. The IGS collects, archives, and distributes GPS observation data sets of sufficient accuracy to satisfy the objectives of a wide range of applications and experimentation. These data sets are used by the IGS to generate the data products mentioned above which are made available to interested users through the Internet. In particular, the accuracies of IGS products are sufficient for the improvement and extension of the International Terrestrial Reference Frame (ITRF), the monitoring of solid Earth deformations, the monitoring of Earth rotation and variations in the liquid Earth (sea level, ice-sheets, etc.), for scientific satellite orbit determinations, ionosphere monitoring, and recovery of precipitable water vapor measurements. The primary mission of the International GPS Service, as stated in the organization's 2002-2007 Strategic Plan, is The International GPS Service is committed to providing the highest quality data and products as the standard for global navigation satellite systems (GNSS) in support of Earth science research, multidisciplinary applications, and education. These activities aim to advance scientific understanding of the Earth system components and their interactions, as well as to facilitate other applications benefiting society. The IGS Terms of Reference (comparable to the by-laws of the organization) describes in broad terms the goals and organization of the IGS. To accomplish its mission, the IGS has a number of components: an international network of over 350 continuously operating dual-frequency GPS stations, more than a dozen regional and operational data centers, three global data centers, seven analysis centers and a number of associate or regional analysis centers. The Central Bureau for the service is located at the Jet Propulsion Laboratory, which maintains the Central Bureau Information System (CBIS) and ensures access to IGS products and information. An international Governing Board oversees all aspects of the IGS. The IGS is an approved service of the International Association of Geodesy since 1994 and is recognized as a member of the Federation of Astronomical and Geophysical Data Analysis Services (FAGS) since 1996. The IGS collects, archives, and distributes GPS observation data sets of sufficient accuracy to meet the objectives of a wide range of scientific and engineering applications and studies. These data sets are used to generate the following products: * GPS satellite ephemerides * GLONASS satellite ephemerides * Earth rotation parameters * IGS tracking station coordinates and velocities * GPS satellite and IGS tracking station clock information * Zenith tropospheric path delay estimates * Global ionospheric maps IGS products support scientific activities such as improving and extending the International Earth Rotation Service (IERS) Terrestrial Reference Frame (ITRF), monitoring deformations of the solid Earth and variations in the liquid Earth (sea level, ice sheets, etc.), and in Earth rotation, determining orbits of scientific satellites and monitoring the ionosphere. For example, geodynamics investigators who use GPS in local regions can include data from one or more nearby IGS stations, fix the site coordinates from such stations to their ITRF values, and more importantly, use the precise IGS orbits without further refinement. Data from an investigator's local network can then be analyzed with maximum accuracy and minimum computational burden. Furthermore, the results will be in a well-defined global reference frame. An additional aspect of IGS products is for the densification of the ITRF at a more regional level. This is accomplished through the rigorous combination of regional or local network solutions utilizing the Solution Independent Exchange Format (SINEX) and a process defined in the densification section. In the future, the IGS infrastructure could become a valuable asset for support of new ground-based applications -- and could also contribute to space-based missions in which highly accurate flight and ground differential techniques are required.
