G0_K0_EP8 (spase://NOAA/NumericalData/GOES/10/SEM/PT300S)
Description
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

G0_K0_MAG (spase://NOAA/NumericalData/GOES/10/MAG/PT1M)
Description
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.  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.

 longitude. The satellite inclination
 is typically within a few tenths of a
 degree of the geographic equator.

G6_K0_EPS (spase://NOAA/NumericalData/GOES/6/EPM/PT5M)
Description
The NOAA GOES satellites include 2 sensors: an Energetic Particle Sensor (EPS),
and a Magnetometer (MAG).
The satellites are geostationary. For older satellites, inclination may be up to
15 deg.
Data usually contains errors,especially GOES-6 EPS E1, which suffers from
radiation damage.
The EPS data are 5-min. averages, the MAG data are 1-min. averages. 
The NOAA Space Environment Lab (SEL), Space Environ. Services Center (SESC) uses
this data in real time for forecasting and monitoring.

G8_K0_EP8 (spase://NOAA/NumericalData/GOES/8/EPS/PT5M)
Description
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

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. The LEP-SW plasma moments are plotted 
(listed) when the energy scan mode of LEP-EAi is RAM-B. (The 
LEP-SW moments are presented by the dotted lines in the plot.)

Description
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.

Modification History
First Delivery version, 7-OCT-1993
v2.0,  12-APR-94, RLD Changed dimensions to 3 and 2 at recommendation of
                      Mona Kessel. Jeff Love (CDFSUPPORT) helped clean up
                      dimension problems.
v2.1,  20-JUL-94, RLD Change VALIDMIN dates for CPI data to be 1 Oct 92.
                      Added items to TEXT field to include all KPs and
                      defined coordinate system used for velocities.
v2.2,  24-JAN-95, RLD Added some new comments to the description section.
v2.3,  19-MAY-95, RLD Added SW_V Z-component.
v2.31,  8-Jun-95, RLD Corrected dependent variables to differentiate
                      between CDF's 2-D size 2 & 3 (i.e., 2 &
                      3-dimensional velocities).
v2.4,  28-Sep-95, RLD Updated text & variable min/max values for consistency.
v2.41, 21-DEC-95, RLD Updated for KPGS v2.3 delivery. Official external
                      version of ST is now v04.

GE_K0_EFD (spase://JAXA/NumericalData/Geotail/EFD/PT64S)
Description
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.

GOES11_K0_EP8 (spase://NOAA/NumericalData/GOES/11/EPS/PT5M)
Description
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

GOES11_K0_MAG (spase://NOAA/NumericalData/GOES/11/MAG/PT1M)
Description
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.  A new
 series of GOES spacecraft began
 with GOES-8 launched on 4/13/94,

 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.  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
 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

GPS_TEC15MIN_IGS (spase://NASA/NumericalData/IGS/GPS_Receiver/TEC/PT15M)
Description
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.
